Not sure what transmission to use

[jocko]

I kinda have to agree with the above comments about strength. If you're just tooling around and never plan a burnout, it should be ok, but it's not ideal. If you'd like to preserve some truck capability, I'd go with Leon's 4500 route. If you still want to use the T5 just because you have it, here's a great post by a "highly skilled" mechanic... Ha.

As Leon said, you can just go with a new disk for an Astro - however, if you need to replace the disk and pressure plate - recommend going with a KIT that includes an Astro disk, pressure plate, AND release bearing. All three should be purchased together if you're doing anything beyond only a friction disk replacement to ensure you have the correct total depth of the comb - some release bearings are thinner/fatter and some pressure plates are fatter/thinner - so you want to make sure you're getting a proper height combo - if you buy as a kit, you will get the correct combo. Anyway, maybe a few useful lessons learned in the link. Good luck.

EDIT: and you can ignore the homemade spacer drawings on the back of a napkin in my thread, just buy one from Hamilton Intakes. They didn't have any when I needed one and I didn't want to wait. I think they may have more quantity available now, demand has been growing.

EDIT # 2 keep in mind that a 94 S10 trans has an electronic speedo connection, not the cable (I THINK). But something to consider. Some folks will wave off completely for this reason - but I know there are ways to make it work, some expensive, some maybe not. Black magic to me! I like mechanical linkages
