2006 Cobalt Auto Troubles

Hello pep...
I have a problem with my Cobalt that has a 145k. The cars had no issue until yesterday when I tried to sell it. I drove it the location and the people jumped on and took them 20 min to test drive it. When they came back, the guy said the tranny is jerking. I said wooooooot... He said it jerks when taking off from 1st to 2nd only and when you come to a stop....and he was correct which I was shocked bc it's never done that. Cobalt jerks at taking off. Speedometer bounces only when coming to stop for 2 secs and driving again. That 2 secs make a jump to the needle. I check the trans output speed sensor for ohmmeter and it shows a 169.1 ohm. Turned the key on to check the volt and nothing shows. For the continuity nothing as well. How to tell if the sensor is bad?

You may find it easier and cheaper to just replace the sensor than to test it.
Check out “Hall effect transducer”
Or try
