Vibration help please. I’ve read all the forums

So I have an 07 Tacoma auto trany and I am the original owner. It has 200k on it and it’s first problem has just started. I get a vibrating when I accelerate and it usually happens around 30 mph. I also feel it (much less noticeable, it feels like hitting the washboard part of the freeway) at around 50mph. It does it only when it cycles through all gears and in D. If I manually run through the gears or leave it on 4 it will not do it. It does it in 4WD warm or cold doesn’t matter. After reading all the forums I got the u joints and driveline overhauled. The tires are balanced and get rotated regularly. I had the trany flushed about 50k ago. Also had the rear leaf springs changed with warranty work about 5 years ago and haven’t had a problem until recently. I hope this gives enough info for your input! Thanks In advanced.

 

Sounds like the torque converter is on its way out.
