Hello, I bought a 2018 Isuzu Npr-Hd V8/Gas with 82k miles at an Auction.
It's wrecked in the front of the Cab.
I believe it has a 6L90 /Double Overdrive. The Truck won't shift into any
Auto-Transmission gear's at all. The dash shows it shifting, sometimes the key gets stuck after turning the engine off and putting it in park. Other than the possibily the Transmission needing rebuilt, does anyone had any simular experiences and have any ideas.
Thanks
