If you can do the job yourself go ahead and get the sun coast parts. Looked pretty solid during the rebuild of mine. Shifts real firm, maybe even a little to firm. Especially after the TCU update by Dodge.
I didn't see any options where ATS can do anything different with 5th and 6th gears. As far as HP #s. I believe that with Sun Coast's Sprag
this tranny can handle what ever I throw at it off the line. 5th and 6th remain to be seen.
