Have ZF transmission - a few general questions

Hi there, I've read through this entire thread and found it quite enlightening (though depressing).

I have a 2000 323i Touring that just got the no-reverse issues. As it was built in June of 2000, I suspect that I have the ZF transmission (have not yet stuck my head under the car to verify but all signs point this way).

My symptoms:

For the past month or two, if I threw it into reverse too soon after starting the car, it would really pop when it went into gear.

About 4 months ago, the transmission went into limp home mode (but then never did it again)

Yesterday morning, the reverse failed completely (for the first time ever). I have tried it cold. I have raced up and down the freeway like a madman and tried it warm. Nothing helps.

So, here are my questions:

1) From reading this thread, I gather that the suspect valve that everyone is referring to in this thread is only relavant to the gm tranny. Correct?

2) In all likelihood I am looking at the cracked drum that lucifer1306217 is referring to in his/her post (thanks for that btw). If so, any recommendations on where to go to see if I can get that fixed in the San Francisco Bay Area?

3) Would a used transmission (not rebuilt) make any sense? I mean, if it is (off the top of my head) half as expensive as a rebuild, I could have two of them fail on me before I am behind the 8-ball financially. But there may be other considerations.

4) Any thoughts on what a 2000 323i Touring (gold) with 116K mi and in decent but not perfect shape would sell for (given that the transmission is busted)?

My Ride: '00 323i & 02 330xi
I too now have a no reverse issue. I have a early model 2000 323i manufactured in July/1999. I'm going to find out later today if I have a GM or ZF gear box. The car has a regular automatic transmission NOT steptronic. The car wouldn't go into reverse, I let the car run/idle for 30 mins to no avail, then drove the car around the block and that didn't help. After I drove the car a few miles to the autoshop, the damn reverse started working again.

The mechanic is a good friend of mine, who didn't understand what I was trying to tell him. I said that from what I read depending on which transmission I have it could be a few different things. A bad valve body, a bad reverse solenoid (he said there is no reverse solenoid reverse is a manual independent gear, I should of just said a bad solenoid that causes a pressure loss ), a bad snap ring/shredded reverse drum. I was trying to tell him this a specific issue with a couple of poorly built transmissions.

So, mechanic confirmed that it is a ZF transmission (no surprise there) and he has seen a bunch of these (in fact, was just finishing another one up today).

Quoted me $3200 for a new one (I think that is installed, but can't be 100% sure till I talk to him again). He's looking for a used one now.

Nuts. My old e28 hit 205K needing nothing more than a busted fuel line and new bushings (beyond the usual brakes, tires, clutch, exhaust, etc.) Never should have sold that car.

Just rode in a friend's Nissan Leaf today. Pretty awesome.

Got me thinking (as a joke): It would be cool if someone developed a simple/small electric motor kit that would back the car up for those of us with bum transmissions. It would be a hybrid, but only in reverse!

Would a GM 328i A5S325Z box fit a 323i? Or more generally, are the 'boxes interchangeable?

Not easily. If you search neil's posts in this thread you'll find that he looked into it and found a link that shows that it is way more complicated than it is worth.

At that point it would make more sense to convert to a std transmission.

My Ride: Maybe 330Xi
Trans issues 330Xi etc

I'm looking to buy a 330Xi and it has a trans issue, not like the others on here. The owner says that after it sits for awhile at work for the day or over night. It wont go into gear forward or reverse but if he lets it warm up for about five mins it goes into gear and shifts fine. has anybody else have had issues like this also there is a service bulletin SI B 24 07 03 Automatic Transmissions April 2008 Technical Services that states similar problem but its only a 2 -30 sec's delay.

This Service Information bulletin supersedes SI B24 07 03 dated November 2004.

SUBJECT
GM5: Delayed P to D Engagement on Cold Start
MODEL
E46 with GM5: 325iA, 325xiA, 325xiTA, 330xiA from 10/02 up to 12/03
E46 with GM5: 325CiA, 325CicA, 330iA, 330CiA, 330CicA, 330i (HP), 325iTA from 03/03 up to 12/03
E53 X5 3.0iA with GM5 from 10/02 up to 12/03
SITUATION
The customer may complain of delayed P to D engagement (2 to 30 seconds) during the first cold start in the
morning.
CAUSE
Insufficient pressure boost for the C1 forward clutch during the first Park to Drive shift after extended
(overnight) parking.
CORRECTION
On a customer complaint basis only, reprogram the EGS control module using the "Manual entry"
Important:
It is not necessary to replace the automatic transmission for this type of complaint.
can anybody explain this?

