'95 525I transmission question

[bmarsh]

My '95 525I transmission(the GM tranny) has begun slipping in reverse but all the forward gears work fine. The dealer told me I need a new transmission but after talking to a shop in another city that knows BMW transmissions, I was told that it could just need a band adjustment. Could someone that has had some experience with this comment on whether this is true or not? Thanks for your help.

There is a TSB on this failure. It is a gasket that fails in the transmission. It looks like this when it happens:

The TSB is 24 05 94 "Pendulum Shifting, Delayed Engagement or Adapter Case Leak" BMW offers a repair kit for this failure, PN 24 27 1 423 311.

I have been down this road before on my old 95 525iA. I purchased an aftermarket rebuild kit and a friend and I rebuilt it in his garage. Everything inside the transmission at 145K miles was perfect except for those gaskets.

HTH.

Sorry for the bump, but my trans is taking about a second to engage reverse - all the forward gears are great. Once reverse engages, it's ok as well. Does this sound like the bad-gasket issue and if so, for someone that has rebuilt his share of engines, would this be a troublesome fix? I've never ventured into the inner-workings of a transmission....

I mean what level of nuts and bolts are there? (figurativly).

Is it just pull the tranny, crack the case, replace the seal, put together and replace into car?

Of are you taking stuff out of the transmission itself... like valves or things.

I don't konw anything about a transmission...but I think I could pull one and replace a gasket.

Need advice, mine is slipping in R a lot.

Thanks.
