Allison trans. shift issue
Hello this is my first time here and post.
My 97 Newmar with 300 Cummins and Allison 6sp. just developed an issue tonight once I pulled into a campsite. It made a slight pop sound as I pulled in. I stopped and shifted into neutral. Then attempted to shift into reverse and got a flashing code on the shift indicator pad once I released the key pad reverse button. I tried to shift back to neutral and then into foreword without any luck. The key pad stated 6th gear so I tried to manually shift it down to first which the indicator said I was in but it did not shift into gear. I tried turning off the engine and restarting with out any luck.
Anybody got an idea what may be the problem?
Never had an issue with it before.
