i just had motive 3.73s installed and the master install kit w/ ta girdle.pulled away and had some issues.payed for a speedo calibration and shift points.cars an auto w/ tci superstreetfighter,shift kit.Already hearing little whinin and a big clunk when shift into 2nd.not normal?

Also i think my speedo is off.curious to know if they even did the calibration.i think its off by 5mph over what it reads.stock gears idont know if they had 2.73s, or 3.23s but how would ur speedometer react if it wasnt calibrated.is the whinin normal and why is it clunking into 2nd.i'll go back there monday but any technical info would help

If they didn't correct your speedo, your speedometer will show that you are going faster than you actually are(if correction wasn't done, and your speedo says 65, you are actually going slower than that).

We would have to know if you previously had 2:73s or 3:23s to know exactly how off your speedo is.

try this link out, itll tell u what your car is supposed to run with the tranny and gears, http://www.f-body.org/gears/

alos look in your glove box or drivers door for rpo codes
GU2, GV1,GW5, GS1 2:73
GU5 3:23

MOST Likely youll have either a gu2 or a gu5
