TCIs trans brake valve body c-6

I keep getting a pop up for this valve body .Looking at the picture it appears to be an all new casting from TCI .The #421500 maybe they decided to get back into the c-6 game .Several years ago I called their tech. guy and he said their c-6 trans brake want any good so I guess we will see somehow I don't Think Frank has much to worry about though.Doug

Frank uses a specific VB from the earlier c6s. They are getting harder to find. I just bought one of his last ones for this year to keep a spare.

I had a TCI package with brake and it flared badly on the 2 to 3 shift. I went to a Broader Performance brake and it was a huge improvement. If you do change brakes make sure that you look into the servo drain requirements. TCI is closed, Broader is open.
