Solenoid circuit error: LR

CODE DESCRIPTION
A shift must not be in progress; a selector lever position, pressure switch, or watchdog test must not be in progress; no spike must be detected from the solenoid during the first test, or a pressure switch problem, or a speed problem. The code sets if the solenoid continuity test failed for the second time, or if there is either a pressure switch or speed data problem and the solenoid continuity test failed for the first time.

- Malfunction of pressure switch assembly
- Hamess or connector between LR solenoid and TCM open or short-circuited
