A Technician’s Tip: Many drivability problems on these GM platforms are incorrectly blamed on sensors or the transmission. A faulty PCM can send incorrect signals, causing other perfectly good parts to behave erratically. Before you spend hundreds chasing down other components, consider the ‘brain’ of the operation. A correctly programmed 2006 Isuzu Ascender PCM often resolves a host of seemingly unrelated issues, getting the entire system communicating correctly again.
