Question about BMW 325
I have a 1992 325i automatic, that over the past 2 months the tranny has gone all sluggish. The car was lost a lot of it's speed and the kick down acellerator wasn;t up to much anymore.
I had a tranny oil change, new gasket and filter. The car is now almost as fast as I used to be and shifts like a champeon when the tranny is hot.
But, the tranny when cold takes time to change gear. Sometimes the engine passes it's rpm range when the tranny should change then slams into gear, also when I brake hard it goes into nuetral and if the engine is reving slightly more then idle speed it slams into first with a lurch. If I stop suddenly I have to stop all together and wait for it to change back into first so it doesn't slam back into gear. Very annoying.!
Any ideas guys?
At that age its a rebuild or re manufactured unit. I'll be expensive. Probably more cost effective to replace car.

SOURCE: Hard down shifts
Check the transmission fluid level, see if there is any foaming in the fluid which is bad, and condition, If the fluid is low the transmission fluid pressure could be low and if the transmission fluid filter is dirty, that could also be restricted the fluid flow.
The transmission fluid should be bright red like strawberry in colour, if it's dark like burgundy then it's time to change the transmission oil and filter. The hard down shifting could be a servo that is sticking caused by dirt in the fluid, have a Transmission shop service the transmission and scan the car's ECM for any codes that may be causing your shifting problem.
Good luck and hope this helps.
