Swapping Turbo Engine into Manual Transmission 850 (non turbo) 850 1995

I've got a 95 850 turbo wagon with automatic transmission - 160k and in really good shape

I've also got a 94 850 non-turbo wagon with manual transmission - 200k and plenty of issues, but transmission feels great.

I really miss the manual transmission, and darn it like the turbo too. I've read elsewhere the step by step summaries people have done on swapping transmissions. It occurred to me that it might be easier to swap the engines . . . anyone have any insights here? What is a typical life span for a 94 manual transmission?

    I would just swap the transmissions. The manual is due for a new clutch and RMS anyway. Manual trannies last forever, if you change the fluid occasionally. Swapping the engines is much more painful because of the electronics and getting the engine up in the air.

    The 1994 should have a TCU that can be put into the 1995 which will help the performance, but is not really needed.

    It is going to be a lot of work, but then your 1995 will be able to smoke the tires!!!

      TCU -> Transmission Control Unit? I'm confused why the manual transmission would have this - just to run the idiot upshift light or is it something else altogether?

        The TCU and the ECU talk to each other. The auto and manual have different gear and final drive ratios. I am not sure if the speed sensor is in a different location, probably not.

        Using the auto TCU will work, but it is not optimized. Remember, there is no PNP for the manual, but there is a clutch switch to disable start.
