    So the guy who's rebuilding my transmission has struck out trying to find a shift kit or manufacturer who sells heavy duty internals like clutches, bands, etc. Has anyone rebuilt their tranny with upgraded internals?

    Bout the only thing I remember for upgrades on the LS tranny... is a company that sells a pump alignment kit... and upgraded valve body springs. Possibly a valve body servo bore kit too.

    It's in a couple threads from about 5 years ago.

    IIRC... there is a version of the 5r55s that was used in certain year Mustangs. You might want to dig around and see if anything pops up.

      Searching posts here brought up squat, which is why I started the thread, but some searching on my Mustang Forums on the 5R55S & valve body springs helped me find these guys: Ford 5R55S Transmission

      Thanks for replying about the valve body - I don't think I would have searched using that part otherwise.

      Well... I found this... but I know there's more on this forum. It's an old "for sale" add... but it may give some info you are looking for.

      Transtar was the brand I was thinking of. I know they made a pump alignment kit.

      There website has changed some... and it seems harder to navigate now.

      A couple threads mention using an SCT tuner to bump line pressure instead of installing a shift kit.

          My 93 Octane tune has the tranny programmed for harder shifts & increased line pressure, but frankly, it's nothing close to a shift kit. But with a slightly beefier rebuild, maybe I'll get more than 85,000 miles out of this one.

          Appreciate all your help on this.
