We put together a nice blog post that covers Allison Transmission. This includes:

1) Free service/troubleshooting manuals
2) How to read/clear/troubleshoot Diagnostic Trouble Codes (DTCs)
3) How to reset the TRAN SERV light that comes on (Which is when your oil or filter needs to get replaced)
4) ... and a bunch more information.

Here is the link, enjoy!
