2 lubegaurds and still shutters

So i did a d and fill....added 2 shutter fixes from lubegautd to no avail...still got shutter on 50% or more take off and at 30 to 40 mph.....ima do a tranny flush at the dealer and add 2 more lubegaurds after.....im betting this thing needs a converter or another tranny and if thats the case this dealership i bought it from is gonna have a real problem with me.

 

I've read that there's a solenoid in the transmission that controls tc lockup. Let me look...

Edit: read through this thread.
