1968 Plymouth Barracuda Fastback (old school build with a new school feel)
I rebuilt an A518, 46Rh from a 93 D250 Van to put into the Barracuda. The trans had no reverse when at operating temperature. I found the the rear servo was chipped on the edges, and metal pieces made it through the trans, scoring the overdrive piston retainer. I put a new Sonnax OD piston retainer in, Alto and raybestos clutches, replaced all seals/bushings throughout, had to replace a planetary gear assembly that was overheated, and upgraded to thicker billet servos with stronger springs and servo support rings. The valvebody was in good shape, and working properly so I just disassembled, cleaned, upgraded some springs and TV, then did a few mods for firmer shifts. My TCI 2600 stall converter came in after ordering it 2 months prior.
