Description
For the enthusiast that wants the best of everything, we designed the perfect 4L80 reverse manual transbrake valvebody.
No ECU control required on this kit, only the 12V wiring for the transbrake solenoid. Full billet 6061 construction for optimized fluid passage design and instantaneous up/downshift performance. Integrated clutch supported overdrive sprag in R-1-2-3 ranges. Solenoid free TCC apply in 4th gear. Full engine braking in every range – low band apply, intermediate band apply. Fixed line pressure eliminates over-boosting issues and allows for stable converter feed. FITS ALL CASES – Early, Late, and Reid Super80. Proudly made in our shop in the USA from US domestic aerospace aluminum.
