Rumble Strip Type Vibration
I am getting a fast vibration when maintaining speeds at <55mph. If I apply or let off the accelerator it goes away. I just replaced the drive shaft which eliminated another vibration I had. I know I have one LH motor mount. Not sure if that is the culprit.
Any input would be helpful.

Lets also assume its never been done and I'm at 154k miles. I just bought the car so I do not have any reliable service history but I do know for certain it was never done at Lexus/Toyota. I have that history and it's thin at best.

It should fix it up no problem, do NOT let them flush it. It HAS to be a pan drop, filter change and pan/magnet/VB cleaning, then refill. Then drain and fill the fluid 3 more times.
If you flush it the trans may die.

How do I clean the valve body? How long should I wait before subsequent drain/fill procedures? Once it's all back together how do I get the level set correctly?

Repeat the fluid fill section 4 times or so before doing the memory reset/road test, no wait is needed at all/you can keep the car on the lift the whole time. For the road test I recommend you first gently accelerate from 0-80 twice then do a full hammer 0-130 for the trans to learn everything it needs to know.

No it's not normal practice at all since it takes anywhere from 2-4 hours to do it how I am saying to since you need to remove the pan/filter and then spray everything down with brake cleaner to remove the grey caked on film you will find there. Then you clean the pan out to perfection and get the screws prepped and do any repainting you need to do to the pan/screws. Then you put it back and do the initial fill, then start the car and fill till the overflow overflows and then get to 95*F after going to each gear for 10 seconds. Once at 95 then you final fill it/let the extra fluid flow out from the overflow and seal the pan then stop the engine, next you need to go into TS or something equal and command a VB replacement/shift offset relearn and finally you go drive the car.
