MVS Contributor tryingbe goes ALL OUT doing an auto to manual transmission swap. He has outstanding information and warnings on what to buy, where to get it, and the transmission swap to do list. This Volvo forum topic joins the many others here on manual swaps.

The topic was started by beigg who asked…

  1. What is all needed for electronics/electrical?
    PCM, TCM, engine harness from the auto able to be left alone? Main concern is functionality. If the auto harness only requires a slight PNP connector modification [ ie. ground to bypass starter and addressing reverse lights (not a real concern for reverse lights). ] and everything else can be used while being plug and play, it make this area pretty simple. I couldn’t imagine the speed sensors would differ in connections if I stayed with a 96-98 manual for use.
  2. Drive-line components similarities?
    Are the axles same spline and lengths for both ps and ds? Brackets for the mounts same? It’s a long shot, but are the mounts going to the brackets same?
  3. Power-train expectations and common changes?
    Flex plate and t-converter will obviously need to be tossed out for a needed flywheel, cd, pp, tob, and master/slave combo. Thinking for anything that might be a show stopper, I’m not foreseeing anything at this time, but I could be wrong… I’ve been wrong in the past. Any of my friends (especially those female) can attest to that!
  4. Cooling system doesnt set off any red flags that would mandate needed changes.
    Radiator would just omit the auxiliary cooler, which is a plus for any reason an aftermarket auto radiator is installed; breaching systems are awfully too common.
  5. What to avoid, to consider, and maybe to take special note of?
    Would not want any surprises, but I’d be foolish to assume that. Limiting those surprises, however, would be greatly appreciated!
