I finally found what I needed to repair my transmission after wrecking my over drive on the way to the home coming .
while waiting for parts i replaced the original t 5 with another from a s 10 with a 3.76 1 st gear and a .86 o/d.
I could live with the .86 o/d but the 3.76 1 st was way to low ,almost a bull gear and the 2.18 2 nd. gear left the smell of asbestos in the air when using it as a first gear.
Well I found a Camaro v/8 unit with the needed .72 o/d , replaced the top and tailhousing with s 10 parts . This seems to work well with the 3.90 rear end but the real test will happen this week end as I plan to travel to the Syracruse ny. nationals this weekend.
Originally the same transmission was mated to a 4.57 rear end , but I thought it reved to high at highway speeds.
I'll let you know how things work out when I get home sunday night.

good planning is no substitute for dumb luck
