To install assembly, slip the retainer in place with the tangs toward the spring. Slip the spring over the small end so it comes in contact with the retainer. Push the entire assembly up into the pump. Push up on the booster sleeve and reinstall snap ring. Only use one in the rear servo. Use valve body gaskets supplied in kit. Governor tubes are not necessary, but one may be used to support early design filter and should be used if you have this type of transmission case.
Governor may be omitted. STEP Complete transmission assembly and install into vehicle. Be careful not to overfill transmission. Important Notice Do not shut down motor while in second gear with engine running at RPMs or above. Back to Installation Guides. Recheck pressure regulator valve assembly. Crisp shifts at part throttle progressively getting firmer with throttle.
Very streetable and very reliable. They also include all new friction clutches, bands, steel plates, soft parts, filter, modulator if applicable , as well as hydraulic upgrades, bearings added at several thrust locations, and other modifications depending on power level. Although we use the build levels and options below, each transmission is custom built for the application.
That is why we have a lead time. There are too many variations to try to keep these on the shelf. Call for a custom quote. Our Stage 1 TH is a heavy duty rebuild with valve body and hydraulic improvements, rollerized rear thrust, heavy duty intermediate snap ring, and OEM pan.
Aluminum Deep pan and additional modifications. Deep cast aluminum pan is standard. This build utilizes a new SFI case and bellhousing, aluminum direct drum, fully rollerized with several weight saving and drag reducing internal modifications, alloy input and intermediate shafts, alloy steel forward hub, billet aluminum transbrake valve body, and fabricated aluminum pan standard. Super Shaft large diameter input shaft is optional.
The Ultra — Low weight, low drag design This transmission is designed for the racer looking to maximize efficiency and reduce weight. Great for grudge racers, class racing, and anyone looking for that competitive edge. Parts breakage also becomes a real possibility, since the transbrake is going to shock the tires with near-maximum engine power right on the starting line. Installing a transbrake requires several internal modifications. It is best to install the transbrake while the transmission is being rebuilt.
Once equipped, the Turbo is a reliable and consistent dragstrip performer. Literally millions of them have been successfully raced since they were first introduced, and this relatively simple upgrade prepares the transmission for competitive drag racing. Drill Bleed-Off Hole. A bleed-off hole is required in the direct drum under the apply piston. Some drums have a check ball located in the drum, but the bleed-off hole is still required.
Deburr the hole and blow out any metal chips from the drilling process. Open Partition. Do not scratch or nick the bore where the brake valve is located. Remove at least 50 percent of the partition and clean the case thoroughly to remove all the metal shavings.
Remove Center Seal. Remove the center seal on the direct drum. No seal is used at the location shown. Install new inner seals and outer seals on the direct drum apply piston. Install Springs. Install 16 new gold-color springs on the direct drum apply piston, and install the retainer and snap ring. Set the clutch pack clearance to. Remove Band. Remove and discard the intermediate band and the apply piston in the case. They are not used with a transbrake application. Remove Seal. Remove both seals from the accumulator piston located inside the rear servo assembly.
Some seals are metal here. Some pistons use solid Teflon seals. Carefully cut them with a pocket knife and pull them out of the grooves.
No seals are installed on the piston during assembly. Install Check Ball. Smooth-Out Servo Cover. Make sure that the rear servo cover is flat. Attach a piece of fine grit sandpaper to a flat surface and gently work the cover in a figure-8 motion until it is flat and smooth.
Replace Modulator Valve. Remove the stock modulator valve from the case and replace it with the TCI brake valve and spring. Install Solenoid.
