Has anyone used Seafoam Trans Tune in there Automatic transmission acting up.
Has anyone used Seafoam Trans Tune or something like that in there transmission. I am having a problem with it not wanting to move when it is cold(Minnesota 15 degrees) and has not been run (over night), It will move slow and revs fast. Once that happens, transmission comes out of the breather. If you start it and let it warm up for 10-15 minutes it works great, shifts very smooth. I have done a fluid change since it happened and worked twice and is now doing it again. It's a 2000 BMW 323ci, steptronic Automatic transmission 153,000 miles.

Engine heater on the tranny. 15 is cold!

Sounds like "Delayed P [Park] to D [Drive] Engagement on Cold Start.'' Unfavorable tolerances of C1 clutch housing causing internal transmission pressure leak after extended parking.''
Letting it warm up is the path of least financial resistance.

It's normal what you are experiencing

Mine has been doing it since new pretty much.

Just need to let it warm up first.

I would not use that stuff, particularly if you have a ZF transmission. You would be better off just getting new, propper fluid and filter in there, and warming it up a bit, as mentioned above.
If you want to get the propper trans fluid for a ZF transmission, get it from the dealer, but I have read that some dealers don't even carry that fluid any more.
This place is a great source for ZF Fluid, since it is the actual fluid ZF reccomends And sells for their transmissions. It is also cheaper than the dealer, and cheaper than the "equivalent" fluids, which are really not equivalent. Check out the reference chart, to make sure the fluid listed in the link is the correct one for your transmission.

wants to use seamonkeys because tranny fluid is thick

I have a GM built transmission which takes Dextron III or above according to the BMW dealership. I used in the past Valvoline Max Life DexIII/Merc Fluid. I was thinking since it seems like something may be clogged because fluid is pushed out of the breather that Trans Tune may clean some of the deposits off of the screens on the control valves, solenoid screens, Etc. Some people have told me that the control valves may be sticking. Since I only have 50 or so miles on the last trans fluid change, and since I have leaked about a half quart I was going to add Trans Tune, drive it around for 5 miles as the directions say and do a filter and fluid change. Refilling it back up with about 6 quarts of Fluid

The product says
Safely cleans components. Does NOT harm or swell seals. Does NOT alter the viscosity of the transmission fluid. Reduces rough or erratic shifting. Removes damaging moisture. For Automatic Transmissions. TRANS TUNE reduces rough or erratic shifting by dissolving varnish that contaminates transmission valve bodies, bands, governors, pumps and passages. TRANS-TUNE makes the perfect system flush for transmissions,

Update on steptronic transmission
Hi Guys,

Here is an update on my transmission. Last week on Wednesday I warmed up my transmission so I could move it. I decided to try Trans Tune, made by seafoam since I figured at this point it couldn't hurt a already messed up trans. Here is what I did. Warmed it up for about 20 minutes, jacked up and opened the fill hole, since the fluid was up to operating temp it had expanded and so I was able to let out about a half quart of fluid out. Letting the car cool over night and the next morning I started it and added about a half quart of trans tune to the fluid. According to the can it cleans valves, screens etc. I proceeded to drive the car about 20 or so miles, came home, jacked it up and drained the fluid. It seemed to be a bit darker in color from the day before. I then did a new filter and pan gasket and filled it up with valvoline max life semi syn fluid and a 1/4 quart of Trans tune. Topped it off while running the engine. I have driven the car 3 times since and moves when it is cold and it shifts perfectly. It seems like it may have had a clogged solenoid screen or something in the valves. Hope it keeps up like this.

Please report back in a week or so with continued results!

So far my transmission still works Week 2
Here is what worked for me on my GM 5L40E Steptronic Transmission, It has been a good 2 weeks since I did this on my transmission and now it is working great and maybe better than it use to when I purchased it a year and a half ago.

1.) I did a fluid drain and fill, Follow the fill instruction for BMW transmissions, warmed up the transmission for about 10-15 Minutes, drove the car for 15-20 Miles. Let the car cool over night and put it on jack stands.
2.) Next day, with the engine cold. Removed the fill plug and drained out about Ĺ quart of fluid and put the fill plug back in. Take a bottle of Trans Tune made by Sea Foam and a pump. Trans tune is designed to clean valves & screens, and the inner workings of the transmission as well as it takes moisture out of the fluid. Start the car and unscrew the fill plug, fill up the transmission with as much Trans Tune you can put in, screw in the plug, slowly run through the gears. Warm up the car again for 10-15 minutes and drive it around for 20 miles or so.
3.) Put the car up on jack stands, you may want to wait for it to cool a little so you donít burn your hands, drain the transmission fluid, remove the pan and pull the filter, Make sure you clean off the magnet in the pan. After pulling the filter down check to see if there are any rubber gaskets stuck in the hole. If so remove them. Install the pan and gasket. Fill the transmission and add a ľ bottle of Trans Tune while you are filling it up. Start the car and fill up the remaining amount with transmission fluid.

Hopefully it will work for you. It did for me. I had done a transmission fluid and filter change one year before and put on about 10k then this happened. Thinking back I should have done another fluid change to get all the old fluid out. Looking back at the fluid it was very dark since I donít think that it had been done for quite a while. When I changed it this go around it looked more like Tea color the first time, doing the fluid change, second time it looked better and now it looks pink.

I used Volvoline Max Life Dex/Merc, I have heard good thing about this fluid.
Its $6-7 a quart at OíReilly auto, Autozone has a Gallon (4 Quarts) for $15.99, Better deal. Each fluid change is about 6-7 Quarts
Filter and pan gasket part #FK353 are $24.99 at OíReilly Auto, only differences is the Gasket is all rubber compared to and original which is rubber and Metal. Just don't use gasket sealer on a rubber gasket or it will leak.

