Hi, new member here.
I have a 91 900 stick with the 2.1 motor but the gearbox is shot. I also have two parts cars with good 5 speed trannys. One is a 86 900 turbo and the other is a 88 900 turbo. Will either one of those trannismissions mount up to a 2.1 engin? I have replaced a tranny in a 84 turbo a few years back so I can do the job.
Thanks for the help.
Gurn

We need more Tennesseans!


Yes, the transmissions should bolt up. However, the primary ratios may be different.

This write-up is for an auto-to-5-speed swap, but it should be a good reminder for you:

I've lost the link for the matrix showing the gear ratios and the primary ratios for C900 transmissions by year and model, but I'm sure that someone (Jezz?) has it...

Therefore, the '88 would be a very close match in ratios, and the '86 would give you a slightly taller final drive ratio -- slightly better for highway cruising, slightly slower acceleration (theoretically).

Personally, they're both a very close match -- I'd put in the one that's in the best shape.

Where in Tennessee are you?
