installed new zf pan and now car won't go into any gear

itechteam · Yesterday, 09:02 PM

2010 BMW 335i M, stage 2+ tune. I drained the transmission fluid dropped the zf pan, installed new pan and put in about 5 quarts of fluid. That's all it would take till I warm it up. While I was warming it up, I wanted to move it back some but it wouldn't go into reverse, or drive?

Do I have to do a trans reset or something? I didn't mess with anything else other than new pan and fluid?

What are your thoughts?

So after it was warmed up did you top it off, sorry was not clear on your question.
What fluid did you use?

You shouldn't have to do a trans reset at all.
Did you get it up to temp and then run through all the gears and top off after that?
That's basically the ZF process.
