Re: [Amc-list] 4 speed Automatic 2wd Aisin Warner Trannies

[Wrambler242@xxxxxxxxxxx]

It's dirt simple to make a controller to place the trans in 1st or second and get it to hold.
It's totally electronic. A couple of switches will do the trick.
Frank uses a rotary in his with no TCU.
You might want to use some diodes to keep from backfeeding the tcu.
