Yes on the 60-E and 65-E the PCM depends on the TPS for engine load( Upshift / Kickdown signal ) If the TPS is virtually dead the trans will shift super early and at time you may have no kickdown with your foot on the floor

Connections and wires are good on both sensors. I am going to try both sensors and see if that takes care of it.

krandall...try using a multimeter to test the TPS per the Techinfo article. That will tell you if the TPS is good w/o buying one.

For a TPS, an anolog (watch the needle move) meter works best. If you're digital, go SLOW. Dead spots are very hard to spot.

I agree. I've found it virtually impossible to follow a digital meter while checking the TPS. You have to be very careful to catch any fluctuations in the reading.
