diesel site has a billet multi clutch TC for $600.

My long term target is 400hp. D66 type turbo.

I already have a BTS valve body installed.

I can get a used Suncoast TC for $500. He swears the solenoids failed, that the TC is clean. Let's assume it is for the sake of this conversation.

I presume the diesel site TC is a 6.0 factory part...

I realize there are a lot more expensive TCs out there, but there are a lot of people making way more power that I am or plan to. Is the diesel site TC (or similar) a worthwhile upgrade for my stock trans?

 

Most of the 5R110W transmissions I have done, including my own started from a failed solenoid. The solenoids failed due to metal debris in the fluid that came from the converter.

I would not want to install a questionable converter, if the converter is making metal it could take out the pump as well as the solenoids, that will cost way more than your savings.

 

I don't know the mechanics of how the locking clutches are activated, but can see how a slow or weak solenoid could cause the clutches to wear. Thanks!

For my relatively mild HP goals, is this TC all I need? I also have a cooler that I'll be installing soon.