I have all the same problems as the OP and some of the same issues as you. When your car went into limp mode did the light just comeon or did the car drive only in the limp mode gears? If the light just came on odd enough the air box wire the one that clips on can trip that light is what I come to find out . Look to see if that wire is loose! Otherwise it sounds like our reverse problems are the same smh "/ luckily my cargoes ino reverse sometimes!

I would stay away from any car with a trans issue. In fact, I'd just stay away from automatic cars altogether. Especially auto BMWs!

I can confirm TCC solenoid is the cause. Changed mine out, the trans is 100% fixed - never shifted better.

It was intimidating to screw with the tranny, but the DIY was surprisingly easy. I think it took me less than 2 hours! Writeup here:

I'm looking for a car for my parents (so it has to be auto), and I was thinking of an e39 5 series. It appears most of these use the ZF tranny. Is this problem likely enough to occur that I should just stay clear of any BMW with that tranny?

[QUOTE=neil1138;10638293]This doesnt apply to everyone! Please read carefully

Alright lets get started. A lot of threads have come up recently about no-reverse and such. Well something needs to be cleared up. At any rate, here's my story:

About 3 years ago, I bought my 2000 328Ci (automatic). I loved it, but one day I discovered that it wouldnt engage reverse. I used my trusty friend google and searched "bmw 3 series reverse gear wont engage" like any future fanatic would do. Well it led me to this site, I was told by many of you that it was my reverse drum in the transmission and that I was screwed. I mean, this could have been the case, but it wasnt. Here is the general breakdown of how E46s and transmission are distributed: A5S360R is the transmission we are looking for



323's - Mostly ZF transmission (Rare but can have GM tranny as well), the reverse drum actually shreds, causing you to lose reverse. This is the general and accepted idea of what happens. And it is true.

328's - GM transmission, (328s have the GM tranny). I have (well had) a GM tranny as I have a 328Ci. You could get under your car and check for a green label which is pictured further down the page, but I guarantee you that you have a GM tranny if you have a 328i/Ci

Now here's the main point: People will come on here sometimes and complain of no reverse, a normal situation to fanatics. But what they dont realize and what they dont notice is that the OP might just have a 328 and not a 323.

Here is why that's important: Automatic 323's are known to lose the reverse drum, that's a fact. Automatic 328s can lose reverse as well, that's a fact. But what's the crazy fact is that 328's with GM transmissions might not have actually lost the reverse drum! GM and ZF trannies both lose reverse gear but they do it in different ways. The drum failure is the common failure on the ZF transmissions. The symptoms of the 5L40E (GM tranny) are identical, you place the car in reverse and it revs up like in neutral and does not move. And that's the point of this thread. To show you what to do if you have a steptronic GM transmission.

So GM trannies might not have lost the reverse drum? Then what is the problem you ask? There are things called solenoids in the pan of a transmission that control pressure allowing the transmission to engage gears. We all know that automatic transmissions in E46s are hydraulically driven correct? Well one of those solenoids can go bad, and guess which one? The reverse solenoid. The name which you should call it as is the "TCC and PWM solenoid"

What happens: At any rate, what happens is when the car is cold, ect, this reverse solenoid has a mesh screen on it and build up can get on the screen causing it to not be able to control the pressure to the reverse gear. This in turn is when people notice the infamous "no-reverse." Thus, people with GM transmissions wont be able to engage reverse gear and they think that their reverse drum is to blame. This is not the case!

Here's some articles that explain a little bit about the TCC and PWM solenoid:

http://www.sonnax.com/tech-articles/TS6-MS-062-065.pdf

http://www.zoom-tech.com/downloads/s...s/gm/5l40e.pdf

http://www.automaticchoice.com/Catalogue/5l40e.pdf

Tell if you have a GM tranny: Bentley info and Transmission Charts (Important!)

http://www.automatikoelwechselsystem...skontrolle.pdf

http://www.taligentx.com/passat/main...ge/BMW_ATF.pdf

http://www.europeantransmissions.com...fluidchard.pdf

I experienced reverse failures with my GM transmission 3 years ago but after a little bit of research that long time ago, I found that my reverse gear actually hadn't shred.

This is how I found out: I couldnt engage reverse ok, so I put my car in Neutral and rolled it down my driveway, to where I was able to engage Drive. I drove around town for a little bit, maybe to clear up the mesh screen, and then I tried engaging reverse. Lo and Behold! My reverse engaged again! This was an on and off occurrence for me for years. I never decided to replace the solenoid because I didnt really care for it. If I ever lost reverse in a parking lot, I just waited for the car to warm up and shifted around a bit. Then reverse engaged itself again.

