Subject:
TRANSMISSION REMAINS IN "LIMP-IN" MODE AFTER ENGINE START, NO DTC IN MEMORY
This TSB supercedes TSB-08-23-005REV, issued June, 2008, to add 2008 & 2009 Raiders. Revised information is shown with <.
PURPOSE
Some customers may complain that their vehicle's transmission intermittently remains in "Limp-In" mode (second gear) after an engine start. The transmission will not shift to a higher gear. If the engine is turned off and restarted, the transmission will often perform normally (not in "Limp-In" mode). There will be no transmission related Diagnostic Trouble Codes (DTCs) present.
"Limp-In" mode is used to protect the transmission. The transmission logic will remain in, or revert to, this mode if certain required operating parameters are not met in a specified time during engine start.
To eliminate this condition, reprogram the PCM according to the instructions in this bulletin.
