I would have to read every code to find out what codes would command high line pressure to be sure. But off hand most of the trans codes will default either to a high line pressure or default to a second gear start. For instance on some Buicks a bad alt will default the trans into second gear start. If you want I can research what problems will affect the trans when I have time.
Hey Peter I am rebuilding a 2003 GMC Envoy trans that was low on fluid. The only damage wa to the friction material to the clutch packs. This damage only happened after the trans was one gallon low on fluid.