At any rate, if you are the owner of a car that is experiencing no reverse and you have a GM tranny, try and get your car out into the open and drive around for a bit then try and engage reverse. If it comes back to life, then your solenoid is to blame. If the reverse drum was really shredded, you wouldnt be able to engage reverse again. The solenoid is in the pan and only costs around $250 to fix (labor aside). So even if you arent sure, I'd say its worth a try.

Here is the part you need, Part #4 in the diagram. Reason I say it will cost $250 to fix is because you should get a new gasket and filter:

04 Pressure regulator,convert.lockup clutch 1 24327532013 $83.5

Gasket and filter:

02 Gasket, oil pan 1 24117524707 $36.19
06 Set oil filter 1 24117557070 $132.11



Little green marker on the side indicating a steptronic GM tranny:

Some pictures of the reverse solenoid:

DSC_0289

Reverse solenoid in the valve body

DSC_0306

Actual solenoid

DSC_0339

Screen that gets clogged

DSC_0340

I'm sorry I didnt post this 2 years ago.


Cliffs:

I think people with the GM trannies automatically associate the ZF transmission failure (reverse drum shredding) to their GM transmissions no-reverse even though the GM transmission has a completely different no reverse issue! I think most people just dont know the difference between a GM and a ZF tranny. Most take it to a shop saying they cant engage reverse so the shop just replaces the entire transmission when all that was needed was a solenoid! If you have a GM transmission and are afraid of losing reverse, when it happens, look into replacing the TCC & PWM solenoid. You don't need to replace your entire transmission!

This is just a possibility to look into, this doesnt apply to everyone!

(For anyone interested, my thread I made nearly 2 years ago)

http://forum.e46fanatics.com/showthr...&highlight=tcc

And my quote from that thread 2 years ago:



Cheers my friends




edit by B: changed some picture links as per PMed request from Neil[


this is why there is some confusion, my car is a 2001 325 i built in 09/2000 and suppose to have the zf tranny,but when i went under the car and found the marker on the back of the tranny with silver back ground with green color,but isnt the green color marker suppose to be the gm tranny and the blue marker the zf

look at the oil pan

GM has a symmetrical pan, its rounded front and back

ZF is asymmetrical and has a hexagon shape at the front

Selenoid failure

My problem also lies with one of those selenoids in the pan. Maybe someone can shed some light. It feels asif lock-up occurs in all the gears even at low speed. I have read somewhere that lock-up only happens at higher speeds and in top gear.

No reverse on 2001 330CI DINAN S3

HELP, I have 130k miles and I keep it in prestine condition. Out of the blue I could not reverse and get it out of parking spot after office. It does not start working ether after I drive it around for 30 min. After reading all your posts, I think it is not the solonoid issue. EurotechofHolland.com quoted 2500 for a rebuild of transmission and replacement of the drum. They will use OEM kit for it.

SharpBMW dealer in Grand rapids MI, does not rebuid transmissions but can replace it. He quoted 5-6k to get a remanufactured tranny for it.

I am still trying to rebuilt it and sell. what are my options.. Please dont let me down friends..........thanks

doing the fluid and solenoid replacement - shot in dark possibly

I have been reading these posts and others for the last 4 days. Went ahead and ordered the TCC solenoid, and will prepare the flush, fill, solenoid replacement soon.

I know by reading this, it works for some GM's, improves other, and doesn't help if the problem is in the valve body.

If it doesn't help, I will probably do a follow up flush and fill as I have read that has improved the improvement of successfully shifting with fewer no reverse issues (better odds)

Has anyone removed the valve body themselves... or if mine is still bad, should I order the rebuilt valve body and pay a transmission place to remove my old one and put the new one in.

I am pretty confident with auto work but limited to fluid, accessory, some suspension, tune ups, etc.

did step one, the flush/filter/fill

OK I did the fluid change and changed the filter.

Oil was black, and there was a little bit of shavings in the magnet area. About 5 quarts of fluid came out. I pumped in about 5 1/2 quarts, did the warm up, and undid the filler bolt.. nothing came out, so I added about another quart, and went through the shifting again. and it did start to flow out like the DIY said.

Took it for a test drive and it did not immediately shift into Reverse. Drove it around for about 5 minutes and it shifted into Reverse about 5 times in a row.

My plan is to drive around for a couple days, then drop the pan again and replace the solenoid. The write ups look like you have to drop the valve body a tad to get clearance to get out the solenoid. Hope that works out for me...

I am guessing the oil level was low to start with, but now I have the proper level.



UPDATE: With just the atf fluid change it has worked for 4 days without fail.
