Figure 1- The INTENSE Street/Strip Shift Pakcomes complete with everything you need!

The INTENSE Street/Strip Shift Pakis designed to give you crisp shifts under light to mediumthrottle positions, and very firm shifts at wide-open throttle. It is not designed to rip yourdashboard out, break your input shaft or destroy your transaxle drive chain (please see disclaimerat the end of these installation instructions). Installation should average one to two hoursdepending on your skill level. No special tools are required other than an inch-pound torquewrench.

The INTENSE Street/Strip Shift Pakis installed by removing the transaxle pan, then theaccumulator cover. The accumulator housing contains the 1-2 and 2-3 pistons that control therate at which fluid pressure gets applied to the clutch packs during upshifts and downshifts. Ourkit contains custom springs and spacers to create the ideal shifts for a mix of street and strip use.Shorter shift cycle times mean less time when the PCM retards ignition timing during each shift torotect the transaxle.

Installation Instructions:1) On level ground, raise and support vehicle by the frame rails under the front floor pan. The

frame rails are directly behind the rear cradle bolts. Use good quality jack stands to supportthe vehicle.

4) Evaluate debris in pan to determine whether or not a shift kit is a wise thing to do. Metallic

sludge on the magnet is normal. Slivers or fragments are not. The inside of the transashould not be discolored with sediment. Staining or hazing of the inside of the pan isindicative of clutch or band failure. Figures 2 and 3 are normal transaxle pan contents.Figures 4 and 5 are abnormal pan contents.

5) With the pan removed, you can now remove the filter. Be sure to have the drain panpositioned to catch fluid from filter removal.

6) Remove shift accumulator assembly from transaxle by removing the necessary bolts.Remove accumulator tubes and differential oil tube. Differential oil tube can be removed bypopping the retainer clip out, then coaxing the tube out.

7) With the accumulator assembly placed on a clean workbench, remove the remaining boltsand disassemble. Remove and discard the accumulator piston seals and accumulator covergasket. Using aerosol brake cleaner, thoroughly clean all components. Be sure to remove allmetal residue from the accumulator bores. Clean the rest of the accumulator and thedifferential oil tubes as well.

8) Inspect the accumulator cover for signs of damage. Figure 6 is an example of normalaccumulator cover condition. If an accumulator piston has deformed the area indicated, thenyour accumulator cover must be replaced before reassembly. These can be purchased atany G.M. dealership, by asking for part number 24205584.

9) Inspect the accumulator piston pins for excessive wear and/or damage. Both pins should besmooth and free of lips or recesses that would indicate the piston has been binding on thepin. Evidence of this warrants replacement of the piston(s) and piston pin(s) beforereassembly. These can be purchased at any G.M. dealership, by asking for part numbers24206857 (accumulator piston) and 24203979 (accumulator piston pin).

10) Prepare the accumulator bores by using the provided abrasive pad to scuff each bore. Thisprocedure ensures longer seal life due to increased oil on the bore walls. Using one piece ofthe provided sandpaper, polish the piston pins to remove any small scratches. Use the otherpiece of sandpaper to smooth the flat gasket mating surfaces of the accumulator cover andhousing. With these preparation steps complete, again THOROUGHLY clean all componentswith aerosol brake cleaner.

11) Install the provided new seals on the accumulator pistons. Thoroughly lubricate the bores andseals with the lubricant provided.

12) Determine what size torque converter you have using the following chart:

1997-current Grand Prix GTP - stock torque converter is 258 mm

1997-current Regal GS - stock torque converter is 258 mm 1997-current Bonneville SSEi - stock torque converter is 258 mm

1997-current other applications using the 4T65E-HD transaxle - stock torqueconverter is 258 mm

All known aftermarket torque converters for these vehicles are 245 mm.

1998-current Grand Prix GT - stock torque converter is 245 mm.

1998-current Monte Carlo - stock torque converter is 245 mm

1998-current other applications using the 4T65E (non -HD) transaxle - stock torqueconverter is 245 mm

All known aftermarket torque converters for these vehicles are 245 mm.

13) Figure 9 is the recommended assembly sequence for all applications with a 258 mm. torqueconverter. 2-3 is assembled as follows: pin, #3 spacer, #1 spacer, white spring, red spring,plain spring, accumulator piston/seal assembly, one flat spring spacer, #2 spacer, 2-3 shiftspring (large coils). 1-2 is assembled as follows: pin, white spring, plain spring, #3 spacer, #1spacer, accumulator piston/seal assembly, #2 spacer, 1-2 shift spring (small coils). Hint:assembly is easier if you use the provided assembly lubricant to glue the plain spring intothe piston before installation. Note: the four different sizes of cylindrical spacers arenumbered 1 through 4, with 1 being the shortest and 4 being the longest.

15) With your shift kit assembled in the bores, install the gasket and cover and HAND TIGHTENthe bolts shown in Figure 11. Then torque them slowly and carefully torque these same boltsto 106 inch-pounds (NOT foot-pounds!).

16) With the assembly complete, lubricate both ends of all three tubes with the lubricant provided,and reinstall the accumulator assembly into the transaxle using the remaining bolts. It may benecessary to wiggle the accumulator a little bit in order to properly align the bolt holes andtubes simultaneously. HAND TIGHTEN the bolts shown in Figure 12. Then torque themslowly and carefully torque these same bolts to 106 inch-pounds (NOT foot-pounds!).

Figure 12 bolts that fasten accumulator assembly to transaxle

17) Install new filter and filter seal, and reinstall cleaned transaxle pan. Pan gasket can bereused. Torque all bolts to 120 inch-pounds (NOT foot-pounds!).

18) Lower the vehicle and ad six quarts of transaxle fluid initially. Allow the car to run untilcompletely warmed up. With the emergency brake engaged, and your foot firmly on the brakepedal, run the transaxle through all the gears several times. Then check the transaxle fluidlevel with the engine running and add additional fluid as necessary.

19) Once fluid has reached the proper level, go ahead and drive the car. The shifts should feelcrisp under light to medium throttle positions, and very firm at full throttle. Remember, theobject of this shift kit is to decrease shift times, and not damage the transaxle by slamminginto gears.

20) Enjoy!
