If I was to change the gears in my car I just have to adjust the speedo right?

I don't have to re-program the PCM right?

I have a 700R4.

 

You have to get a speedo recalibration box and splice it into the wiring harness. It's like $80 from SLP, but I caught wind of a rumor that they quit selling it. The speedo can't be reprogrammed by doing a computer chip.

 

Can't you get a gear clip for the speedo cable from GM that would make it 3.73s?

 

Just change your speedo geers....it'll save you a lot of money compared to the SLP recalibrator

 

Just pull the tail housing off and the driven gear/sensor the plastic gear on the mainshaft is stubborn comming off. swap both gears and this will be hunky dory.

 

thats what i did and it worked great

got mine for less than 30 bucks from slp when i got my torsen

oh and it is a PIA to get the main shaft gear off have fun cause its way cheeper

 

Awesome thanx guys!
