722.6/Nag1 valve body and transmission brake. - whipplem104 - 01-18-2017
Just wanted to let everyone here know. I currently offer modified valve bodies for high performance applications. I will work with your core or a new core. The modifications are 450.00 on a used valve body. I can get remanufactured parts for an additional 600.00 with no core return. So I can supply a unit for 1050.00. No solenoids or conductor plate. Those parts will have to be swapped.
On the transmission brake for drag racing applications this is a 3000.00 setup. This includes a new valvebody, conductor plate, solenoids, and modifications to the valve body for the transmission brake. Also included is the modified valve body mentioned above. Also a new pan and filter. The pan is a deep pan that is several inches deeper.
You will need a trans brake controller to use this properly and safely. It will not lock in 3rd or above.

Very nice! Been watching this on facebook.
What kind of difference is noticable with that modified valve body (without transbrake)?
RE: 722.6/Nag1 valve body and transmission brake. - whipplem104 - 01-19-2017
Available pressure in the upper gears is near double. So 2-3=3-4=4=5 are all near double available pressure for the shift. Also the main pressure from 2nd up is near 50% increase.
It makes a huge difference. We have taken a stock transmission in a TT jeep srt8 to a 9.6- 1,4 mile.

Ok, that sounds pretty nice. Will that also make that 3-4 flare tuning more difficult? That modified valvebody works with std solenoids?

It does not effect the 3-4 shift. I do still open up the port for k3 when doing them. I really do not have that problem with the newer generation tcm-2800 due to the way we are controlling pressures now.
