i have a engine and ecu out of a 94 gmc sonoma.
the transmission is a 700r4 and i was told it was out of a 90 s10.

i have been looking around trying to figure out how to hook up the speed sensor and it seems i need a speed sensor buffer to accomplish this..
the original transmission for this ecu is a 4L60e so the programming will need to be changed.

whats worse is that the speed sensor buffer seems to be custom programmed to the axle gear ratio, and is no longer offered.

any ideas?

can i get an aftermarket sensor to fit in the transmission that i can directly wire into the ecu?

the truck runs now, but i was looking into making it better and it was mentioned that connecting a speed sensor would be a good thing to do.

any help would be appreciated.

thanks, grum
