Attention Auto tranny owners over 60K miles - BMW 3-Series (E90 E92) Forum

Turkeybaster115 · 05-07-2011, 10:50 PM

I began slowly leaking tranny fluid right around this mileage. I'm currently at 82K, and the other day, I had my car parked for 3-days straight, when I noticed a small puddle of trans fluid. I did some research on the boards, and its not a matter of if you'll develop this issue, its when. Leaking trans fluid can be scary, as it can lead to lack of gear lubrication, and clutch pack failure. The mechatronic sealing sleeve, and transmission pan gasket, needs to be changed, a long with a full liter of trans fluid for top off. I had the service done today at my local shop, and purchased the parts and fluid online. Get yours done today, weather you see a leak or not!

Trans fluid = Liquid Gold! $$

I changed mine(pan, sealing adapter, and 6.5 quarts of lifeguard 6) at around 45k miles. It might be a placebo but I felt like it shifted better and was smoother.

I think I am going to do this along with spark plugs, cleaning valves with intake off, power steering fluid, and rear end fluid every 40k miles.

Mechatronic sealing sleeve replaced at 33k miles. Like OP stated, trans fluid leak noticable when the car hasn't been driven for a few days/weeks. btw, the trans fluid looks like motor oil, not the usual red atf.

Great write up, I will do this next week!

kfrazie1 · 05-16-2011, 09:53 PM

glad to see my thread helped out.

Mine start leaking around 30k miles

! replaced both Mechatronic sealing sleeve and the pan. Changed the Trans fluid together, but I am using the ZF ATF fluid.

enrita · 05-17-2011, 12:23 AM

where did yo buy the fluid online?
Why didnt you just replaced all the fluid ? When i changed the pan 6-7 liters were needed.

All the fluid? Unless you are pumping it out of the torque converter you are only going to get around 6 quarts out with a simple drain.

AutohausAZ sources the fluid OP is using.

BTW mine leaked at 60k miles. Sleeve replaced by dealer, pan replaced by me.

RR80 · 05-17-2011, 01:11 AM

I just drain the fluid out and fill in the fluid til the pan can't take anymore. it's about 5 liter~~! It will hurt the trans if you fill too much fluid!

Car needs to be on and fluid at proper temp to fill it properly.

Yes, the car is on when I fill it up. Is that all ATF fluid are good on our trans? I use the ZF fluid because dealer use this fluid!

There are several threads about ATF selection in the Maintenance Section.

How much does the mechatronic sealing sleeve cost?

Magic-Man · 06-29-2011, 08:11 AM

This should be covered under CPO warranty, no?

enrita · 06-29-2011, 09:02 AM

yes of course. on realoem you can find prices of everything. you can also find most of the stuff on ebay.

BlueLion · 06-29-2011, 09:17 AM

had mine replaced two weeks ago at 56k.

Mr_SDP · 02-09-2013, 03:09 PM

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 $700 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...

Wes335XI · 02-09-2013, 06:44 PM

Had mine done back at 38,000 miles. Had a leaking tranny and rear differential. Everything done under warranty.

soldado331 · 02-13-2013, 12:17 PM

i hadn't heard about the mechatronic sleeve and it being a good thing to change along with trans fluid service. thanks for the heads up OP. added to my project list.
