A while back I was asking about small, light automatic transmissions and how would I control them if it went into a completely different type of vehicle.
Well here's how

Interesting, lets you turn an auto box into a tunable "tiptronic/sportshift" box. Too bad it only works with those 10 GM & Ford transmissions though.
I'm a bit surprised it doesn't list working with any of the GM transaxles like the 4T60E etc. Pretty cool though, pricing is reasonable compared to some of the controllers out there.
Now, how long before there's a megashift?

Transaxles are supported. A 4T60E accepts same electronics as a 4L. I just finished up a Compushift II install on the Camaro.
Now how long before there's a megaABS or a megaTCS?
Suddenly I want to play with my DD. I think with some creative logic/manual override I could get better mileage.
Has anyone used one of these on a lemons car with success?
I'm wondering if anyone has used one of this in ANY car with any success and how much trouble was it?
Which one of the transmissions listed is the smallest?
On the GM side the 4T60/65 is the smallest listed, but still huge. They had a 4T45, which is still way huge for what you are looking for. The Saturn trans (S-series) is probably the smallest GM auto (and still solenoid controlled in the same way) until the newer stuff like the Sonic. Maybe one of the Ford options is really small?
I didn't know all the numbers, but I'm suspecting all of them are for larger transmissions since I'd guess that's their largest audience.
Yes. Think of it this way: the 4L60 is what you would find in a 1/2 ton pickup. 4L80 in a 1 ton. It just goes up from there...
I don't see any reason you couldn't use the controller on a small trans that is still controlled in the same way though.
The controllers are cake. They all simply read TPS and/or MAP as load input and vehicle speed to determine shift timing. Manual inputs are as simple as ignoring the VSS. All in all it's way easier to master than EFI. Tuned right, there ain't no slush. And most of the manufacturers are super easy to work with.
Torque converter engineering is the hardest part of the equation and not cheap.
