Serious question, has anyone else had a cheap scan tool lie about a transmission code?
I bought a $150 generic OBD2 scanner off a truck last month. It said my customer's Ford had a bad solenoid, so I spent 4 hours pulling the pan. Found nothing wrong. Hooked up my shop's real scanner, and it was a simple wiring harness chafe. Lost a whole afternoon and ate the labor cost myself. What scan tools do you guys actually trust for transmission work?

Cheap scanners often misread transmission codes, so you need a real shop tool for that.

My buddy's $40 scanner told him his transmission was fine right before it dumped all its fluid in a Target parking lot. The tow truck driver just laughed and said he sees it every week. Guess the cheap tool missed the "catastrophic failure" code.
