PROBLEMS!!!! 4L60E not shifting at WOT
Guys please help i?m so freaking frustrated with this truck!!!
It?s a 2005 Chevy Colorado 4x4 I installed a 5.3 LH6 w/ Texas speed cam 212/218 600 lift. The trans is a 4L60E with a 2200-2400 stall. Tire are 33/12.50
The problems i?m having is the truck will not shift at WOT also it will not go into lock up on the converter, I can command it to go into lock up but when i do it starts to surge. I?ve watched countless videos on YouTube about the not shifting at wide open throttle and I?ve tried them all. I live in Virginia and it?s so hard to find a good tuner in my area.
Any Help would be awesome
Thanks
