Both cars are relatively simple. The Cavalier sort of just does what it's told. The Buick seems to be a bit more rebellious, maybe even a bit vindictive at times.

I am not a computer guy.

Could you just monkey with the speed sensor pulse
to trick the transmission on the Neon to shift later?

John, I'm thinking the short tires would mess with you. RPM would be up, but actual MPH would be down...maybe?

You would have to write a program to override the fill points on the element to increase the shift rpm, as well as engaging the converter clutch lockup...which can have anywhere from 50-300 RPM worth of slippage depending on driving.

If one really wanted to go the route of running an automatic Neon, I would swap in an A-413 from an earlier front wheel drive car, and do away with the electronics.

I would second that A-413 swap choice, you can make them live easily, and the gearing choices are there if you look hard enough. Just keep it cool to make it live.
