you have a Warn
Overdrive correct? ok I am not so sure how it works with an auto as when it was developed Jeep only put sticks in the jeep
but it is a 25%
Overdrive
in a stick you put in the clutch and push the
Overdrive stick all the way forward to go into
Overdrive .
now remember. this is a planetary
Overdrive set of gears. so you can use it no mater what gear you are in.
Let me explain
the unit is in the PTO pot of the T case. what it does is when the shift is in the
Overdrive position, it uses the planetary gears to up the ratio of the gearing inside the t case.
As you can see if you are in 1st you can start out 25% higher.
I usually run my 70
CJ6 that has the OD unit in it in OD unless I need the extra power of the lower gearing of having the OD stick pulled back to the driver.
Now, I have read that if you have an auto that you can shift on the fly however knowing the cost of new gears for the OD unit I would do the shifting before I was moving as it could cost a bit to experiment.
That unit basically turns a 3 speed into a 6 speed as every gear gets a 25% boost upward.
