Alright, so I’m having a problem where my transmission would normally shift fine after letting it sit for a few hours, but after say like 30mins- 1 hour of driving, my transmission would do hard shifts and stay in a certain gear and wouldn’t shift unless I do a complete stop, or it will be under power when I hit the gas, so I have to shift into second gear so I can pick up some speed. also won’t shift into 1st gear manually but will shift into second. Scanned it and said that my output speed sensor was bad so I replaced that and it still says it bad, but it seems like it made it better, but still acts up most days. Mind you, it will shift into all the gears manually or automatically at the beginning, and then all these symptoms happen after driving it for an hour or so. Maybe input speed sensor, shift solenoid, or dirty trans fluid? Please help, thank you!
