Hi so first like before it was running and working with SM CH codes but after the dealer did diagnostic they made it stop working. Getting ideas from friends they were also saying sensors, wiring, but shocking part is, it went in the dealer perfectly drive able and when they were done with it just stopped working and the EE code appeared. No other codes or lights. The air in tank gets full, no leaks. Someone said they stopped on purposely so they can charge a good amount to make money. so first i will make sure to check the speed sensors and battery terminals for the transmission. Is the In line fuse right on the battery? Is there any other steps to check after i done all the listed things above?

after i do that is there anything else that i can check for?

HI im new to this. I was wondering if i can get help. So bit of a story. I bought a kenworth with a ZF Transmission its 12 speed automatic couple months back. So when i got this truck the transmission wouldn't get out of neutral until it hit the 2 hour mark of being warmed up. On the dash it started displaying the code SM and CH on the ZF gauge. I took it to the dealer to see whats going on and they messed everything up. Now the code EE displayed and the gear light F N R doesn't come on. No longer goes into gear. My question is for anyone that can help me figure out what the problem is or any ideas of what I can do. Thanks, anything helps.
