Are 5.13 gears to much?
For a 03 TJ with an automatic transmision and 35 inch KM2's
Front axle is a Dana 44----rear is an 8.8.
What kind of RPMS would I be running with OD on at 70 mph
I would not be honest saying "yes" with that same setup, but it would seem to me with such a ratio that those symptoms would occur unless different gearing in the trans would be set up for an od or something.
