Ok, so I've searched by butt of on this site, other Cummins site and the internet and can't find an answer to my dilemma.

What I'm experiencing is a very, very faint shudder that only happens twice once I come to a stop. It's extremely faint and it's only once I'm at a complete standstill. I noticed it just after I had the tranny rebuilt so that's what I'm thinking it could be, but if that's what it is, what in the tranny is causing it? I'm pretty sure the TC has already unlocked once I come to a standstill otherwise the truck would stall out. I don't notice any drop in RPM's when it occurs. I haven't really noticed a difference in performance either. Mods are in my sig. Any ideas?

 

It could still be the TC even though it is unlocked, it could still be slightly engaged and completly releases after you stop.

 

Interesting. Would that be considered normal operation or is that something you simply can't answer without more investigation?

 

I am not experienced with the autos for our trucks. Just what I know from my previous cars.

Maybe someone who knows our auto trans can enlighten you.
