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 3rd gear, line pressure is supplied to the 3rd clutch piston, the 3rd clutch engages and the shaft and 3rd gear rotate together to transmit drive force. Oil pressure is supplied to the 3rd 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 3rd gear, while the PCM is commanding 3rd gear, DTC P0733 sets. DTC P0733 is a type C DTC.
