Hello
I have a 2005 with a 330 cat and a 3000 allison trans. The trans will not go in reverse. Thanks for any help.

Do you know how to extract the error code? Your owners manual should help... but if you press the up and down arrows you will get a code that identifies what the error is... There are ways to clear the code but that will not resolve what caused the issue...

You can also use your touch pad to check your fluid level... I strongly suggest you go on the allison web site familiarize yourself with how to check your fluid level and read error codes... This information will be invaluable in determining what you need to do next as well as providing information if your situation requires service assistance.

I should watch this post, I have the same trans behind my 3126b cat motor, sorry I can't help
