Pushing the OD-off button will leave you with 1st, 2nd, and 3rd gears.
OD-on adds 4th and 5th.
I’m pretty sure that’s not true on mine. My Jeep turns about 1100rpm going downhill do off
When you push the button, the OD-off light should be lit on the instrument cluster.
If the light doesn't come on then the button isn't working.
If you are not feeling the downshift maybe its because the transmission is already in 3rd.
Engine braking from downshifting is relative to gear selection and vehicle speed.
If you are at or below 25mph and pull the shifter down into 2nd, you'll feel it. Although sometimes there is a delay. (I do this frequently)
The factory transmission shift pattern is like this:
OD-on:
2nd @ 10mph -> 3rd @ 20 -> 4th @ ~40 -> 4th +TC lockup @ 51 -> 5th +TC lockup @ 61
OD-off:
2nd @ 10mph -> 3rd @ 20 -> 3rd +TC lockup @ ~40
Note: you usually cant feel the upshift into 2nd and TC lockup feels like a shift into a higher gear.
