2009 Allison 4500RDS "Cateyes" jumps in and out of gear
in Engine and Transmission
Posted
I know this is an old thread. My dad also has an 06 international with a 4500RDS ALLISON TRANNY . It works when it wants to.... we’ve done a bunch of different things to it. Still, it will show a ol95 code’low sump temp’ and 5587 ‘ c3ps problem.... does anyone know what the 200100 adapter does? The Allison tech can’t even hook up to the truck. I think the brain might need recalibrated or I need that adapter! By the way, none of the codes that pop are valid. No problem with c3ps , got a brand new internal wiring harness and interior filter. ..... when it does drive it shifts perfectly etc... what does that adapter do? I know it updates old to new internal harness to brain. You think that could be my problem? Anyone ever heard of that? Let mee we know please, I’m all ears
