Transactions Transmissions

He has had my Sons truck for over two weeks going to
rebuild the transmission, called and told him it was
ready after a week, so my son picks it up. Gets 10 mins
down the road and it cutting off. Never done that
before. He couldn't keep it cranked. Son calls the shop
and the owner tells him..."I don't know buddy," my son
tells him it needs to come back and the owner says
"well if u can get it back!" I should have known better at
this point but my son gets it back there to his shop in
(the middle of no where ) this man has for another
week at this point and we go to pick up 4/14/22 and 10
mins down the road ... Rpm bouncing and shutting off
again and choking to stay on. Call owner he says some
bs about he don't know, he thinks it is electrical and
tells my son to unplug the brake line under the steering
wheel. This guy is an idiot. We got it to another
mechanic yesterday after noon and I will be pursuing
him legally. He called my son and cussed him out telling
him it was his fault and he was doing something to it
My son is 17 years old and I was driving behind him
He didn't do anything but trust this man knew what he
was doing with his 1994 Chevy truck And he didn’t . He caused more issues then originally what was wrong .
