could you actually tell me what rpm to shift at lol that would be nice thanks
Shift it as though it were an automatic, maybe 2200 second, 2400 third,
thanks lol
Does a little yellow arrow on your gauge cluster in the top right come on? My TJ has one and it's a "shift indicator" although I've been driving 5spd for years and find it annoying, it's helpful for new drivers.
p.s. is there any easy way to make that light stop turning on? I find it distracting at night.
You could take out the bulb. On a YJ it is pretty easy to get at, I don't know how hard it would be on a TJ.
No, no, that isn't a shift indicator, that is a this side up arrow isn't it? ;-)

I have always shifted at 2000 RPM. But when I am towing a trailer I shift at 2500 RPM. Hope this is of any help.
lol!

How does it determine when to turn that light on? I've seen it turn on as low as 1300 RPM, when shifting would lug the engine badly. AFAICT it is the "if I were an automatic transmission you would be fighting with me now" light.

Ours turns on at 30 mph in 4th gear so it 'must' just be pointing the way. :-)
I believe it relies on vacuum pressure from the way it acts but could be mistaken, if rpm were in there it wouldn't come on at 'fast idle' rpm speeds I wouldn't think.
Ours had a vacuum front axle disconnect too and we had to futz with the gas pedal sometimes to get it to turn off the 4x4 light and unlock.

How about putting a small piece of electrical tape over the light. I use to see this all the time with the Check Engine lights in the older cars.
