Hey, my 98 k1500 has a 350 w/ 4l60e. The other night my truck clicked when trying to crank. On multiple attempts. Then I got home put in park and shut it off then crank it back up. When I crank it, it started to surge in idle. Now I’m getting low gas mileage, my tranny won’t shift to fourth and it’s delaying my shifts. Do y’all think this is ecm/pcm related. If so do I need to reset or buy new?
