Default Re: Transmission Swap Difficulty (SMG)

I did my clutch in my garage on jackstands. What a nightmare.

You need 4ft of extensions, some bolts needed a swivel socket for me. It's not impossible but it sucks a lot. Maybe if I had bigger jackstands and put it way up in the air it would have been better, but I don't think I would attempt it again without a lift.

There are some places that will rent you a lift, that might be worth looking into. Are you planning on pulling that trans off without changing the clutch or rear main seal or anything else? No better time to get that stuff done.

I've had the pleasure of pulling the transmission 5 times this year. Between dealing with SMG, clutch issues and finally converting to 6mt I've had a lot of practice. It's a pain but if you aren't trying to do it all in 1 day it's not terrible. I've found the bendable ratcheting wrenches useful for the torx bolts by the starter and behind the valve cover. I also used the harbor freight engine brace to tilt the front of the engine up.

I had that all replaced 20K miles ago, so I won't be touching them. However, I've been having an oil leak that's not coming from the CPV, so I'll take a look at the RMS.

Yea, I got plenty of time. I still need to confirm it's my transmission. The dealer did note both my struts were bent and the strut mounts need to be replaced. Maybe that could be causing this strange noise. It may be just another issue I have to deal with.

Just picked my car back up from the dealer. What a thrill it was riding back in one. Shifts great, just the whiny noise is annoying. Think I'll add more tranny fluid to see if this makes any difference.

I only needed a swivel on the big bell housing bolt at 2 o'clock position, the rest you can get out with straight extensions.

Either use jack/wood in front on engine mount arm or borrow an engine support bar (goes across front fenders) to tilt engine/tranny backwards.

Does the intake manifold need to be removed for the starter bolts?

Topping off with tranny fluid had no affect on the sound =(

I think a lot of guys dont, but for me to tilt the engine back enough to get a straight shot with the extensions, I took it off. It's easy and quick (after you do it a couple times ).

Removing the airbox on this car is a lot easier than removing manifolds on other cars. It'll make doing the starter bolts easier

Edit: Though I just noticed the thread isn't about replacing a starter ><. If you're under the car anyway, you shouldn't have trouble removing the starter bolts.

You could just replace the seal instead of the trans, if you haven't damaged the trans with low fluid.

I think the transmission is kaput since itís making noises with it being full.
Didnít know there was a seal that could be replaced. Wished BMW had a method to check the fluid level on this car.
