Can I datalog my trans shifting and converter lockup on my '02 Screw? I can't tell when my converter is locking and when I'm shifting into overdrive. I think they might be locking/shifting at the same time. While driving with o/d off, I don't know if the tc is locked, and when I release the o/d button, my truck shifts and falls on it's face bogging down. If I'm still accelerating when I release the button, it feels and sounds like it shifts two more times.

Will a handheld such as an SCT and my laptop plugged into the OBD port log those things. Thanks for any help.

 

Yes it will be able to see when the TC locks. I know my truck doesnt lock in anything other than 3rd and OD

 

Thanks. I'm pretty sure mines doing the same, and is probably contributing to my poor gas milage. Now to figure out how to fix it. Any ideas?

 

Unlocking the converter is a bad thing. Causes a excessive amount of heat in the transmission. I'm trying to find a way for my converter to stay locked longer
