99 Discovery won't start!

[Riverwalk2]

We drove our 99 Discovery - Allison Trans with Cummings engine - on Wed. Sat, the "check trans" and "low air" lights are on, but the engine won't turn over. (it's in neutral with emergency brake on.) Have checked batteries and all fuses. Aux Start doesn't help either. Documentation tells what to do if "check trans" comes on after ignition, but not before. Any ideas? Hoping this is something simple. We're newbies, but have 4 experienced RV'rs - including a mechanic - stumped.

Welcome to irv2. I've moved your post here to get some Allison owner input. Here's a link to some previous posts on this that may assist.

Ah ha! Mechanic crawled under and tapped the starter - it works!