Good Luck and I hope it works for you!

Gusser1 I posted this at Bimmerfest Pls reply if you can thx
Hi Gussers, I have a similar problem with my 2000 528i with the same trany It's been a real intermittent problem at times. What it's doing is leaking fluid from the breather like yours. The difference is I don't have any problems with shifting Fwd or Rev, and no slipping. About 6 months ago my son noticed the problem with oil in his garage. He took to his mechanic who couldn't find anything so he, did a trany service. Then my son gave me the car. Had it parked in driveway and it did it's leaking about 4 times in one week. So I found what you did, with the breather leaking. So I read alot about how to drain and fill trans. I took it back to the mechanic that did the work. He opened up the fill hole, while it was runing, and it really poured out. So I had him remove some fluid until it was a small stream like it's suppose to be. Well I had the car up on some ramps last night to bleed the coolant. Then today in the morning backed the car down and sure enough the breather leaked again. It had went 16 days without leaking (400 miles). So now trying to figure out what to do next. I like what you tried. I might do the same. So how many miles are on the trany since you did the oil change? Did you leave the Seafoam tuner in? Does it say you can? I also read somewhere about using the trans Max life, and people seem to like it. Any other thoughts.

Gussers1 05-22-2013 10:24 AM

River jamie, I would suggest you do a transmission pan drop and new filter. It sounds like your filter maybe clogged. Some have a felt style filter inside the the metal filter housing. They have a higher ability to filter out things thus getting dirty faster. Some of the cheap filters only have a very thin mesh style filter. I would stick with a decent quality filter.

Recently I saw this on an older 92 fox body Mustang that had not had the automatic transmission fluid changed in about 7-8 years. Similar problem to you. It had a Wix filter that is on the higher end of the options. Fluid was still fairly clean. I had bought two filters, one was the store brand which looked similar to what looked like the original ford. The wix looked much better. Anyway, did a pan drop and cheap filter, filled and warmed up and drove. Parked it cooled down and did the same with the wix, new fluid again.

No leaks and shifts properly now.

Thanks for replying but does your BMW that had the problem like mine, still run okay? As I said, my ran for 16 days with no problem, then it leaked out of the breather again. It seems that it does it when its cold and in reverse. Is your BMW that was leaking out the breather still okay, no leaks, and how many miles?

Thanks again

coming out of the breather? the transmission is overheating?
something is clogged up.

riverjamie 05-22-2013 11:05 AM

Jason, thx for replying. I thinks it's more of a clog, because it seems to be when it's cold and going into reverse. But it's so dam intermittent. Gusser1 said that he put in Seafoam Trans Tune then did a fluid change. After seemed to be okay. He replied back to me, but wasn't clear to me if his BMW is still okay or not? And milage. It's been I think at least 2 months since he did the fluid change? So hoping he'll get back again.


Gussers1 05-22-2013 11:30 AM

My transmission is still working excellent! I'm very happy for that. So far I've put about 2600 miles on it and a advanced driving track day on it. It didn't miss a beat and still works great. I did use the trans tune in it and I was happy with the results. I followed the cans instructions. How long has it been since you replaced your fluid or done a pan drop trans fluid change? I had done a regular pan drop 1 year prior to having the problems. So i still had over half the original fluid from bmw. Since you only get a little over a 1/3rd of the fluid out, I did what I posted on the top to hopefully get most of the fluid changed. I also used Max Life fluid in the tranny. I liked that it was a semi synthetic fluid compared to others out there and it's a fair price if you can find it in the gallon jugs. Make sure you have the gm built tranny, otherwise I'm not sure what type of fluid you need. I would defiantly change the filter and when you have the pan off make sure you clean the magnet on the pan off. There will be stuff on it. It's not a hard job it's just messy. Sounds like you are doing your homework. I would suggest not driving the car until you do the fluid changes because you don't want to run the trans with low fluid. If it leaks fluid out of the breather when cold you more than likely have a clog. Let me know how it goes and keep us up to date.

riverjamie 05-22-2013 11:56 AM

Gusser1 Originally the AFT service was done at 113k now the car has 117k. There's a Green Metal tag on the side of the Trany that said GM with other numbers, also when I go to Realoem, and put in the Vin it comes up with A5S360r/A5S390r which is the same a 5L40e.

I believe it was over filled. I drove it back about 18 days ago, first thing in the morning, about 8 miles to the mechanic that did the service and had him open the fill plug, while engine was running, so I think the car was in the 86-122F temp range for checking. It really poured out. We drained it down until it was a small stream, like it's suppose to be. Then it went 16 days with no leaking out of the breather. Yesterday morning it leaked from the breather. This morning cold in reverse it did not leak. There are no slipping or shifting problems in FWD or Rev. I'm thinking trying your procedure and see what happens. It would be a lot easier to troubleshoot if it would do it more frequently.

Well today added the SeaFoam Trans Tune 8oz. at 117302. I did notice that the Pentosin ATF1 looked very dark only after 4K. I don't know what it looked like when it was change at 113K? So can only take the mechanic's word the it was changed? I called Pentosin they said that the ATF1 should be Amber and translucent. Well it look like neither. So going to run the SeaFoam then do a purge, install new fluid (Valvoline MaxLife and filter. I watched a good Youtube video by some German guys on how to purge the system by disconnecting the return cooler line and pumping the fluid out through it, then refilling the trany, after about three times the fluid looked pretty good. So hope that will work for me? Also has anyone used the Pentosin ATF1 product? Do you know if it turns to a dark brown in a short time, like 4K?
