I just recently notice that my car is taking a bit longer to engage into reverse. It seems like there is a 2-3 second lag or so before it engages. Has anyone had this problem?

What is the year and model of your car? How many miles on the car/transmission?

When was the last time transmission was serviced (trans fluid/filter change)?

I have had this problem on other cars and solved it pretty simply. There are additives that you can put in the transmission fluid before changing it that will help clean out the transmission. Typically you will put the car in reverse and let it idle for ten minutes or so with the wheels stopped so it doesn't move. After doing this change the fluid and cances are your problem will be solved. This process helps restore pressure in the hydraulic systems that allow your transmission to shift.

Im not a big fan of addatives :thumbsdown:

At least yours does it in reverse. mine does it at long red lights on D!

It's only left in for the duration that you are flushing the transmission. You change the fluid right afterwards with your regular ATF. I'm not a huge fan either but this is much better than the alternative.

many of those additives cause your seals in the transmission to swell up.....which may restore some lost pressure. remember, auto transmissions are hydraulically operated.

Thanks I think I'll give this a try and see how it goes. Is there a particular brand/additive I should try?

I have a 2005 525i and when it stops, i guess when the gears switch from 2 to 1, i feel a little "kick". I took the car to the dealer, they did some kind of "reset". It didnt help though. They said that i should drive a little bit for the transmission to "learn" my driving habits. I think that was complete BS, and car still didnt learn.

Other people tell me that transmission is sealed and cannot be flushed. Does this mean i cant add any additives?

Dealer suggested to replace the transmission for like 6K.

I think there must be something i could do to fix this. And yes, mine takes longer to engage into reverse too.

Maybe in a '92 Pontiac ... but there isn't much that a $5 additive will to do to the package of "chemical stuff" that makes up the fluid inside BMWs auto transmissions. The problem may be something simple like a s/w fix or correction of a leak (there's a valve/gizmo on the transmissions that is a common problem area). In either case the cure isn't likely to be a magic elixir from Autozone but a diagnosis that pinpoints the real problem.

For the OP:

For starters I'd suggest trying the reset "technique" .. that's described in the forum - search for it. That will cause the adaptive feature of the transmission to re-learn how the car is driven. But if the problem is more severe and continues I guess you know that means a trip to a qualified BMW dealer or indy.

Maybe it will be something simple like low fluid level - that can be checked without taking the transmission down. Find what caused that - fix it ... top off fluid ... and pray

Good luck sorting it out !
