I have a 2001 Oldsmobile Bravada AWD with a 4L60e automatic trans, I have replaced the pump and torque converter and changed the filter and fluid. Does anyone know why it takes 2 to 3 seconds to go into drive no matter if it is cold or harmed up? All other gears change fine automatically, But manually shit into 1st takes 2 to 3 to engage.
Could be. high resistance in the shift solenoids, low voltage to and or from the TCM, a bad TCM, low fluid delivery from the pump. You may have to take it to a tranny shop that can hook up electronically so they can do solenoid and TCM testing as well as pressure testing.
