E34 Automatic Trasnsmission Charactaristics

I have added a second E34 to my arsenal of automobiles. It is in GREAT shape, but I have a question about the automatic transmission. This is my first E34 with an automatic, so I'm unsure of how it is supposed to act!! This is what it does...

1) When first driving, i'm assuming the automatic transmission fluid is cold... the shift from 1st to 2nd is delayed. When coming to a stop in the "cold" state, the transmission does not want to shift down when it seems it should. Engine sounds a bit labored until it finally shifts.

2) Shifting in general when it is going from gear to gear is quick, but it seems to be a bit hard. You can feel it when you speed up in a moderate fashion. I do not think there is any slipping. The RPM just drops down as it should.. it does NOT peak up quickly or anything that might suggest slipping.

3) When doing a high performance accelleration, I dont seem to have any issue with shifting at all.

4) On occasion, when i'm accellerating from a stop, i hear a short sound that is hard to describe, except perhaps for that of a fart! It kind of makes a quick pfffft sound. While it is doing that, the RPM doesnt change, but it seems there isnt much power.

ANy thoughts???

I think the shifting characteris, when cold, are designed to warm up the engine quicker for emissons reasons. I know GM made 4-speed auto shifts differently before it warms to operating temperatures.

Yes, I think it mentions that in the manual that the transmission will shift at a higher point when the engine is cold to bring it to operating temperature faster.

The engine is not at operating temperatures on a "cold" start at 70 degrees.

Are you suggesting mixing these two fluids together in lieu of the BMW OEM fluid? I'm assuming its for cost reasons. Unless I'm looking at this wrong, its somewhere in the neighborhood of $150 for transmission fluid from BMW! Geeezz...

I've been using Pennzoil Multi-Vehicle ATF in my transmission (5hp30) with no ill effects for 100K miles. I think it costs about $4 a quart.

Several other major-label ATFs also claim to be compatible with Shell LA2634 and/or Esso LT71141. Just check the back of the bottle.

You can also go with one of the premium synthetics like Amsoil or Red Line D4. I had a BMW-savvy independent to a drain/filter/fill on my 540i about 18 months ago, and he used Eneos synthetic, a premium Japanese fluid. I think I noticed a slightly smoother torque converter lockup afterward, but it could have been a placebo effect.

I might sound pathetic with all my questions, but I see a lot of different ATF filter kits too. I dont want to get the wrong one, and find i'm short one seal and have my pan open for 4 more days because I had to order another seal and waiting for a seal to arrive. Also a wide variation of costs. I'm looking for a good USA sourced kit or parts list that wont break the bank, but will last me 100k mi. Advice? Thanks!

The d4atf is for the transmission. The 75w-90 is for the differential. In regards to the filter kit, you can't fk it up if you specify the make and year of your car on bavauto, bmaparts, rockauto, or autohausaz.com. They are all US companies.

If you are doing this yourself, get a bentley manual, post your email address, or search the forums. There are pictures of how to do it. As far as breaking the bank, I don't know what bank you have. But I know a bank would be less full if you were purchasing a new transmission because the old one siezed.

Martinav, your profile lists a 1995 540i. If the car in question is a 540i with automatic, I would offer this advice:

Stay away from aftermarket transmission filters. They're notorious for collapsing and impeding fluid flow. Instead, get a BMW filter from the dealer or from an authorized ZF parts dealer like Eriksson Industries. The filter should have the word "Filtran" embossed on the plastic housing. The BMW part number is 24341422419.

The correct filter is about $50 -- not cheap. But you can use the money you save by not refilling with the expensive BMW fluid.

There are a number of pictoral blow-by-blow instructions online offering tips on doing a fluid and filter change that will turn up with a quick google search -- again, if the car in question is a 540i. Since you referred to BMW fluid in a prior post, I'm assuming it is.

Thanks for your ehlp. I'm assuming this kit will have EVERYTHING I need to do the job. Yes?

Ebay Auction Here

Yep, that's it. Pan gasket, filter, o-ring, mounting screws. You may not need the pan gasket, but it's good insurance to have one on hand.
