I think you first need to figure out how to read an odometer. You've given three different readings.

That brown thing holds electrical wires. Are you sure it needs to be replaced because it is cracked, or is it benign?

Nice insult 😂 And that I learned that the brown THING is called a Wiring Harness.

Yes, it is. I'm about to install a new transmission. Thanks for your help.

I was been supposed to update.
Update December 13, 2022 & the end of my problems, Yay!

It's fixed & running great!

New: MAP, MAF, Camshaft position (intake & exhaust), Crankshaft, 1-2 shift solenoid, 2-3 shift solenoid, 3-2 shift solenoid, EPC/PCS solenoid, TCC lock up solenoid, TCC pulse w/mod solenoid, Transmission & motor oils with new filters, & VVT solenoid.

I WANTED to do ALL of this! I could've just fixed my main problems 🤷🏻‍♀️( changing oils & replace the crankshaft sensor) drive for 100 miles & be back on this forum🙄 but nope! I'd rather fix it ahead of time. It took me some time but I fixed my OWN truck💪🏻
