Make sure you have the proper amount of tranny fluild in it and get that Valvoline fluid out of it. Allison transmissons have there own type of tranny fluid and you want to use it. You can buy the right stuff from a Allison dealer. Most Detroit Diesel dealers are also Allison dealers. Look them up in your phone book and they will tell you the quanity and sell you five gallon pails of the fluid. Just get the serial number off of the side of the transmisson before you call. Change the fliters again too. Believe me, this is important. My company has Yard horses with Allison transmissions and you don't want to screw with the small stuff. Service them right and they work as hard as you want.

Depending on what transfer case model you have,some have one sensor and some have 2.They will both be on the back of the transfer case.They will be on the tail shaft of the transfer case.The one with 2 sensors has one on the left and one on the right.Hope this helps.Good luck.
