1G Will a 92 AWD tranny FIT a 91 AWD Tranny?

[93_GEE_ES_EX]

I have a chance to buy a built Shep tranny to replace my stock tranny.
The shep tranny is a 92 and my car is a 91, will it work?

Yes it will work but you'll want to make sure that the splines match up. You could have a 22 spline transfer case and the trans is meant for a 23 spline transfer case.

So I would also need the 92 transfer case?

What about vice-versa?

Find out what the production date of your 91 is, because 1/2 way through 91 they switched to 23 splines...or get a 92-94 x-case, and you should be pretty well set...maybe a few other mods, but not 100% sure.

Can I put a manual transmission from a [1990-1994 DSM] into a [different 1990-1994 DSM]?

What years of manual transmissions are compatible with my [1G DSM]?
DSM transmissions come in two types with different output shafts. 1990 and some 1991 cars have 22-spline output shafts. Later 1991 through 1994 cars have 23-spline output shafts. Please note that 1991 cars that are 'later' (i.e. have later production or serial numbers) may still have the 22-spline shaft. The best way to check is to look, or to check part numbers with a dealership.

The number of splines on the transmission output shaft must match the number of splines on the transfer case input shaft, or else the transmission will not fit. Some people have found it possible to swap shafts between the transmissions in question to match the parts up correctly. Alternatively, the transfer case can also be changed to match up with the transmission, with an associated greater cost.

There have been several syncro changes over the years to try and combat problems with 1G cars not shifting well. It is generally accepted that later transmissions have superior syncro designs, so if all other things are equal a later version may be superior to an earlier version. Also, 2G transmissions can be put onto 1Gs with some simple modifications, and can provide superior performance. However, most people do not have free choice of transmissions due to economic reasons.

It must also be noted that the manual transmissions from turbo FWD and non-turbo FWD cars are different. Non-turbo FWD 1Gs have a F5M22 transmission (manual) or F4A22 transmission (automatic). Non-turbo 2Gs have a F5MC1 transmission (manual) or F4AC1 transmission (automatic). Turbo FWD 1Gs and 2Gs have a F5M33 transmission (manual) or F4A33 transmission (automatic). These transmissions are not interchangeable, and they are geared differently.

Hope that helps you or anyone else bro. Also this has been discussed, countless times, my self personally have answered it about 10 times.

Wow thanks!

Hope I could help you bro.

I'm pretty sure I have a "late model", 91AWD GSX turbo and was wondering what 2G tranny will fit?

The last post as i interpeted it was about FWD not AWD. Could someone help? I'm having problems shifting into reverse. Sometimes it goes most of the time it doesn't. When it goes in reverse sometimes it acts like its stuck "park" and stalls out...

Thanks

1G GSX

BTW its a manual

Just to add, it is very simple to swap output shafts on the trans. If you have a 22 and are getting a 23, just swap the 23 spline for your 22.

What about the cables?Can I use my 91 shifter cables with the 92 awd tranny?

Yes, same equipment
