700R4 Street/Strip Transmission 1988 & Up
700R4 Street/Strip Transmission 1988 & Up 
Street/Strip 700R4: Starting at the "Front Pump", new (late design) seal, Teflon bushing, 10-vane rotor/slide assembly, Trans-Go Hi-Rev steel rings & priming spring, special heavy duty pressure regulator valve, Trans-Go HD pressure regulator spring, .296 intermediate/reverse boost valve, .500 main boost valve, both halves of pump machined flat with rotor to pump clearance set at .002"-.003", and new stator support. This pump now will keep the pressure & volume up 7,800 rpm.

Reverse Input Drum: A new reverse/input drum, along with the Turbulator low-drag steels, and Borg Warner clutches. The Belville spring is replaced with a waved spring, this eliminates the Belville spring from eating the reverse/input drum and adding metal to the transmission oil.

Input Drum: New latest design 29 element input sprag, Borg Warner clutches for the overrun and forward clutch assemblies, 8 Borg Warner Hi-Energy clutches along with Kolene steels used in the 3-4 clutch pack, Trans-Go (Hi-Rev) heavy duty springs replace the OEM 3-4 and forward springs and 3-4 helper springs (the Trans-Go springs prevent the 3-4 clutches from getting into trouble, due to centrifugal clutch apply. Good for up to 7,800 rpm, clearance for the 3-4 clutch pack .045"-.055", a Viton input to output shaft seal is used, the Viton is soft (will withstand 650 degrees F.) and will conform to the output shaft thereby guaranteeing oil to the rear planet. A "dual feed" input shaft capsule is installed for a better torque converter clutch lockup.

Rear Drive Section: Hand picked input sun gear, forward planet with batwing thrust washers, input internal gear, reaction carrier shaft, a new GM heat treated sun shell, low/reverse support, the latest design Borg Warner low/reverse roller assembly, Turbulator low-drag steels, Borg Warner clutches, hand picked or new rear planet, hand picked reaction sun gear, internal reaction gear, internal reaction gear support, a bronze rear case bushing, new governor gear, and a Teflon extension housing bushing and a Vamac rear seal.

"2-4 Band & 2-4 Servo" Borg Warner Hi-Energy 2-4 band, new Corvette 2nd gear apply servo used in conjuntion with the latest design Viton seals instead of the oem teflon sealing rings. This improves the 1-2 & 2-3 shift.

Valve Body: We use the Trans-Go Performance Shift kit in conjunction with the large boost valves, Corvette servo, and the 8 clutch 3-4 pack. (This setup has proven to be very reliable). I work with the second accumulator and use the 937 housing from the late 4L60E's, to give the best possible 1-2 part throttle shifts, and progressively firmer shifts with more throttle opening. A Sealed Power (zero-leak) filter is used.

The Case: We use the 1988-1992 transmission to start our builds with unless a special request to do otherwise.
