Need help figuring out how to connect a 1988 T5 transmission to a new 1955 2nd series gauge cluster. Does the cable need an adapter? Has anyone run across this before?
I cannot swear that all 1988 S10 T5 transmissions had a cable speedometer, but 1988 was the last year the cable speedometer was offered in an S10 T5. Starting in 1989, the S10 T5 used a VSS speedometer system.
Inside your T5 tail housing (if you have a cable speedometer connection) will be a plastic drive gear. Remove the driven gear housing bullet to see the drive gear on the main shaft. If the drive gear is blue, then it has seven gear teeth. If the drive gear is red, it will have nine gear teeth. Those are the only two possibilities.
The correct driven gear in combination with the drive gear, will make your cable speedometer accurate.
There are calculators online that can help you choose the correct drive gear and driven gear combinations to make your cable speedometer work.
