Tranny!

If by using the cheap ATF DextronIII,I have to change it every 3months?or if ever I could go longer whats the max I could go before I have to change?still speaking of the safe side though...

Well better not talk about months but about miles or kms.
Honestly, I have not enough experience.
I am driving 10 k km per year and change it every year, but for sure every 2 years would also be o.k. I just have a look at the oil how it looks.
My friend has another E32 750, he drives 40-50 k per year for business.
He is changing every 6 month these about 3 litres which come out. Let's say all is changed then in 2 changes and 50 k km.

The original fluid I had inside from BMW I changed the first time after 120 k km, still looked fine.
I am not a tranny expert, but what I read they recommend it after 60 k or so, but that also depends on driving conditions.
Remember, once BMW talked about lifetime tranny fluid.

Mabye you google a bit and find recommedations.

Here in the Corvette Forum they mention 30-40 k miles invervals accdg to ZF

That might be a good idea.


BTW: as engine oil I use Fuchs Titan from Germany

thanks..big help:D

I think the filter O-ring is bad or too small. Change the oring to the thicker one. Refilling is NOT done when COLD. It is actually done in warm transmission. With car running in idle... keep filling until fluids come back out... and then that's done.

the filter, oring or fluid level or a combination of all of the above. Here is the bulletin and part numbers.

I replaced the fluid with Penzoil Muti-ATF and it used 8 quarts. I will just live with this, I love this car. any ideas on what else I may have to do?

I did notice the next day after the fluid change, there was a small leak of tranny fluid (very small amount) coming from where you add the fluid. Call the shop and the mechanic said to watch this a few days and if there is still a leak to bring the car back, also he said the he used the old seal or gasket from the fill plug. I will be taking the car back monday to see if we can take care of this, also the message about the whine I left this in the car with the filter and fluid so the mechanic could see. He said he could tighten the fill plug some more. I'm concern if the leak maybe the cause of the cold whine and would it be a good idea to drop the pan/oil again with less than a 100 miles on the maintanance. like I mention this is the original BMW filter kit with a extra o-ring I ordered.

Hey Roderick,

Not trying to hijack your thread, but I have noticed the same whine after changing mine. Have you also had any upshifting issues? When I stomp on it to kick it down to pass or get on the expresway, it does not upshift back when I let off the throttle. I have to take my foot off the pedal, put it in "N", let the revs settle down then back to "D" for it to upshift. Yes, I know this is bad to do, but I'm only trying to diagnose it. Anyone else have any ideas? Fluid level?

What fluid did you use? I suspect you got the same O-ring problem.

Tiger,

I used Amsoil Universal ATF. It is a full synthetic and compatible with LA2634. I also used the BMW filter kit, ordered from the dealer. Filtran filter, new bolts, o-ring.

I still suspect the o-ring since you got a whine after you installed new filter and you didn't have the whine before. Was the tranny topped out while running? Could be low fluid.
