Can I transplant a '82 manual 4-speed + OD transmission into my '94 940 turbo? 900

Well, actually it is a '87 760 sedan body with a full turbo engine/auto transmission transplant from a low-mileage '94 940 wagon. The transplant included the dash board, all instruments, all engine controls, the rear differential/wheels, and the entire wagon's suspension. Oh, and the larger front disks. It was a lot of work, and I could not have done it without the Volvo electrical schematics.

I have a donor '82 240 with a good manual transmission and overdrive. I also have a repaired but marginal mid-80's (don't know the exact year) 740 wagon manual transmission with overdrive, hydraulic clutch, clutch/brake pedal assembly including booster and brake/clutch master cylindars, drive shaft with center bearing, transmission support crossmember, bell housing, shifter cage, rather trashed shifter (no knob, and somebody took a grinder to the top of the shaft), flywheel(don't know the tooth number), several lightly used clutches, replacement cable clutch fork with pivot, and all the bolts from the donor car. I don't know whether it is a J- or P- type overdrive from 740.

I believe the only important parts I lack are a 7xx/9xx overdrive solenoid and a new clutch bearing.

So, my *hope* was to use the '82 240's manual transmission + OD, wrap it with the 740 bits, and put it into the 760. Then I'd have a manual turbo 760 -- which will be much more fun than my automatic transmission.

If the 740 manual transmission has a P-type OD, can I swap that onto the 240 manual transmission?

I intend to rebuild the OD using an after-market kit - any advice on this is appreciated. I also intend to replace front/rear transmission seals, rear engine oil seal. Depending on wear/appearance, I will replace the drive shaft center bearing, U-joints, clutch hydraulic line, transmission/engine mounts.

Any advice you have on the foregoing is greatly appreciated.

...My wife thinks I'm crazy and I haven't told her EXACTLY what this will cost. Or how long it might take. But I really hate driving an automatic.

Thanks for the help!
