I'm having this exact issue, sometimes before I'll turn the truck off and then back on and it'll clear itself but now it's stuck doing the hard shift from 1-2nd, can I just replace the TPS and fix the issue or is there some certain way to set it?

Yea the in tank pump is running

For the first time, my truck been sitting for almost 4 months, the truck wouldn't start so I bled the fuel system from the final filter and it started right up, I let it idle for about 15 minutes and then turned it off and started it back up, after that I turned it off again and then...

Yep, that's basically the same leak I got

Does anyone have the NAPA part number to the oil cooler seal/gasket and the oil filter housing gasket? I have a small leak around the oil filter when the truck is running. I changed the oil cooler line about 2 years ago and the leak finally came back, I prefer to just replace the seals instead...

Crazy enough, I actually haven't had an issue since the few times it had done it back then

Had this happen as well, you should look into the viscous fan clutch, much better setup

I open and close the valve on the inside and here's a picture on the outside valve. It seems to be functioning correctly but I'm not 100% certain

Will check when I get back home, where is that valve located at? I don't remember seeing it anywhere before

Yea I pull the cable knob inside and still the same

Possibly, I was thinking the lever going to it may have snapped

The best fix is going to a viscous clutch fan, best upgrade I ever did to the truck

2002 M1123 I changed out the heater core and blower a year ago since the previous one had a bad blower motor and I was doing the whole coolant system over at the time, I finally decided now to fix the heat on the truck so I can have proper defrosters but the problem is the heater doesn't work...
