328xi GM Transmission Replacement

yue0707 · 11-08-2019, 09:15 PM

Hello folks.

I was wondering do the GM transmissions from the RWD 328's have the
Same compatibility with the AWD models?

My trans is at 119k but it's starting to show signs of going south. I'm getting a drain, fill, and filter tomorrow (FCP Euro kit), but I've noticed slipping in first under hard acceleration and a slight tizzy in 3rd under normal acceleration.

I absolutely hate this "lifetime" fluid shit. Because dumb non mechanically inclined people actually believe it or just don't care and discard after 100k. If these things had 30-40k service intervals id have no doubt that they'd go beyond 200k.

Anywho if tomorrow brings good news I'll have time I guess to get a good deal on a
Replacement. My labor is heavily discounted with a euro tech shop I'm really close with so
I'm really only paying for the transmission.

it will be fine after the servicing.

mine had shudder and shift flares when I bought it at 100K, a full service and it was fine.
now at 150K and I'm going to change the fluid again.

GM recommends 50K for "severe duty" and 100 K for normal service.
I intend on doing the fluid every 50 and a filter/full service again at 100K.
