So no one has put a finger on the root cause of the no reverse fiasco?

My tranny is acting really funny.

When I engage reverse with my foot is still on the brake, the rpms bounce really low (500-700) and the car shakes. Occasionally, this kills the engine but not all the time. Once you gas it, it slips and the rpm rises (like in neutral) but engages almost immediately after that and reverses but the shaking and jerking is still there and you can really feel the slip.

In Drive, the shifting is harsh in low rpms and smooth in high revs. By harsh I mean that when I gas it in drive, the rpm drops, then the car feels heavy (loss of power), and then rpm rises again regaining power. What I don't understand is it's fine when you drive it hard (high rpm, In forward).

Please help. I'm desperate to get this fixed...

Please?

I am having this problem. I took it to a mechanic to have the fluid and filter changed. Afterwards the forward shifting seems better but the reverse may be worse. Before it was shifting in reverse usually after warming up. Now it shifts into reverse for a few seconds then I have to put it in neutral and then back in to reverse a few times to get it to back up. Is my problem the same as the one listed here? Also, I went to the noreverse site and there was a guy I talked to in San Diego that said he fixes this problem if you send the valve body to him. It doesn't sound like its cheaper than replacing the valve body from what I've read here and the linked posts. Any info greatly appreciated. Also, when the car shifts from 3 to 4 it drops to 5 and doesn't shift back down to 3 very easily, especially when going up a hill. Could this be because of too much fluid or something else? Thanks again.

To Summarize,

The problem is in the Valve Body. That is for 100% sure.

Reverse is not engaging most likely due to the Reverse Lockout Bore not engaging. Several things can keep this from happening.

So far the TCC module replacement has not fixed anyone's problem in the long term.


Flushing the fluid is good for the transmission and will make it shift better overall.


Getting your Valve Body repaired (300-500 ish) or getting a new one (1200) might be the only true, long term fix.

Or if we could learn how to repair the Valve Body ourselves we would be best off.

You donot have a G5M transmssion, this is unrelated to the thread, might be your reverse drum.

It has been a while since I was here. I have the GM tranmsission in my 323 with a build date of July 99. I got a great price on the car because the seller was convinced it needed a tranmission, I followed the recommendations of this thread and decided that I needed the TCC Solenoid. I'm actually a pretty good mechanic, but I haven't the guts to cut into a transmission and start screwing around. To be honest, my main issue is filling it with properly when the new parts are installed. Maybe filling the transmission isn't hard, but the directions look difficult and I don't have the proper equipment to get under a car without laying flat on my back.

Anyway, sorry for the digression. I took the car to my mechanic specifically for the TCC. He said that when he dropped the pan, it was dirty but that the TCC was okay. I don't know how he could surmise that, but I went along with him. The car worked fine for weeks, but the problem eventually returned. My daughter drives the car, and she reports that the transmission fails about 10% of the time, and there's no pattern as to always cold or always hot. Reverse balks at any time with no rhyme or reason.

I took the car back and got the fluid flushed for free and paid for the TCC. We got the car back on July 15 with a new TCC and 6 quarts of ATF. I paid for the fluid and the part, the mechanic covered the labor because he didn't put the part in when I asked.

I'll keep tabs and post back.

Basically, I hit a bases loaded home run on buying the car unless I have to do major transmission work -- and then I only hit a single that didn't bring anybody home.

Is it truth that changing tranny fluid can mess up the tranny. BMW has the "lifetime" fluid.

Yeah I've read about failed tranny after fluid change.

I aint touching my lifetime fluid with a ten foot pole unless fluid level is low.
Since it's a sealed unit, the synthetic fluid has no where to go unless there's obvious leakage. If so,I'll fix the leak and top up with fluid.
Since I drive an auto and dont abuse the car, there is no chance of grinding the gears or shaved metals. Therefore, as far as tranny mechanicals is concerned, my tranny will infinitely last a long long time.

If Im gonna have tranny issues, it's gonna be in the tranny electronics.

My transmission is GM A5S 390R. I'm having the manual swap done. The good thing about the manual is that it only holds 2 quarts of fluid and from what I can tell doesn't have a filter. This will cut down on maintenance.

I followed the advice of Starless in this thread http://www.bimmerfest.com/forums/sho...d.php?t=458451 and had a rebuilt valve body with sonnax kits installed (after the solenoid fix failed). Now all is well!

It appears the valve body going bad is root cause for some people. So what makes the valve body go bad. Improper tranny oil change procedure (hehe) or just bad luck?

What tranny does my A/T 325Ci have? I noticed you pointed out what transmission type the 323 and 328's have, but not the 325... And is the 325Ci prone to these issues?

You have to back-read or read from the top of this thread. There's a guide somewhere . Heck it took me 2 days to read from page1

And the person who pm'd me basically asking the same question, find the guide somewhere in this thread. Look for Neil's post.

Could you please elaborate? What shop did you use? How much did it cost? What is the sonnax kit?

I will be getting my transmission valve body repaired after a short while, and no one is reporting back with the results. Starless's thread just said it works, doesnt say how much, where, etc.

Let me know and thanks

Wow. This is the solution to fix the GM trans no reverse due to faulty valve body.

http://www.bimmerfest.com/forums/sho...d.php?t=458451


Long story short;

Option 1: you can spend $700 for the tools and parts to fix it yourself (Sonnex Kit + Tools)
Option 2: Spend $500 to ship it off to a professional shop that will install the Sonnex kit for you
Option 3: Buy a re-manufactured one for around $500


So your thinking, what do I need to do?

1. Put your car on 4 jack stands
2. Drain Transmission
3. Remove Transmission Pan
4. Remove Valve Body
5. Ship Valve Body to a shop or Install re-manufactured one. (Needs to be Sonnex capable)
6. Wait for 1-2 weeks (not if you choose remanufactored)
7. Reinstall

I am guessing it will costs 700$ all said and done. Shipping will be 30$ each way, and the fluid is 100$.

That's great! How many clicks on the odo? Aside from checking for leaks or fluid level, I wouldnt touch (tranny oil change ) that tranny if I were you. If you do, make sure it's done right. But if I were you I wont do it.

Thanks toad21 for the post. The dealer is recommending I change my valve body since they think replacing will fix my problem 100%.

The only problem is they need to charge me $3,000 for the new valve body from germany and another $1000 for labor. They must be out of their freaking minds.

So I have contacted the seller of the remanufactured valve body from the link you posted. Hoping to get a reply soon.

Thanks man.
