nah, I wasnt going to mess with it for WOT preformance but Ive seen where some recommend just setting the min. in the tables to 50 mph. Im assuming just so it locks in 4th only?

 

It looks like this



Tow/haul is just another table like the one above with different values. Tow/haul unlocks the converter more readily (at a lower throttle) and waits longer to lock it up.

 

Ok cool really helpful
I know when ppl diesel pull u can fix a switch so u can flip it on then toward the end at spin out flip it off and will give few more inches but that's lil bit different use and concept

 

Thats basically using the locking action of the converter to put more force to the tires....it will only last a short time (time for the converter to lock, less than a second) and is VERY hard on parts, especially with something as powerful as a diesel.
