The TCM (transmission control module) on your Allison Transmission is packed full of features. Get to know them. Do the research. Learn how to change from performance mode to economy mode. How about manually shifting with the up and down buttons? What about error codes and fluid levels? You can check that too.
I don't want to write a long boring post about the features of the TCM, just letting people that don't know about it understand that there are far more features the average owner knows about.
I doubt this is something most, if not all RV dealers would show you during a PDI. Maybe some do, but...............
I didn't know much about it either, but I do now. The more you research, the more you learn about anything.
Hit the Road and push the Buttons!
