I recently did a t-5 conversion in my 91 Z28, and i'm trying to hook up the speed sender now. Ive still got the old automatic, but the sender from it is too big to fit the t5 tailstock hole. im still running the same rear end gear, but need to know what gear/sender combo to use on the t5 tranny. anyone ever seen the sender that painless wiring has???? i called and they said its 4 pulse, but thats all they could tell me, nuthing about the gears. anyone??????
