  I hear Ram’s ZF transmission is pretty bulletproof.

  I have A 2020 1500 5.3 8 speed. LTZ. Transmission problems since 60,000 miles. Started when I go to store in morning to get my morning coffee before work leave truck running get back in put it in drive/ rev no movement step on gas a little slams into gear. Put in neutral step on gas little shake then put in gear and gose. Shut truck off start .. ok now at stop light stop truck after a few seconds feel a little kick if that doesn’t happen stuck in 3/4 gear shut truck off wait few seconds and start usually ok again. If you down shift manually ok as long as you get into 1st before stop. If not it kicks . I WANT A NEW TRANSMISSION. Now I want a new truck it just hit 80,000 IDK IF ILL BUY CHEVY CAUSE THEY STILL HAVE THE PROBLEM AND REFUSE TO RECALL . Oh I’ve changed the fluid and filter 3 times now. And yes used mobile 1 not ac/delco cause it’s not meeting the requirements that mobile is did use ac/delco filter

  Of course refrain from political debate but I myself have very dismal hope for what is all going on up here every where we turn so I nodded my head when I saw this joke.

  I'm looking at carpal tunnel surgery on my left hand and lumbar fusion.
