I swap my trans for a T-400. I have a 1995 Z28, how can I get my speedometer to work? Is there a kit or something to convert the T-400?

There's a VSS and reluctor from a mid 90's GM truck tranny that will work with the TH400.
If your car was an A4, you will be OK on the speedo calibration, but you will get codes/SES light for all the missing 4L60E electronic interfaces. If your car was an M6, you either need to convert the TH400 VSS signal (40 pulses per rev) to the equivalent of the T56 signal (17 pulses per rev), or you need to have your PCM flashed to an A4 program. You can convert the pulse rate using a speedo interface box from Dakota Digital.Fred
