I would change out all the fluid and replace the filter, for both of you.
Make sure you use the correct fluid, not generic fluid.
Then see what happens. I didn't have a problem with my TJ.

TPS. Throttle position sensor. It signals for the clutch lock-up to
the engine control computer and can cause this condition.

Before starting the engine cycle the gas pedal several times, top to
bottom, vigorously, to exercise/clean the rheostat within the TPS.
This might shake something loose. If not, you can either do a voltage
check on it (many times this check out ok even though the TPS is still
the problem) or simply replace the TPS.

Also, you can hold in the trip meter re-set button, cycle the ignition
switch on/off, on/off, on/off, then on, watch the odometer readout or
count the check engine light flashes to count the codes to see if the
TPS shows a fault code.

If you do your own wrenching you can toss some parts at it and still
come out cheaper than if you pay someone to fix it.

RAH out.

Just wanted to say that I cleaned the electrical connections at the TPS and
the problem seems to be much better. I stop short of saying that its fixed
only due to lack of time behind the wheel. Anyway, thanks for taking the
time to reply.
