Overdrive? - Idiot light

#1
AllisonMan! I am impressed. Been checking out this site, and glad to find my way to an expert. I've got two issues:
First, I have a '92 diesel pusher with Cummins 5.9L Turbo and AT545. Cruising at 60 - 65mph is 2200 - 2500rpm. Sure do need overdrive! I can only go faster downhill with the wind. Is there an aftermarket overdrive like Gear Vendors or US Gear or does Allison do something like that? :question:
Second, We just drove to Alaska and back (30 days) and went through several days of heavy rain on the way up. Ever since then, the overheat idiot light works like a guage. When the tranny warms up, it gives a light glow, and when we go over mountain passes it gets pretty bright. It's the Spartan chassis and dash. Any ideas :question:
Thanks for being there!
