Transmission button on dash


Recommended Posts

What does it mean when my Trans button on the dash lights up?

 

I know there is a little light that is supposed to come on if I flip the switch up. That doesn't work. BUT sometimes when I'm driving the trans picture lights up. It goes off if I hit the button and won't come back on.

 

Just wondering what that means.

 

Thanks,

Ron

There is no tranny lockup switch. The switch sets the tranny in "Power" or "Comfort" mode. Basically, comfort mode makes the transmission upshift at lower RPMs. Later year XJs and MJs eliminated it and hard-wired the tranny in the "Power" mode. Put it there and leave it, the tranny will thank you.

Hey Eagle, did not realize the POWER/COMFORT switch was hardwired to the POWER config later. My 91 might as well be, has not left the POWER mode for at least 7 years. Better mileage, crisper shifting, better performance.

we leave the xj in comfort mode, shifts smooth as butter, and i've heard comfort saves gas cause it doesn't rev as high :dunno: either way it a xj on 35s... gas mileage has long since been null and void. :roll:

 

but the switch is nice, tap power mode and she kicks it in for up-the-hill action or passing and such

IIRC, comfort mode makes the transmission "slip" to generate a smoother feeling shift.

 

I know the previous owner kept it in comfort mode, and I keep it in power mode. My tranny seems to be sloppy in comfort mode, especially at higher speeds. Besides, i'm a bit of a lead foot ;)
