Thread: Possible TCC RPM Problem

On the Highway in very light throttle and right around 2000 RPM the Tach will jump a few hundred RPM. Just a touch more gas 2200 RPM no problems. Trans rebuilt about a year ago.

Also my TSC Light and ABS Light is on I think that is the Right Front Sensor. If that could have anything to do with it

Just checked my Codes on my scan Gauge
P0620 Not sure what that is
P1133 I get this sometime I think because of my O2 Simulator
P1571 Traction control because I have the Light I guess

First thing I would suggest is a good throttle body cleaning and plugs/wires if they are older. Very often this type of issue is tune up related.

A quick google search
P0620 Description Generator Performance
1133 is your front O2, so it wouldn't have to do with the simulator for the rear O2
1571 http://www.gearchatter.com/viewtopic8503.php Likely a bad EBCM

Seems like you have a few things to fix up.
