Transmission won't shift gear

[Packerfan316]

Hi there everyone. I'm having an issue with my 34 ft Land Yacht Diesel Pusher. I was able to drive it from my house just a few blocks so I can work on my skylights. However, now I'm trying to drive it and the transmission won't shift. I get the error code for the fuel sensor and relay. How do I clear these error codes. Batteries have 14v DC. Do I need to turn off the engine for a while and disconnect the batteries or is there something else I can check?

Welcome to the forum. If you have a scan tool, you should have the option to clear codes using it. It's a little fuzzy (been several years since I worked on one), but I seem to remember disconnecting the batteries for 24 hours will clear the codes as well. I may have that confused with another manufacturer's code clearing, but if I do, at least it won't hurt anything.

Mine is also a 1994 with Allison Model MD3060 transmission., We also had the same problems. Allison was great to have me dial the codes on the shifter while on the phone until they made sense. They diagnosed it and sent me to the local Allison approved shop for the correct repair. Call their 800 # and ask for Service Advice.
I'd give you #, but it's in my coach 600 miles away.
Turned out the ECU was bad and the new one cost $2172.99.
Now I'm doing rear brake calipers @ $593 each, rotors at $139 each and all new hoses. With shipping $1600 so far in parts, p;us two mew tires at $240 each.
Good thing I love it, because we've only got 1100 miles this month and the cost per mile is getting up there. However I know and trust the coach because I fix anything that needs it so it won't let me down on the road.
