I have the gear transmission installed which has 3 separate gears.does anybody know please?thank you
The D4 RWD is belt driven with a 2.06 internal ratio

The optional gear transmissions for the D4 are 1.9 internal ratio ... SAK-D4841

To calculate the internal ratio on a 3 gear transmission divide the diff gear by the top gear, the middle gear is not used to measure the ir ratio.
