Features
1. Application: Our 2nd gear super hold servo kit is the largest and most leak-free servo, perfectly compatible with Dodge Ram Chrysler Torque Flite TF-8 A727 (36RH, 37RH), A518 (46RH, 46RE), A618 (47RH, 47RE, 48RE) RWD transmissions. Replacement: Alternative to Part #22301B01K, S22905H, S22907K in terms of function and performance.
2. High Performance: Helps reduce the need for aggressive lever ratios, excessively high line pressure and other radical modifications to improve 1-2 & 2-3 shifts and achieve firmer shifts. Comparable to OEM part number 22301B-01K both in quality and functions.
3. Powerful Feature: The piston and cover is with improved sealing, the upgraded seal design conserves pump volume, offers more apply area than the original servo. Helps eliminate cross leaks and results in less leakage, Less leakage means there is more pump volume available for the converter to maintain line pressure.
4. Superior Material: Made of top quality Aluminum Alloy, Steel, Rubber and PEFE Teflon Seals, oxidation and rust resistance, enhance positive sealing and prevent case wear, ensures long-lasting reliable service.
5. Satisfaction Guarantee: If you're not 100% satisfied with our products, simply return it in 30 days for a full refund, with unconditional refund guarantee and 12 month's warranty.
