Circuit Description

WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

While driving in 2nd gear, line pressure is supplied to the 2nd clutch piston, the 2nd clutch engages and the shaft and 2nd gear rotate together to transmit drive force. Oil pressure is supplied to the 2nd clutch via the suction filter, oil pump, main regulator, manual valve, shift valve, feed pipe and clutch piston. The powertrain control module (PCM) calculates the mainshaft speed to output shaft speed ratio.

When the calculated ratio is incorrect for 2nd gear, while the PCM is commanding 2nd gear, DTC P0732 sets. DTC P0732 is a type C DTC.
