Oh OH I just cleared it and took it out for a ride. Shifting happened in the right places and when it got to 3rd and I backed off of the throttle the tach dropped slightly and tracked evenly with the spedo. Then if I hit the gas hard it would rise faster than the spedo. Then the Check engine light came on and the tach no longer stayed in synch with the spedo. It wouldn’t take a lot of gas to make it rise up a couple of hundred RPM.
Am I looking at a junkyard trans or can I ignore it? Is there anything I can try? Are the actuators inside the trans or outside and can they be changed?
