Shifting Problem ???
Have a 1998 Jeep GC 4.0L that's having trouble making it's first
shift. The rpm's run up to over3000 while the speed hangs at 25mph.
Sometimes backing off the gas allows it to shift most of the time I
have to drop into netural then back to drive to get it to shift.
I've changed the transmission fluid & filter(fluid still red, not
black) tried resetting the computer and changed the throttle senser.
What else might help before going to the shop for the usual
LARGE bill???

Re: Shifting Problem ???
I've never seen transmission fluid that was black. I judge it by if
it smells burnt, which it usually does by the every two years, or twenty
five thousand miles change interval. If your leaving the safe zone at
one pint low, oil level, there won't be enough oil left in the pan cold
to work the servos to shift.

Re: Shifting Problem ???
There is at least om some jeeps a Throtle Position Sesor in the engine bay.
This also sends signals to the computer controlling the transmission
computer. If this malfunctions or is misaligned the gearshift could get
screwed up. Have been known to happen after enginge cleaning with to much
water used on this component.
