ATP SMS-9 TH350 Master Repair Kit Plus (1969-1986 GM)

When you crack open a Turbo 350, the parts that decide whether the rebuild holds up are the frictions, the steels, and every seal and O-ring in between. This ATP master kit puts all of that in one box so you are not chasing individual gaskets halfway through the job. The clutch material is a premium friction that grips smooth and shrugs off heat, and the steel plates are cut to spec so the packs stack clean and shift without shudder.

Along with the friction and steel plates you get the full sealing package: the pan gasket, metal-clad seals, rubber lip seals, sealing rings, and the O-ring set, all vacuum-packed and sealed in bags so nothing shows up nicked or contaminated. ATP has been making transmission parts for over sixty years, and this is the kit shops reach for to bring a 1969-1986 TH350 back to stock-or-better condition.

One thing worth knowing from the bench: this covers the soft parts and clutches, not the hard-wear bushings. If your core has miles on it, plan to add a bushing set alongside this kit. Ships from the USA.
