transmission help please!!!!
Looking for some help, advice, solution anything really i would appreciate anything. im new to BMW so please bare with me if i sound like a complete idiot! i have a 1998 BMW 328i and everything is great except for the transmission. Its an automatic and it shifts perfectly fine from a stop through all the gears except from 2nd to 3rd from 2 to 3 it jerks really hard. as for the slowing down when it down shifts im not able to place it :dunno: but it does the same when it down shifts from 3 to 2 and on ocasion it also does it from 2 to 1. now from a dead stop if i floor it it shift really hard through all the gears except 1 to 2. the transmisson light IS on in the dash and i have checked the fluid level and decided to do a service on the transmission. i drained the fluid changed the trans filter, new trans pan seal, and put the approved trans fluid in and made sure it was the right level/amount. im very good mechanically with cars/trucks and can do almost anything to/with cars and trucks, but BMW's elude me cause there a vehicle im not at all familiar with. please help me out yall this is my first BMW ever and i really want to experiance it for what it really is!! thanks:thumbup:

Welcome to the fest!

First off, that manual transmission switch is NOT for manually shifting the gears! It's strictly for locking the transmission in the gear it's presently in (such as 2nd) if you encounter poor traction. It keeps the transmission from up-shifting and then downshifting again when traction is regained. DO NOT push the "M" button and then run the car through the gears with the shift lever. BMW automatics are notoriously weak in the E36s, and manual shifting one will rapidly hasten it's demise. Read your owner's manual. The transmission should be operated in the "D" position or "3" for more rapid acceleration and then shifted into "D". Running it in "3" raises the shift points so the car has better acceleration.

For your problem, I'd say a fluid and filter change might help, but it really sounds like it may be a transmission computer problem OR the valve body misbehaving. The automatic transmissions in our E36s are French-built GM transmissions. Repair of them is pretty much beyond the ability of most of us. You need to have the transmission codes read by an independent BMW repair shop, or as last resort, a BMW dealership. By your description of the shifting, it is bound to have some error codes stored. Good luck.

sounds like overrun piston seal rolled into piston bore or the second gear drum has a grove cut into it from hammer shifting controlled by car

Transmission Hard Shifting
Ok I hear how some people are having trouble with hard shifting in the tranny well I had the same problem. Forever I couldn't figure it out it was shifting hard from 2nd to 3rd and through all the gears when I floor it! Well, I could tell it was a sensor issue but of course WHAT sensor is it?! Try the MAF sensor cause I swapped the MAF sensor with a new one and it solved EVERYTHING even the check engine light!!!:banana:
