1996 Camry V6 XLE 233K miles. Occasionally but only during heavy rain the engine surges and trasnmission seem to hunt for a gear. Anybody have ideas?
Doesn't alway exhibit these symptoms even in rain. The noise is very promounced similar to what I used to have happen years ago with my 78 Cutlass when it locked up the fan-clutch. Transmission & differential are fine. Engine torn down at 70 miles for the poor oil circulation problem which didn't help much with the noise so the lifters have made other than quiet for decades, Mileage is fine ~25 mixed. Mobil One 5W-30 every 3500 miles.
im going to guess its your throttle position sensor. bad TPS units can cause hunting and erratic shifting.
i think water is leaking in the cylinder from the air cleaner box
