2008 HINO 286 A - EATON ULTRASHIFT ISSUES

Hey guys my truck's transmission (Eaton Ultrashift) is acting up..First time when you start it will be ok and will shift smooth all the way to the sixth gear. When you come to stop (at lights or stop signs) it downshifts and will not engage anymore, have to turn off the truck and sit for about 10 mins.... (had to do this the other day at some traffic light ...not fun!! ) and Reverse will not engage sometimes.

Any help out there? Am based out of Atlanta.

I had a similar problem in a Cascadia. The problem ended up being in the wiring harness.
Also, These transmissions are air operated, so make sure your air pressure is good.

I agree above the wiring harness also gave a cascadia a problem I used to drive. How many miles on the clutch? It mite be time for a new one.

I would have the tranny scanned with service anger before replacing anything. If you do have any codes let us know.
