Possible Allison Transmission overfill

Exactly my dilemma .... On all my previous tranny services, the stick and the electronic had always been the same, so I never questioned it. So this time when the electronic said it was overfilled and the stick said full, I questioned the dealer that did the maintenance. He said believe the stick ... so I've let it go since the service, but now I'm going to believe the electronics .... Thanks to all you guys that helped me out ...

Sounds like the dealer did not want to deal with it or he has a rectal cranial inversion. I would not go back but hey that is me.

There are three types of Allison repair facilities one that is authorized to change the fluid and filters, the next is one that can change the fluid and filters and do work on the transmission on outside components then there is the third type they can tear down and operate on the transmission or completly rebuild it.

I had a problem with the electronic check on my tranny and Allison took that as a serious issue and had me take it to a repair warranty dealer. They went over how to check the fluid with the stick so I would have a safe start (I already knew how) but they went over it a couple of times. They also stated that one should check the stick prior to running them when things get hot enough check the electronic test. The level on the stick will be up high I think above all marks. It is worse to run over filled than low within boundaries of course.
When I change mine I will put in 20 quarts and then check the stick then run it and check the electronic level and then add 2 quarts so far so good.

You should make the dealer remove the 2 quarts after all it is his mess up.
