TLAV transmission won't upshift from 1st
We (Ontario Regiment Museum) have acquired a TLAV. It has a Allison X200-4B transmission with is modern enough to be controlled by an electronic transmission control module. It won't shift out of first gear. The fluid level is ok.
I know from having problems with modern automotive transmissions that the TCM diagnostics are usually very good, so I think our first step should be to find someone with a scanner we can borrow to see if there are any codes stored. We'll be calling around but I wondered if anyone on here knows if army repair shops typically have these scanners in their toolkits?
