I have a 200 camaro with the 4l60e tranny.The car drives geat and gets every gear...I have a ss4000 stall and 4.10 gears. I driving it normal it gets all gears...But at WOT it pulls, i let off and drop down to cruising speed (50mph) but if i try to go faster 55 and up it starts to jerk bad like if there is a cut in fuel pressure. I turn off the car for a while and turn it back on.Drive it around and its fine, gets every gear and i can drive it up to 80 no problems.It just started a week ago and been having the tranny for 2 years.Tranny is built and has 2 tranny coolers it has full oil...............ANY IDEA WHAT IT CAN BE

 

I do not understand what you mean by "it pulls".

Putting a fuel pressure gauge on it would not be a bad
idea but you would have to cobble something up to be
able to read it in the cabin at WOT. I attached a SW
fuel pressure gauge and Kavlico sender to my cheapo
Actron pressure gauge to do this.

 

Jimmy I think the issue might be with the TCC from the way I read it.
