TCM Ground - U0101 code

Truck would not crank at all, after searching this site, determined TCM problem. Checked for continuity between pin 9 and 69 and no continuity detected.

I took a small jumper wire with alligater clips and connected the heatsink to the ground on the battery. Truck started up and I dove it for 2 weeks like this until i installed a used TCM.

Questions is - Why cant I permanently attach a ground wire to the heatsink to avoid the cost of replacing it?
