need help ASAP on making automatic shift manually

i just finished a new race car, its a 2006 ZX5 with an automatic. i need to make it shift manually so it quits shifting at the wrong times. ive done this on Dodge's before wiring switched into the transmission harness, and im assuming theres a way to do it on most newer electronic transmissions?

on a side note, a friend that i race with has a Ford Escort ZX2 and he read on a forum to just disconect the wiring harness and it will do what i want and also raise the line pressure. well he did it and it worked great on his car, i dont know if thats something i should try or can it risk damaging stuff?

Have you considered just changing the shift parameters in the tune?
I think if you unplug the harness from the trans, you will have no transmission function at all.
This trans is 100% electronic control, all solenoids, not springs and hydraulic pistons.

right, so a "manual" valve body won't work in this case/is not available.

I believe you could manipulate the solenoid by wiring specific ones but it would take a little bit to figure out exactly how to tie it in with, say, a ratchet shifter.

A tune should do what you need , you can set shift RPM and PSI to do what you want

thats what i did on my dodge ram diesel, toggle switches to shift, and torque convertor lock up on a switch too which is awesome because i can lock it and bang through the gears




Ill try to post some pictures of my new car

So what did you do to this race car to finish it? What about it is race car or are you just saying the tuning is stock?

That is pretty sweet, how rough is the landing when you get that much air?

I would get with 1turbofocus and see about some tuning. Changing the shift points is what you would need and he'd be able to help with that.
