Hello All, New to the forum and appreciate what I've read. I got my first corvette, and ooooo is it cool. One problem I have though, the speedometer won't work until a mile or so down the road. I'm thinking the speed sensor on the transmission is going bad. The problem is, is GM no longer manufactures the part, and it's not available as an after market item. All companys catalog it, but when ordered it comes up unavailable. Does anyone here have any ideas as to weather this one can be rebuilt, or information on the whereabuots of a replacement. The Spec's are:
1990 coupe
ZF 6 speed
It has a RPO of "D9B"
This has a part # of 25007308
3.33 rear end (I think it's the same part as or for the 3.07)
Also was thinking that if part is so hard to get it might never go bad and I possible may have something else going wrong. Any thoughts?
Thanks Scott
FWIW, it you come up short finding that part, Dakota Digital has a Speedo correction box for $80 and a magnetic induction speedo sensor for an additional $30. I'm looking at that as a solution for my lack of speedo (and different rear-end ratio from stock)
