shelby turbo 400 swap

Well the time has come to yet again do trans work to the shelby. After breaking a bunch of 6 speed junk I went to a c-4, that went good for a minute but still broke so now were off to the turbo 400. Hopefully this will take care of the problem.

Pretty hard to beat a TH400. Has anyone messed with the TH 350 in the mustang world?

What broke in the C-4?

Rossler Terminator 3 TH-400 works well for me.

We have used alot of turbo 400's in the shop and have had zero failures with them even at 1,000 horsepower.

Im still waiting on a failure report from pa on what broke , it took a crap on the two three shift and the input shaft looked like a candycane. It sucks changing transmissions because it had a lifetime warrenty. Im not sure about a 350 trans but I looked into a glide but was told my car is a heavy pig and was advised against it.
