9 times out of 10 it's the pressure control solenoid in the transmission causing the problem, over time these solenoids get clogged and cannot perform their function properly, shifts take longer and the computer reads this as low pressure, then send a signal to the pressure module to apply full pressure to prevent the clutches from burning out. It's a real PITA to change out, part is under $100.00 and trans shops want around 6 to $700.00 (sometimes more) to do job because almost all the front left hand side suspension and steering must be either dropped or removed along with the motor mounts to access the trans axle cover plate. Computer will store error code P1811 if this is your problem, had several like this and only fix was to replace the solenoid, funny thing is one of them didn't have the code recorded in the PCM go figure.
