New Extreme 4L60 Maximum Hold Servo Kit Corvette Style Billet 700R4 4L60 4L60E 4L65E

The New Extreme 4L60 Maximum Hold Servo Kit is a 700R4, 4L60, 4L60E, 4L65E and 4L70E complete OEM replacement includes both the maximum hold intermediate servo and the 4th gear extra hold servo.

The intermediate servo has the maximum fluid apply area that is possible and the 4^th gear servo has 11% more apply area than the largest GM version.

We recommend trying this servo alone PRIOR to installing any other shift modifiers or shift kits.

The New Extreme 4L60 Maximum Hold Servo Kit features:

• 6061-T6 CNC manufactured billet construction
• Unlike some super hold servos, this has added holding power without having to worry about floor pan clearance
• 2^nd gear has the maximum allowable fluid apply area more than ANY other servo piston on the market today
• 4^th apply piston features 11% more fluid apply area
• OE style PTFE seals create a positive seal without causing band drag
• All stock hard parts are interchangeable
• Increased holding power, more positive 1-2, 3-2, 3-4 and 4-3 shifts
• Can be installed without removing transmission from vehicle
• Piston seals ship already installed
• All necessary seals are included
• You will have to disassemble your original servo and reuse some GM components
• We also sell the other components of this servo separately, just ask

NOTE: We recommend that you replace your servo pin, as most of them mushroom over time. If your original servo pin is mushroomed under the E clip, carefully grind your existing one back to size – otherwise it will not go through the new piston. Modifying the piston out to fit your worn out pin is a bad idea, it will create a large internal cross leak and lower the effectiveness of the servo kit.

Our parts are recommended for professionals!  Install and assembly instructions are available for those who need it.
