torque converter locking and unlocking on highway
When im on the interstate going to work doing 65 and let off the gas to 45-50 then accelerate slowly it starts to stutter. Feels like it can make up its mind to lock and unlock. if i stomp on it it goes fine. only happens when i slowly accelerate. asked the local tranny shop and he said it the TC relearning its self. well its getting worse. it gets really bad afterwork on the way home when it hot outside. anything i can do? any advise please!

Sounds like TC shudder to me. When was the last time you changed the fluid? Old fluid can cause the shudder because its lost its friction modifiers.
Could also be the solenoid that controls TC lock/unlock. That solenoid is an easy fix too, its right under the pan on the valve body.
I would guess its either one of those, but if its not then your TC is prob on it's way out.

The solenoid is called the TCC (Torque Converter Clutch) solenoid. It's there to lock and unlock the TC. Like I said if this is your prob, its right on the valve body when u take off the pan. So its easy enough to swap out.
The TCC is the dark round object above the pink paint. When you take off the pan its easy enough to locate really.
I would take it to another tranny shop for more opinions though, instead of just throwing parts at it. Maybe they can confirm what problem you're having through tranny codes. Swapping the TCC is easy enough, but you would need a new one and new fluid.
