1990 IROC-Z (350/700R4)

When I shift from 1st to 2nd my tranny shifts firm and quick... Same thing when I go from 3rd to 4th... However, my 2nd to 3rd shift is kind of sluggish and not at firm (it is NOT slipping)... Is this normal? Will the Corvette Servo fix this 'problem'?

-Thanks

 

It will help, but it will make 1-2 even firmer. The HD Trans-Go Shift will do a lot more, it depends on what you are trying to do.

i noticed the same thing... by my dad said that its always been like that... and i belive thats just another flaw in the thirdgen... the 2-3 shift was always weak. if there is a way to firm it up, other then trans kit, i would like to know... ah what the hell, im gunna get a new one soon anyway... trans rebuilds are inane, and id rather get a new one thats built next to my old one.
