I have a 95 LT1 with auto tran and want to find out the speed / RPM at which the shift from 3rd to 4th occurs at WOT. Thanks for any guidance.

Hi
my c4 the T700 used in early c4s they didn't shift into 4th at full throttle, have to back off the accelerator for the 3 to 4 shift.
Was a real disappointment at an airstrip top speed run event, having to take the foot off a little for it to shift to 4th. Then slowly accelerate to the point where it would not kick down to 3rd, then use full throttle in 4th.

Some say standard they allowed 3 to 4 with wide open throttle, I have never had that happen in my c4. I believe the 4th is to fragile for a wide open throttle shift, hopefully that has been solved in the later C4s cause it sucks.

On 1/4 mile runs its at that limit ... just, only where you have a chance to step on the loud pedal for as long as you like is where it shows up. Which we usually never get to do legally...

last time out I was at WOT and when I hit 120 MPH I was still in 3rd and I backed off.

Any later model C4 drivers that can guide me here?

thanks
