If you can help out a fellow Kentuckian with any expert advice that would be greatly appreciated. I will try and describe what has occurred since I bought this 96 k1500 a week ago. It has the 5.7 vortec and 4l60e trans. Thank you so much for your time.
I did some front end work (lower ball joints, front left wheel hub, idler and pitman) oil change, pcv, air filter an throttle body cleaning. had battery disconnected for over 24hrs by the way the battery is too small i think for this truck. Started it up the next day and test drove it and it did great. Then, suddenly, the next day I lost third and fourth gear. There was no slipping or other indication of a problem, and it still doesn't feel like a slip, it feels like it shifts into neutral instead. I think I got it to shift into 3rd once. I hit the gas pretty hard from a stand still and it shifted from1-2 but took a little long this time an then revved real high and went into third, i think.
