V70 Automatic to Manual Transmission Swap

Ever wondered if you could tackle an automatic to manual transmission swap on your Volvo? Find out for yourself because we’ve got the scoop from one of our MVS members who tackles the job on his V70.

MVS Member daryl robert recently provided a great description and clear photos of his 1998 V70 automatic to manual transmission swap.  Follow along to learn more about this great DIY project. In replacing the M56 gearbox, he removed the drive shafts along with the hub, opting not to use the manual drive shaft because of its poor condition.  His photos in the forum post also show the best jack placement and what the transmission looks like with the flywheel removed.  Daryl says, ”I used a 11/16 AF socket which didn’t damage the socket or bolts.  I don’t see why it is recommended to remove the starter motor.”

Anyone have pics of their M56 wiring (ie brackets locations, plastic conduit). Did they use any hard plastic wiring conduit similar to the auto gearbox?

The only wiring that goes to my M-56 is the reverse light switch and the vehicle speed sensor which is on the bottom of the transmission on the right hand side – just above the axle so I’m not real sure what you are asking about. It looks from the photo like you are showing the AT connector which really doesn’t do anything anymore.

 

On the manual transmission the wires from both switches / sensors just run in a small wire loom back to the main engine harness.
