Swapping in an s60 M56 / Manual transmission compatibility

Post by Kara503 » Tue May 29, 2018 12:51 am

All-

Looking to swap my 96 855 auto to a manual. I think I have the knowhow and have seen the swap threads. My question is on parts sourcing.

Is a late model M56 5 speed from an early s60 or v70 (01-03ish) a straight swap into an 850? If not, what doesn't work? Do all of the mounts and holes line up? I have been having a rough time finding a 5 speed 850 worthy of dismantling.
What about all of the other bits? Shift cables, pedal assy, shifter knob, reverse switch, etc?

My gut says the transmission itself will mount and function just fine, but I'd need to source and 850- style slave cylinder (I think the s60s have an internal slave?) along with the pedals.

Thanks :)

Best to just keep your eyes open for a parts 850 for easy swapping.

Pedal must be 850, not even S70/V70's work.

98+ M56H have internal salve cylinder, so you'll have to account for that and get the right lines. You have to use the transmission matching the correct slave cylinder, they can't be mix / match! You'll also want to ditch the dual mass flywheel and find a single mass flywheel and use R clutch. At the end you might as well find a non running 5 speed 850 to get all you need from it.

People have put space shifter into a 850, but that's all customization. Don't expect anyone but yourself for help.

That's really too bad, there are 2 M/T non running P2 cars near me for cheap and no 850s. The wait continues!

On that shifter..... oh wow. Ew.

Oh wow, good eye! Didn't think too look in Idaho. Not quite ready for an 8 hour drive from the Portland Metro area though. Will keep my eyes out for a regular 850. Thanks tryingbe!

If you can't find an 850 5 speed shifter I have one pulled from a 93 850. Pretty sure I'll have no use for it. PM me if you're interested. I also have the tranny bought the kit and stored in garage since 2008. The car was immaculate except for right front fender ding.
