1996 850 manual transmission bolts into 1995 850? Speed sensor?

Post by ollen001 »


I've searched this forum extensively but did not find the exact info I need.

I need a manual transmission for 1995 Volvo 850 GLT, or so the independent shop says.

I found an extremely low mileage 1996 850 manual transmission (30K, yes...) for $300 but it appears there is some "speed sensor" difference between the model year 93-95 series and the model year 96-97 series. Or so I am finding in the technical descriptions for the used transmissions.

Couple questions:

1) Isn't an M56 manual transmission the same for all 850 series?

2) Is it just the speed sensor or some other issue?

3) Can't I remove the speed sensor from the old transmission and install on the new?

4) Do I have to stay with 93-95 850 model year manual m56 transmissions? (Note: I'm not talking about installing M66 or any other model...this is just plain confusing.)

5) Also, will Volvo OEM R clutch fit into this transmission? I bought one with all Volvo OEM main seal, throwout bearing, pilot bearing, slave and master. (Yes, I am keeping this car.)

6) Why do I keep driving this car?

Volvo gods, please help me or I will start swearing in Swedish since I speak it...(Djaevel anama... fit och fan...osv, osv, osv)

Somebody, throw me a bone or a wrench.

You can use that transmission and that clutch- to get the speed you just have to tap into an abs sensor there are lots of m56 differences different strengths as well as internal or external slave- I put an 05 into a 94 and had no speedometer issues once I tapped into the drivers side ABS sensor- I still don't have cruise thought

1995 850 CAN'T have Motronic 4.4.
It's a bit rare even in '96 but ALL '97 have it.
1995 850 n/a B5254FS can only have Jetronic engine management.

About transmission compatibility....skloon already answered it.

Convert the 1995's speed WIRING to get its signal from the driver side ABS wiring at the wheel. Splice the ground wire to ground and signal wire to signal, use a multimeter to see which wire is which.
