700R4 has two different sets of valvebody/case gaskets. The set you need must have the holes near the back of the case for the auxiliary valve body. If you installed two "V" gaskets, you will have many hydraulic problems.
I stand by my statement regarding the pressure regulator valve.
The trans will work with it ground off, but it will work fabulously better with the land intact.
Try contacting transmission shops for a distributor name for the parts Transtar sells. Then you can get the Sonnax valve.
Also Sonna has a 800 number. 800-843-2600.
