Never had one of these transmissions go out on me, but I am thinking mine is giving out after 206,000 miles. The truck is shuddering and vibrating pretty bad in drive, lessens a lot or completely in neutral, and also lessens once the truck is being driven for a while. Feels slightly bogged down. Wondering if these are the signs of a failing 45rfe.

 

I am leaning towards a bad torque converter.
