Chevy Colorado / GMC Canyon 45K Mile Transmission, Transfer Case, & Axle Service. In this video we are going to do the 45k mile "severe" service on my 2017 Colorado. Under ordinarily driving conditions this maintenance is due at about 90k miles. I'm doing this service earlier than what is required because maintenance is far cheaper than replacing parts. Also, the shift quality in my 6L50 transmission has started to decline slightly. This service made the transmission shift better than when it was new.

This video is going to cover, how to change the transmission fluid & filter on both the 8 speed transmission ( 8L45 )and the 6 speed ( 6L50 ) transmission found in both the gasoline and diesel Colorado and Canyon. The transmission fluid that I used is the updated TSB replacement fluid to help fix the torque converter shutter problems. We are also going to change the fluid in the transfer case, as well as both differentials.
