Transmission Fix
Hi and thanks to the previous posters. My transmission was slow to engage - forward/reverse both hot and cold. The delay way up to several seconds (knida awkward when you are parallel parking with traffic waiting). I printed this information that I got from this forum, and handed it to the dealer service manager.
From a previous post on this forum
CAUSE:
541011 SHORT TEST, PERFORM 7855 W67
540991 CONTROL UNIT - SOFTWARE (AFTER SHORT TEST) INSTALL 7855 w67
CAUSE:
CONNECTED DAS. FOUND NEWER SOFTWARE IN ENGINE BUT NOT IN THE TRANSMISSION. CORRECTION: PERFORMED ENDING SOFTWARE FLASH/PROGRAMMING/SCN CODING. PERFORMED SHORT. TEST.
My service order: ($141.50) 12/2019
VERIFIED CLIENTS CONCERN. HARD = DELAYED ENGAGEMENT WHEN SHIFTING INTO REVERSE. PERFORMED SOFTWARE UPDATE + SCN CODING OF TRANSMISSION. RESET REVERSE GEAR ADAPTATION. RE TAUGHT IN ENGAGEMENT SEQUENCES FROM N-D + N-R. HARD ENGAGEMENT ELIMINATED. VEHICLE NOW OPERATING NORMALLY.
Car fixed - Thanks to the folks who posted and helped me get this corrected!!!!
Hope this helps others....
