the new trans has NO electrical connection, so no wires, relays or solenoids. This is part of why i am stumped!

the only connections between trans and car: bellhousing bolts, converter bolts, TV cable, shift cable, trans mount and driveshaft, ground wire. And yes, it is a braided steel ground wire.

we purposely picked a non-electronic trans as next year out comes the 305 and in goes a 350, so we are tossing the computer and figured this would be the simpler, more foolproof way.

Apparently not so foolproof!
