EASIEST WAY TO FIND OUT JACK UP 1 REAR WHEEL ,COUNT ROTATIONS OF DRIVESHAFT TO 2 REVOLUTIONS OF THE WHEEL. THAT WILL BE THE RATIO.GOOD CHANCE IT IS A 4.11 TO 1 THOUGH HAVE SEEN 4.56 TO 1 IN SOME.TO CORRECT YOUR PROBLEM YOU NEED TO CHANGE GEAES ON TRANS OUTPUT SHAFT AND CABLE GEAR.DEALERS CAN MAKE A REDUCTION GEAR THAT GOES BETWEEN TRANS AND CABLE.
