Hi....I am having a problem with my truck. The problem starts when the RPM's drop down to around 1100. When you give it gas a mild to radical shaking occurs as if in a standard trany you were shifting from 1st to 3rd gear. A complete transmission service by the dealer shows no sign of metal, burnt fluid, or any other tranny problems. The truck has 115k miles. Thanks in advance for the help.

Check the codes, check the coil on plug packs (cops) and clean the throttle body. Ignition system issues feel similar to tranny issues in these trucks...

That's 100% a spark plug issue! Exactly what mine would do...

It almost 100% your coils. And a little help of old plugs if u havent replaced them yet. Literally 4 days ago mine was doing the exact same and a transmission shop hooked it up to a computer and it was misfire in cylinder 2, so i replaced the coil and wala fixed. But im doing plugs within the next couple of days. Just find out which cylinder (s) it is and replace the coil very easy to do.
