Re: Quick trans question
When driving on the highway with a constant speed, the torque converter clutch (TCC) will be engaged and the torque converter is bypassed, making the connection engine to transmission a fixed one, reducing losses and heat buildup from a slipping converter. Normally, when accelerating just a bit, the TCC wil stay engaged and the rpm just increase gradually with the speed. When accelerating faster, the TCC will dis-engage, and the engine rpm will go up quickly. If this happens even with a very little extra throttle, it is not normal.
