th350 keeps breaking

[chikn305]

I have a th350m with transbrake and everytime I use the t-brake it breaks the low/reverse sprag. I'm wondering if anyone has some suggestions on how to fix this problem.

if you stage without the brake does it work?do you get wheel shake?wheel shake can brake it as well as a poorly designed brake valve body

Tranny works fine without the brake. There's no tire shake. Im starting to think its the valve body. I talked to the company I got the valve body from and they told me to put the sprag from a 700 in it it worked better but still broke. I got 2 runs off the brake this time but broke on the 3rd.

it is ertain to be the valve body.i know 2 other people that had the same problem with the same company,

I run a built T/3503200 con. Never a problem and running in the 10's.I do not run a transbreak though. I would go with a 400 if I used a break. Maybe only 15 horsepower loss or so but would not self destruct.

it is certain to be the valve body.i know 2 other people that had the same problem with the same company,

Can we ask what valve body this is? I am building a TH-350 right now and don't really want to have to do it again. You can PM the name if you want. Thanks

thanks for the replies guys. I was afraid that was going to be the problem. Any suggestions on how to fix or what valve body to use?
