Locally, someone is selling a TH400, and here are the specs. I was wondering if this is all I needed, and what questions I should ask before purchasing it. Also, does this look like it'd hold up nicely to say 550-600rwhp?

I sure would appreciate some people's input on it - thanks!

Transking Stage 3, Manual Valve body, short tail TH400
For you 4th gen F-body guys, I also have conversion parts to allow installation in late model Camaros or Firebirds.

M-6 Crossmember w/ welded on spacer from Spohn, Includes poly trans mount & Crossmember/spacer/mount

Dipstick tube and stick, from SS454 truck. Already bent to fit 4th gen f-body
Steel driveshaft built by NW Drivetrain, setup for the above TH400 in a 4th gen

With the crossmember assy, dipstick/tube, and driveshaft, all you'd need to install the TH400 into a 4th gen f-body, would be a torque arm that does not mount to the tail of the tranny. The M-6 crossmember is already setup for a Global West Torque arm, but others like the BMR would work too.

Tranny has about 10 strip passes on it and approx 5k of street use. It was in my Camaro for about 3 years, which was primarily a weekend car.

What is a stage 3 build? Trans Brake,upgraded internals? need details.

 

If you want to keep the speedometer you have to buy a VSS for about $150 or so. You will need a torque converter as well. Cant use the 4L60e converter.
Its a reverse manual valve body, correct?

 

I'm not sure what is included in the stage 3 and not sure if it is a reverse manual valve body either.
