Allison Transmissions. How To Check & Clear Trouble Codes Without A Scan Tool.

In this video I have a Heavy duty truck with an Allison automatic transmission with a check transmission warning light on in the dash. I show you how to check and clear trouble codes without a scan tool. I also show you what to visually look for and common failure points that I have seen over the years that could be the cause of your check transmission light. It is an easy DIY that requires no expensive scan tools. Hopefully what I show in this video helps you save a lot of money. What should you check first? Watch and find out.

If you are unsure of what you are trying to diagnose or repair, please contact a qualified mechanic. There is nothing wrong with asking for help.
