Torque converter going bad ?

I have an ‘09 Tacoma, with what I believe MAY BE a torque converter going bad. It’s progressively gotten worse.

When in "D"(overdrive), shifting from 2nd to 3rd, and then from 3rd to 4th, usually regardless of speed or throttle, it makes a terrible shudder(similar to driving over a cattle guard). It does not do it if I manually swap it to "4". When the problem started, it would only do it every now and then, and it progressively got to where it does it 99% of the time.

If I give lite pressure on the brakes, while maintaining throttle during the shudder, it immediately stops.

On very rare occasions, it will hesitate when given throttle from a complete stop; that issue has not worsened over time.

I know it's near impossible to diagnose things over the internet, just looking for opinions.

TIA.

 

Did you ever resolve the issue? my 09 does the same thing. TSB replaced Drive shaft, u joints, rear leafs still has same issue that you did

 

Transmission/engine mounts maybe?
