In Reply to: stalling due to transmission by jmgarland77

Stalling is RARELY due to an automatic transmission. Anyone telling you otherwise is either trying to sell you a tranny or doesnt know what they are doing. The transmission does not lock up to the engine until it is doing over 35 MPH, prior to that speed the torque converter is strictly fluidicly linked to the engine. if it is locking up before that it is electronic control ot the torque converter malfunctioning. The torque converter is the automatic equivalent of the clutch, and NOT the transmision. These issues that you two gentlemen are reporting are most likely PCM (power train control module) issues as it controls the entire driveline function from the voltage regulator to the shift points of the transmission.
