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?
