Thank you for all the advice. I went through a number of these recommendations. I’m thinking it’s not transmission related. I learned a lot from this advice.
As an example, with the engine idling I can hear the engine running rough. I changed the gas filter and run with ethanol free gas. When I pressed down on the peddle. The engine revs but it hits a wall, where it runs really rough and you can feel the engine shaking.
When I was driving the truck on Sunday it was running smooth and after a few errands (stop and stars) it started this issue.
The engine oil is fine and clean and at the right level.
My plugs where changed about a year ago. Oil was changed in the spring.
Open to thoughts....Not sure if I need to bring this to the engine forum
