@Wranglerfix Wow, thank you so much. I know you can’t guarantee anything causing symptoms on my jeep, but does what I’ve described seem at all possible to be wrong/faulty computer related or am i way in left field to think this may all be solved? Lol.

I appreciate this and I will aim to get it in the mail today. Have a great day also!

It sounds like the ECM has the wrong software in it. We will know for sure when we get it in.
 
Your pcm was reprogrammed and on its way back to you. Please let us know when you get it installed!

Thanks,

@Wranglerfix just installed and took for a spin, jeep is running like a dream and all shifting issues appear to be gone. No more check engine light either. I cannot thank you enough! Appreciate it so much. Will definitely recommend you to anyone i come across experiencing pcm issues!
 
I had the same issue and just placed a small piece of black electrical tape over the upshift light. Blends in well enough that you'll never think about it again.

Keep in mind this is coming from a man who misses nothing-

- He has never blinked his entire life

- Chuck Norris likes to read Memes about HIM

- His hat alone has more experience than most JK owners will in their entire lives

That was a brilliant advertising campaign. I started a thread one time calling him “the most interesting TJ owner in the world”.
