Got a question for you and your 4L80-E set up:

TCC MPH Threshold, what are your settings?

Release
2nd 45
3rd 38
4th 38
Apply
2nd 50
3rd 75
4th 75

This is what mine is set at.....I am not sure if it is right or not for the new converter.

 

I don't lock in second and set the apply in 3rd and 4th at 50 MPH to help my fuel economy.But I'm running 4.56 gears.How's the new converter working?

 

Its ok, guess it will take some getting used to.

 

mine doesnt lock in 1st or 2nd. it locks in third under 50% throttle. and it just plain locks in fourth.

 

Hey guys, I have a question. Mine just plain locks in 4th also. It doesn't unlock by applying the brakes either. Does ayone elses do that? If I am steady cruising and let off the gas, then quickly get back on it it will unlock (as will any other vehicle on the road) but the brake signal doesn't unlock it.

 

mine will lock and unlock in third if i let off. but in fourth it stays lockd.
