Jeep TJ Auto Torque Converter

What gears do you have? What size tires do you have?

Is this happening on an incline or flat driving?

Oh yeah, when was the last time you serviced the tranny? and how many miles between servicing?

Is it possible you might have gotten water in it? even condensation?

It happens on flat road.

my f150 does the same thing, for about 15k miles now.

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.

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.
