Getting my MPH to be right?..HELP
Alright so here's the deal. I'm going from a lock-up700R4 with 2.73's to a built no-lock up 700R4 with 4.10"s posi. To get my MPH right I know there's a gear that needs to be changed in the tranny but can someone lead me to the right one and would that be the only thing that needs to be changed? Thanks for all the help guys!

Re: Getting my MPH to be right?..HELP
700R4.com sells the gears - you'll need two more than likely, the driven and the drive gears. One installs in the tailshaft of the tranny on the output shaft, the other installs on the driver side rear in the speedo housing.
