4R100 UPDATE DETAILS

• Updated Machined Center Support & Sonnax Anti-Wear Case Snap Ring corrects common issues with movement between the center support and case causes wear on the rear of the center support where it contacts the case lugs allowing movement in the center support resulting in failures of these components and the forward clutch. The steel Sonnax support ring installs between the case lugs and the machined center support, giving more contact area with the center support, alignment of the support, and eliminating future wear at the support increasing durability
• Updated Spiral 4th Clutch Snap Ring corrects common issues with the 4th clutch piston retainer snap ring coming loose in the groove and destroying the front portion of the transmission. The spiral features a unique design that mechanically locks tabs into place, preventing it from being worked out of the retaining ring groove.
• TransGo Updated steel Valve kits correct common issues the original aluminum clutch line regulator valves have such as shedding the hard plating on the ends, scratch the bore and resulting in sticking valves, causing burned clutches and missing shifts. We replace these failure prone valves with new hard steel valves and correct these problems.
• TransGo Updated Pressure Regulator & Boost Valve setup allows increased line pressure and boost valve function
