Hmm. Had a couple downshifts on the highway (3-2) at no-throttle and a few hiccups when cruising lightly. Codes point to the Throttle Position Sensor but the test shows it to be nice an smooth with no drop-outs. Passes the volt-meter test.
Transmission fluid is fine, no bubbles, correct level. Kickdown cable is adjusted properly. No bits of tree wedged in the link. :)
Guess I can throw $40 worth of parts at it.
5234904 (Advanced Auto has the BWD EC3310 for 38.19 and the Delphi SS10482 for 48.09) Amazon has the Delphi for 34.56. Think I can find replacements just about anywhere. Quite a bit of $ for a simple vairiable resistor. Should be closer to $18 if you ask me.Wondered if anyone else had similar issues.
The only other thing I have is potentially a weak battery. But since the TPS sensor is 5V that shouldn't be an issue. Gonna have the battery tested anyway.
