I am interested but I also have an 06 tr and mine never made a gear noise in first until it was ready to grenade on me, anyway what are you asking for this gearbox, these boxes aren't going for much due their weakness to handle power levels anything past stock, especially with a little agressive driving, I did my 6speed swap but actually prefer the longer gears of the 5speed, so I am looking to revert back to 5 speed and build the box so yours would be perfect.
