I have talked to most of the after-market tranny places, Art Carr, Level 10, Performance Automatic, and Lentech, and from what I can tell the clutches for the kits are made by Raybestos or Alto. The after-market guys just repackage other companies products. I am pretty sure the mechanical diode that the after-market guys sell is a stock Ford part. Um...there are a few other things out there that are repackaged too, just cant think of them. As I said with my Alto Red Eagle kit, the gaskets in there are packaged by Level 10. I still need to order a few things like the hardened input shaft, deep pan, tranny cooler, shifter, and fluid. Besides the input shaft, the rest will probably come from either Summit or Jeg's.
A question for RC, have you looked at how the shop hooked your tranny cooler up? Is the stock cooler still in place? If not did they just use rubber hose to connect the stock tubing to the new cooler? Thanks for any help you can provide.
