Common Issues & How This Fixes Them
What happens when your Silverado’s transmission hesitates during acceleration? In my shop, I’ve seen over 300 cases where heat buildup or electrical shorts fry the TCM, leading to limp mode or no-shift scenarios. Symptoms include delayed engagement, harsh shifts, or dashboard warnings like “Service Transmission.”
Causes often trace to water intrusion near the LH core support or voltage spikes from worn wiring. This 24289415 TCM fixes them by integrating updated GM software that enhances shift logic and diagnostics.
