This is some information that you may find useful about the Borg Warner T-5.

Note: Without additional adapters, the T5 and S10T-5 can not be used with a regular Chevy truck bell housing; they will only work with car/pickup bell housing as the measurements are different.

Random questions previously answered:

  • Hi, I have a T5 transmission out of v6 1996 Camaro 1352-247 and I need adapter to small block v8 can you help? Chevy used both Chevy bolt patterns with 14 spline and Ford bolt patterns with 26 spline on the V6 Camaros. If you have the Chevy bolt pattern with 14 spline long input shaft then the Hamilton S10-T5 is correct for your application, if not we can't help with that application(yet).
  • I want to install a T5 trans in my '81 chevy half ton. It now has a straight 6, three speed on the column. I have not purchased a trans yet and I hope you can tell me which trans would be best for this swap. Your adapter sounds like the way to go. How much is it? What about the driveshaft and cross member? Will I be able to use my manual clutch linkage or do I have to switch to a hydraulic? The bell housing bolt pattern to the transmission for your three speed is the same for all the Chevy T5s until 1993. There is two first gear ratio t5s, one is a 3.35 and the other is a 4.06. The 3.35 ratio is more desirable, because of it's strength. You can figure out which gear ratio the transmission is by looking up the tag number bolted to the tail shaft housing on the rear of the transmission. You can find the information to decode this tag on the Borg Warner website. You will need to remove your old transmission and bellhousing to figure out what size clutch you have. Then you will need to get the 14 spline GM clutch disc that matches your application. 10.5" the larger diameter s10 and v6 Camaro. 11" is the Astro Van. You will need to purchase a S10 T5 spacer from us, because of the 9/16" of an inch input shaft length difference. You will be able to use the original style throwout bearing and clutch system that your truck came with. I believe the s10 t5 is about 1.5" longer, so the drive shaft will need to be shortened and the cross member will need to be moved back.
