i have some probs with my 700r4 in my bird. in normal driving it shifts just fine. no probs. but when im playin around its weird. when i shift from D to 1 at a stoped idle and accelerate at full throtle i have no probs but when i get to around 5000rpm in 1's ill go to shift from 1's to 2nd but even though i shift from 1's to 2nd the trany wont shift until i let off to 3/4 throtle. what is up with that. it hurts my times a lot because i have to let off on the gas. what can i do so i can shift from 1-2-d-od at full throtle without letting off. i bought a b&m shift kit but i havent installed it yet.

 

basically what im saying is that i cant manually shift the trany from gear to gear at full throtle. i have to let off to 3/4 throtle. what will fix that prob?

 

cant anyone help me with this problem?
