standard transmission swap

would a 98 V70 manual transmission bolt up in a 94 850 turbo? i know i would need an ecu as well, just wondering if it would physicly bolt up?

The ECU (ECM) is going to be a problem. There were no US specified turbos with a manual transmission hence there are no junk yard ECUs that won't freak out and set a CEL. The ECU from the V70 won't work either.

Some of the tuners may have cracked the code but I don't know specifically which ones. The car will run just fine but when the ECU can't talk to the TCU it will set a CEL.

Wouldnt a TCU from a N/A manual work? Just because im curious, would the car drive (with the manual) without a TCU alltogother

The manuals don't have a TCU beyond the guy or gal that is behind the wheel with a foot on the clutch pedal and a hand on the shifter. There is no module in the slot.

Some manual TCUs are better than others, it drives me nuts when my wife goes for second in the middle of an intersection from a stop light but I do have the low geared M-56 in the '94. By the time she has dumped the clutch she goes for second, I wrap it up to around 4 grand before I make the move.

The rub is that the US versions of the ECU expect to have a dialogue with the TCU and when the communications stop (as in the automatic transmission and/or the TCU are gone) it freaks out and throws a CEL.

I do believe there are ECU tuners that have dealt with it but I don't know which ones, the last I heard was that IPD had not but perhaps that Rica had, that would make sense since Rica is based in Europe.

I have never used them or their parts and I don't endorse them but I have hear that they are quite good. They may also be quite expensive with the ever shrinking dollar.

ok, thanks, i understand now. Do volvo manuals have any tendanceys to wear or break internal parts? The one im looking at is from Toms foriegn auto parts, out of a 98 S70 with 152k miles

Mine is all original with around 227k miles on it, even the clutch is original as far as I can tell. No problems with it whatsoever.

Same here. 198k miles on our M56 and it shifts as smooth as ever.

good good. i found a site that sells limited slip diffs for the manuals, does that mean the stock diffs are open? is M56 what was used in a 98 S70?
