Stalling in LO gear
I have a 96 Grand Cherokee and am wondering is it normal for the engine to
stall when going downhill faster than the enginecan brake? When I switch to
4WD and put the auto trans into 1st gear and start climbing a steep hill, if
I let the jeep roll back a few feet on an incline, the engine stalls out and
the engine light comes on. Same for going downhill. I have it in lo gear
and begin my decent, if I let go of the brake and try to let the engine do
the braking, it stalls when it picks up a little speed (5mph). I though you
are suppose to use the engine braking feature in lo gear to help you with
decents. Am I doing something wrong or is this normal?

Re: Stalling in LO gear
Something is wrong with your rig....
I would take a wild guess at maybe a vacuum line off or loose or
cracked?
I have also heard of improperly installed CB's messing with the
transmission computer?
You have a throttle position sensor that had some feedback to the
transmission or maybe the other way around. Maybe it's dirty? The plug
on our TPS got dirty and my rpm either raced high or it up and stalled.

If you're trying to roll backwards with the jeep in a forward gear(at
least, that's how I read this)that might be the cause of the problem.
To engine brake in reverse, you have to be in the reverse gear.
The engine light will come on if the engine stalls, not necessarily a
fault there.
