i have a Rossler stage 3 4l60e and a 408iron block and when i punch it and it down shift into 2nd then shifts into 3rd it bogs down what could be the problem

 

anyone have a idea

 

its shifting too early out of second? be more specific.

 

well i happens when im doing a highway roll and i punch it and it down shifts fine and when i shifts into the next gear it bogs down and the tach just sticks and at 4500rpm and doesnt go anywhere by the way im reving to 6500

 

could it be not enough line pressure????????

 

Sounds like a similar problem that my A4 would do occasionally ... punch it for kick-down, it would downshift, but then upshift, and go into this "holding pattern" for awhile?! To me it seemed like it would go to lock-up in 4th gear or something stupid?? All I know is that all acceleration would basically STOP. If I let off the pedal, it would "find itself" again, and everything would work normal again?? I don't know WHAT caused that, and barely know how to describe it!

...too late now, 'cause my tranny finally blew 2nd gear, and now I put a T56 in the car!

 

that sounds like what mine is doing

 

anyone know have any idea? need help figureing out whatas wrong

 

It sounds like the torque converter is locking up. I have seen this before. Try Ed Wright at www.fastchip.com. He is very knowledgeable on the electronics, and should be able to help you out on this.
