Re: Making an s-10 transmission work?
That is a T5 post 1987 S10 (or GMC S15 - same thing). If you have the TAG # that would help identify the gearing. The number would be 1352-XXXX. The numbers that are cast into the case or tailshaft are NOT the same as the actual TAG#. With an electric speedo drive, it would probably be 1987 or newer. I cannot tell if it is WC or not. I'd need to see the input shaft side of the case to tell what the countershaft bearing looks like. See my website and look at the T5 page along the top banner and you will see a whole bunch of info about the T5.
Before you buy:
1. Realize that you will likely need an adapter plate which costs around $160.
2. You should make sure it shifts smoothly and turns freely in all gears.
3. You should figure out what the 1st and 5th gears are - see my website for instructions. The 0.76 and 0.78 and 0.72 5th gears are very nice to have. Many S10 T5s have a 0.86 5th gear and those are less desirable but still worth having if you want a little better highway MPG. The 0.86 5th gear is not bad coupled with a 3.42 rear.
4. The replacement parts (namely gears) for a non-WC T5 are not easy to find since they are no longer made. WC T5 parts are readily available. That's why a WC would be a better purchase.
5. The T5 from many 93 and up GM cars and trucks has a FORD pattern case and will not match up to your factory Chevy bell. Beware before you buy! Make sure it has the "ears" on the case where it bolts to the bell housing.
Send me a PM with your phone number and I'd be happy to help more if I can.
