This kit consiststs of the SHIFT RECALIBRATION KIT #24RSRK/A but includes a 86 / 87 Buick Grand National intermediate servo assembly.This servo is used to multiply the clamping pressure applied to the intermediate band on a 1/2 upshift.It is capable of handling power levels of up to 450 foot pounds of torque.

This kit consiststs of the SHIFT RECALIBRATION KIT #24RSRK/A but includes our in house CNC machined billet aluminum intermediate servo assembly.This servo is used to multiply the clamping pressure applied to the intermediate band on a 1/2 upshift.It is capable of handling power levels of up to 800 foot pounds of torque.

This is theCK PERFORMANCE manufactured performance Buick Grand National seperator plate.It will retrofit all GM2004R model  transmissions except for early 81 to 83 with hydraulic lock up control in the valve body.Revised circuitry and deleted passages improves shift quality and improve durability.

This is the OEM Buick Grand National intermediate servo.It will retrofit all GM2004R model transmissions improves shift quality by multiplying the clamping pressure applied to the intermediate band on a 1/2 upshift.This servo will produce a clean firm shift.It is capable of handling power levels of up to 450 foot pounds of torque.

This is our in house CNC machined billet aluminum intermediate servo assembly.It is specially engineered for the most demanding applications.This servo is used to multiply the clamping pressure applied  It will retrofit all GM2004R model transmissions improves shift quality by multiplying the clamping pressure applied to the intermediate band on a 1/2 upshift.This servo will produce a very firm shift as soon as you step into the throttle.It is capable of handling power levels of up to 800 foot pounds of torque.This is the largest servo of its kind and is engineered to provide maximum performance and durability.Easily installs with the transmission in the vehicle.

This is a remanufactured OEM Buick Grand National valve body and governor assembly.It will retrofit all GM2004R model transmissions.This valve body is assembled with and includes all the parts from our SHIFT RECALIBRATION KIT #24RSRK/A.

This is a remanufactured OEM Hurst Olds valve body and governor assembly.It will retrofit all GM2004R model transmissions.This valve body is assembled with and includes all the parts from our SHIFT RECALIBRATION KIT #24RSRK/A.

This special package includes everything you need to transform  the GM2004R transmissions hydraulic system for  high performance street and strip use.This easy to install package was engineered to be a cost effective direct bolt in for all transplants and most high performance buildups. A carefully selected valve body core is remanufactured and assembled with  the components included in  our SHIFT RECALIBRATION KIT #24RSRK/A. Re-engineered springs for the accumulator valve,line bias,1/2 accumulator ,and 3/4 accumulator,and an updated 3/4 accumulator piston introduce a throttle sensitive accumulator and pressure rise system that meets the demands of high output engines.This reduces friction element failure and excessive heat build up during and after ratio changes.This allows the shifts to get shorter and firmer as the throttle is opened,resulting in clean ,positive gear changes at small throttle angles and short ,firm shifts with larger throttle angles.A new AC/DELCO seperator plate is properly orificed to increase the flow of oil to the friction elements.A remanufactured governor is assembled with a combination of weights and springs to provide wide open throttle upshifts between 4800 and 5000 RPMS.This valve body can also be shifted manually and will hold 1st, 2nd,and 3rd gears to any rpm.New .500" TV boost valve,and .296" intermediate boost valves and a heavy duty pressure regulator spring significantly raise transmission mainline pressure to increase clutch and band apply pressures.An OEM Buick Grand National intermediate servo improves shift quality by multiplying the clamping pressure applied to the intermediate band for even greater improvements in shift quality and durabilty. This kit will retrofit all GM2004R model transmissions and includes all the necessary gaskets and instructions.
