I'm honestly still on the original mechatronic sleeve. + its always better to replace because it acts as a filter i think and filters the oil as its cycled thats what the cylinder looking this on the pan |

Any advice on how to get the mechatronic boot in? It just doesn't line up. Should I be pushing a little? I can get it in just enough to where only the orange seal is out. By than are the pins lined up? Or not yet. Any help appreciated. After taking forever to lock the sleeve into place patience is running dry.

this applies to 335xi
The 335xi involves many additional hours of swearing to replace the mechatronic sleeve. You have to remove the transfer axle or whatever it's called to get to the fill plug. There is no way to get to the mechatronic without removing or at least loosening the transmission mount. I could get the mechatronic out of the tranny but there wasn't space to get the damn thing out between the tranny and the tranny mount and hence, no space to get the new one in. The rear tranny mount requires removing the exhaust to get the damn thing back in. I could get the main bolt out with enough prying to get the mount off but haven't been able to get it lined up because the big bolt hits the exhaust. Spent about 6 hours on it tonight. Probably another 6 tomorrow. Just letting people with the 335xi know that it's a lot more trouble...

335xi update
got it all back together and tested at 100mph. Seems to work. Attached are some pics of the xi transfer axle and rear mount, which are in the way of doing this job.

New to the forum. Have a 2006 325i with about 40k miles that i dont drive very often and noticed a puddle of trans fluid on the garage floor under the middle of the car just like many of you. I just want to know TRUTHFULLY how difficult this job is. Mainly because the STEALERSHIP quoted about $800 to replace the pan/filter and the mechatronics sleeve. So again how difficult is this DIY job? Thanks in advance for any replies!
P.S. I have an electrical engineering degree so I'm decent when it comes to fixing things. I've also changed the oil myself on this car if that helps in comparison... |

get break cleaner or parts cleaner, go under the car spray the sleeve and all around the pan check again in a day or every day for week to determine where its leaking from, but if your gonna do the pan might as well do the sleeve.

Great DIY! Question, if not replacing the pan do you have to pump any old fluid out or will it all drain out? Looked like by the pan design you have to pump some out....was any fluids left in the pan when you removed it?

i honestly wouldn't use anything other than oem, just because the power levels we are at LOL thats just me i scored $15 a quart from the guy above for the fluid overhaul on the trans I'm installing this week. i got 9 and had 2 leftover so that should be plenty yeah it adds up :| i think there is a guy in the for sale section selling 7 quarts for $125 talk him down or give best offer. don't cheap out on tranny fluid the transmissions are reallllllyyy specific! |
