The Ford Barn - View Single Post - t-5 confused which one?

The older S10 T5s from 82-83 (?) until sometime in '88 mostly had the very low first gear (stump puller - normally behind a 4-cyl)) and the mechanical speedo tailshaft. The 88-92 usually had the more desirable first and 5th gear ratios but an electronic speedo tailshaft. So, most will combine the better gearset from the later 88-92 trans to the older mechanical tailshaft.

A couple gauge manufacturers do have speedos that will synch with the pulse (?) output of the S10 electronic speedo - I personally have been just skipping the tailshaft swap in favor of a GPS box hanging off my windshield. There is also a GPS speedo converter (?) you can buy now but it's a bit pricey at the moment.

Casing numbers should start with 1352-xxx but the tag off of one of the lower bolts holding the tailshaft to the head of the tranny is the one that gives a number you can look up and get the gear ratio off of. Flat Ernie has gobs of info on T5s - just do a search here on this forum for T5s or Flat Ernie and check the link he has when he posts. He may also comment here at some point ....
