1 vehicles · 1 makes · $800-$1,800 repair
Most Reported On
P0880 is an OBD-II diagnostic trouble code meaning “TCM Power Input Signal.” This code sets when the transmission control module (TCM) does not receive the correct power/voltage on its power input circuit. The TCM needs a stable supply to control shifting, so a power-feed problem can cause it to lose control of the transmission. Symptoms include erratic or failed shifting, the transmission dropping into failsafe/limp mode, and sometimes disabled related functions. The problem is typically in the TCM's power supply circuit (fuse, relay, or wiring) rather than the transmission internals. This code is most commonly reported on 2006-2019 Chevrolet Silverado 3500HD, with repair costs ranging from $800 to $1,800.
