LS1/4L60E Pro Street Elite 1998 & Up
LS1/4L60E Pro Street Elite 1998 & Up 
Starting at the "Front Pump", new (late design) seal, Teflon bushing, 13-vane rotor/slide assembly, Trans-Go Hi-Rev steel rings & priming spring, Trans-Go HD pressure regulator spring and bumper spring, Trans-Go .532/.500 boost valve. Both halves of pump machined to achieve rotor to pump clearance of .002"-.003". A new stator support with extra wide stator bushing and a Teflon rear bushing. This pump now will keep the pressure & volume up 7,800 rpm.

Reverse Input Drum: New GM reverse/input drum, includes "drum saver" waved steel, along with the Turbulator low-drag steels, and Borg Warner clutches.

Input Drum: I start with a new LS1 input drum. The stock input drum can start getting into trouble at around 550 - 600 HP. I rework the input drum in the overrun piston area by adding a steel sleeve and special machining of the overrun piston and a reworked forward molded rubber piston to go along with the modified overrun piston to prevent splitting the drum open from high loads. New latest design 29 element input sprag, Borg Warner clutches for the overrun and late design Borg Warner forward clutch assemblies, 9 or 10 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 .020" -.035". New 3-4 and modified forward molded rubber pistons installed. Turbulator overrun steels are added for a slight gain in gas mileage.

Rear Drive Section: Hand picked input sun gear and forward planet, input internal gear, reaction carrier shaft, Sonnax Smart sun shell, 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, Teflon extension housing bushing, and a Vamac rear seal.

2-4 Band: Alto Carbon lined extra wide 2-4 band with re-inforced anchor pin area.

2nd apply servo: Sonnax 2nd gear apply servo used in conjunction with the latest design Viton seals.

4th apply servo: Sonnax "dual piston" 4th gear apply servo with the latest design seals for extremely quick 3-4 WOT shifts when needed.

Valve Body: We use the Trans-Go Performance Shift kit (modified) in conjunction with the large boost valve, Sonnax 2nd & 4th servos, new modified separator plate, and the Borg Warner Hi-Energy 9 or 10 clutch 3-4 pack. (This setup has proven to be very reliable with the higher horsepower). Highly modified Second accumulator setup to give the best possible part throttle 1-2 shifts, and progressively firmer shifts with more throttle opening. Sonnax pinless accumulator pistons used in forward and fourth. A Sonnax reverse abuse plug, spring and valve seup is used along with the HD 2-3 shift valve to improve the 2-3 WOT shift when using "D" shifter position. Modified 2-3 shift circuit is added to improve the life of the 3-4 clutch pack at WOT. Transmission is setup so it can be manually upshifted, or left in "D", or "OD" when raced. A Sealed Power (zero-leak) filter is used.

A Cryoed output shaft is used in this transmission for added durability when putting out over 750FWHP.
