Hello,

I appreciate everyone's help on here over the last year or so. I wish I was better at this and able to help out more. I have attached my tune for you to take a look if possible. I really like the way the jeep drives and runs. The one issue I have is when it is wide open the 1-2 shift is slow and sloppy. At normal driving it is a nice crisp shift, but not tire barking crisp. Can anyone please assist with this? 1979 CJ with 2007 LQ4, 4L60E w/2200 stall, 5:13 gears, 38" tires.

You could try lowering the normal shift speed down from where it's at. Set it to match the performance table, .300 is just fine for a stock 4L60e. Also you could add 5-10% shift pressure from 0-500 ft lbs on the 1-2 shift to improve it aswell.
