i've got a 3200 circle d 278mm stall on a built 4l60e in my truck. right now my settings are no lock up except 4th gear which starts around 42mph. i'm shifting into 4th at light to no throttle in low 30's.

i'm wondering about changing my settings to make city driving a bit better. my thoughts are enabling tcc lock shift, and bringing in lockup in third gear for light throttle only then pushing my 4th gear shift point somewhere around 45mph. i'm hoping to adjust it to only allow this to happen on light driving so say above 10-15% or so throttle there's no lock up until 4th.

any thoughts on whether or not my truck will like this and waste less fuel on slow city roads ect.?

thanks

 

I'd recommend push for 3rd lockup at 22mph and 4th gear disabled until 35 (then enable lockup) with light throttle.

I enabled 3rd lockup at 20mph and 4th lockup at 31mph and it runs well at those speeds but it's a bit aggressive for some people.

 

so it should be okay to setup like this and enable my shift lock?
