In this video I walk you guys through the process of dropping your E9X manual transmission at home on some jack stands! The car I'm working on is a 2009 BMW 335i, but this process should be more or less the same on any other E9X 335i (N54 or N55), and should be nearly the same for all of the E9Xs powertrains.

While the trans is out of the car, I replace the N54's rear main seal, the input shaft seal on the transmission, and the shift selector rod seal on the back of the transmission. Other good things to replace during this job aside from all the clutch components are the giubo (flex disc) and transmission mounts, along with downpipe gaskets and hardware.
My car had a clutch disengagement issue which led to me needing to drop this transmission, despite only having around 15k miles on the clutch since I manual swapped the car in April 2020. Turns out I needed to replace the clutch, as mine seems like it failed prematurely with the spring coming out. It also seems like the clutch didn't properly match the pressure plate it came with, but the new part I received was correct. All of this combined with my failed pilot bearing and throwout bearing meant it was time for a full refresh. I will be making a separate video altogether dedicated to diagnosing my transmission issue, and what I think went wrong. Hopefully this video helps you with your transmission work!
