Level 3 Transmission

The INVINCIBLE (Level 3) 4L65E

Our INVINCIBLE series features all the components of our Level 2 (Pro Race) transmissions with these upgrades for added Strength and Durability. (Nothing but the best):

OEM five (5) pinion planetaries with a grooved sun gear for improved lubrication.

Specially prepared performance input drum assembly with reinforcement collar.

Molded seal steel pistons.

Raybestos carbon composite forward friction plates.

A set of 8 RAYBESTOS STAGE 1 PERFORMANCE clutches with new Raybestos steel plates for High Impact Durability and Super Hold on the 2-3 shift.

Borg Warner 29 Element dual cage sprag assembly, the strongest available.

The SONNAX SMART SHELL to eliminate stripping of the splines and breakage common in the factory sun shell, which causes no reverse/second/fourth gears. This piece is balanced to lower drive train vibrations.

Ultra wide carbon composite 2-4 performance band with reinforced pin area to prevent tear through. This band will take the abuse and the heat.

The SONNAX billet second gear servo for maximum second gear hold (It also limits 3rd gear 3-4 clutch accumulation to aid in the 3-4 clutch apply)

Sonnax Dual Piston Overdrive Servo (with the wide band to stand WOT overdrive if your PCM is set up to allow it)

A Thirteen (13) vane pump with hardened rings and a full-time lube modification, which assures maximum planetary life and cooling. Max line pressure is set at approximately 220 psi .

PerformaBuilt custom shift kit, a compilation of what we consider to be the best of several known kits and some unique modifications of our own.

Deep OEM pan and performance filter .

This unit also features many other proprietary modifications for performance and durability which help it achieve its unbelievable horsepower capabilities. It will take whatever you dish out and we guarantee it. You won’t find a better unit anywhere.
