Review on Dorman 924-715 Ignition Switch optimized for Select Models by Roger Weinmunson

. After reading the reviews on this product it seemed like the solution to gear slip problems with my 2003 Yukon XL 1500 5.3L. I installed this switch in April 2017 and in December 2017 my check engine light came on, the truck did not shift between gears, it just stayed in the gear selected by the gear selector.

My car gave the following codes which are basically the codes for each solenoid in the automatic transmission. ordinary.
