So turns out its the black heater hose tee leaking now. Son of a @#$%^&
I replaced both heater hose T fittings this past summer, they were definitely OEM fittings.
They looked like they were getting very brittle and I am really glad I replaced them before they failed.

And, yeah it does suck that you would need to reprogram the TPMS sensors for your winter wheels when you swap them over.
My scan tool will do it so I am covered should I ever decide to use winter wheels - which I am very much leaning towards doing next winter.

Out with the old, in with the older… just about finished swapping in the 4l80e. Just waiting on the harness adapter and tune. Lost 3rd in the 60 so it was time.

first noticed a every so slight womp womp womp cruising 80 on the interstate few weeks ago coming back from a quick trip. no one else on the truck could hear it. now I can't not hear it anytime over 60 and it's quiet. if it's driveshaft I'm going to cry lol and then seriously consider a can of gas and a match.

I have hopes it's something else, but I know it's not. blah.


on a side note, is there a way to disable the rear ac controls with the automatic system? a child lock out would be nice haha.

you can sync the rear to the front or turn it off but no lockout like there used to be on the 800's
