Volvo Auto Transmission to Manual Conversion

What You Need For a Conversion to Manual

  1. You need the pedal assembly with clutch pedal form a manual 850
  2. You need a manual transmission M56 H or L “any 93 to 98 850 turbo or n/a”
  3. You also need the two control cables, and the shifter assembly that replaces your auto shifter
  4. You need the master cylinder, slave cylinder, and pressure line
  5. You do need to either plug you PNP switch back in so it will allow the car to start. Or put a jumper wire in the connector.
  6. You also need to wire the manual tranny reverse switch to your harness so you have reverse lights
  7. Lastly you will need a clutch assembly, “clutch plate, pressure plate, throw out bearing”

Manual Swap Notes from a DIY Owner

I decided to remove the entire drivetrain, swap the transmission and reinstall the engine/manual tranny as one piece. I don’t have air tools but I did have a friend help me for at least half of the job. I did it over a period of three days and probably a total of 12 hours. Interestingly enough I spent at least 5 hours of that time installing the clutch pedal, master cylinder and bleeding the clutch.

I have at this point pulled 3 850 engines.

“all due to transmission’s” and two of these instances were in 2010! Hence I bite the bullet and got the manual gear, as I seem to be to attached to the car to let it go.

But I am not a mechanic, just an average guy who tries to do his own stuff. “tries”.

I understand that volvo charges 8 to 9 hours to change the clutch in a manual 850. But there is alot more to it when you have to change everything inside the car too. pedals, shifter,cables, etc……

I actually found it to be an easy swap, short of the clutch pedal assembly. Had to dissconect steering column for this and very awkward position to work in.

I did have one huge issue, car won’t run.

But it is a damaged crank sensor not allowing spark/fuel. This is most likely my fault, or coincidence that the sensor finally died at this time. I have read many swaps and the guys didn’t have the no start issue, so don’t let that scare you. I’m just special..

More on the Volvo 850

Volvo unveiled an entirely new model series in June 1991, the Volvo 850 GLT. The Volvo 850 GLT was launched under the banner of “A dynamic car with four world-beating breakthroughs”.

The four new features were: transverse 5-cylinder engine driving the front wheels, Delta-link rear axle which combined the dynamics and ride comfort of independent suspension with the security of a live rear axle, the SIPS integrated side-impact protection system, and the self-adjusting front seat belt mechanism.

The exterior design of the 850 bore a strong Volvo identity, and its 740 and 940 heritage was immediately apparent.

Volvo 850 GLT received a tumultuous welcome; seldom has a new car reaped so many awards as the 850.

Over the intervening years, the 850 series has been expanded with additional variants, among them turbocharged petrol versions and a direct-injection turbo-diesel.

The Volvo 850 was also the first car in the world to offer side-impact airbags, which were introduced in autumn 1994.

In model year 1997, the S70 replaced the 850 Sedan car.

I have an S70 T5-R 1998 volvo,that had a transmission problem,,,i had already changed the transmission twice,and the problem came back,as the car is american spec,moded by IPD,TME,DAZZ,Koni and Razo.
I guess those upgrades had made the gear life less,,,as it cant overcome the power,so the car is now in Dubai,U.A.E and i cant find the perfect garage or person who can convert it to manual,,,and the volvo dealers dont want to deal with imported tweeked car as thier excuse is ,it is not street legal and their labours are only trained in stock car repairs,so i hope some one guide me where can i find the proper place to convert such a rare car from automatic to manual transmiision,thanks.
