STEP 2. Replace the reverse clutch piston, and install the springs furnished in the kit. Discard the original reverse clutch springs.

STEP 3. Remove the wavy steel spacer if your transmission has one. Reinstall the reverse clutch pack. Try to get at least 5 friction plates into your reverse clutch pack. Check the clearance of the clutch assembly and make sure that it reads from .050 to .075 if possible.

STEP 4. Before installing the valve body, dip the special valve enclosed in some transmission fluid. Then install it into the valve body. There is no spring that goes with this valve so just push it into the valve body as far as you can, and proceed with the next step.

STEP 5. Replace the valve body with the one enclosed, making sure that you reinstall the low servo feed tube. After the valve body is secure, make sure that you do not over tighten it to the case. Check the manual valve to make sure it is properly engaged into the shifter linkage before installing the linkage guide plate.

STEP 6.  Install the Electric Solenoid enclosed where the vacuum modulator was. Make sure that you use a little spot of lock tight on the thread. These solenoids are a little heavier than the original modulator, which gives them a tendency to want to loosen up. Be careful not to tighten it up too much either, because the threads in the case are not that strong and also have a tendency to strip out or crack the case along where the thread boss is located. Please be careful.

STEP 7. Always check position of special value with solenoid in the applied position as well as the off position. In some cases you may have to grind special valve for proper clearance.

STEP 8. Install the filter and pan.

STEP 9. Adjust Band: To adjust the low band, release lock nut around the adjustment lug on the side of the case. Tighten the adjustment lug until it is snug using a short wrench. Then back out lug 3 ½ turns, and retighten lock nut.

STEP 10. To function properly, the electric Solenoid needs to be connected to the 12- volt supply using the best wiring procedures. Wiring is easy but for the best results please follow these suggestions. Attach one white wire to a good ground. The transmission case is NOT a good ground. Try to use a 12 to 14-gauge wire to attach the ground. NOTE: The electric supply to the trans brake button should come from your fuse panel in your car. Please, for safety reasons, use a 20-amp fuse in the line. Do not run the brake button off the same line as the line lock. Use an independent fused source only for your transmission brake. If you are using a disconnect on your wires, make sure to solder all of your connections. Terminals that are not soldered are just not good enough. For this solenoid to function properly, it must be installed properly.

Once installed, refer to the section on FILLING THE TRANSMISSION. This is a very
informative section so please spend a minute to read it.

 

Special things to know

SHIFT PATTERN: Park-R-N-2-1

REVERSE: This valve body is equipped with a very special feature to keep you off your roof at 100 plus MPH. In order to get reverse, you must first put the shifter into the reverse position, and then press your trans brake button. This procedure is intended to keep you from accidentally hitting reverse after you make your run. Some people like to shift their transmission into neutral after the run is over. However those who have had the misfortune of accidentally hitting reverse can tell you it is not a fun ride on your roof upside down.

 

 

FILLING THE TRANSMISSION

What You Should Know About A.T.F.
When filling the transmission with A.T. F., keep in mind these little known facts listed below. I’m sure that you will find this section informative and helpful.
While checking the fluid level of the transmission, keep in mind that the level will change directly with the fluid temperature. If the fluid feels cool, about room temperature, the level should be between the two dimples below the “add” mark. Dimples are on only some models. If the fluid feels warm, the level should be close to the add mark. If the fluid is hot, the level should be between the add and full marks. If fluid is added, recheck the fluid level after one to three minutes with the engine running.
Hydra-matic engineers note that automatic transmissions are frequently overfilled because the fluid level was checked when the fluid was cold and the dipstick indicated that fluid should be added.
As the fluid temperature increases, a level change of over ¾” will occur as fluid temperature rises from 60 to 180 degrees. Refer to figure C.

TRANSMISSION FLUID TIPS

It really doesn’t matter to me what type of fluid you put in the transmission as long as it is a high quality brand. My personal preference in my race cars is Mobile One Synthetic. It seems to hold up the best for me. Conventional fluids start to break down at 200 Synthetics hold up too much higher temps.

COLOR

A few years ago, transmission fluid becoming dark, indicated fluid failure. Hydra-matic engineers say this isn’t true today. DEXRON II turns dark early in its life; therefore, the color of the transmission fluid is not a good indicator anymore.

SMELL

Hydra-matic engineers say that smell isn’t always the best indicator of the fluid anymore, either. After a few hundred miles, DEXRON II develops a definite odor. Engineers say the transmission fluid should not be replaced prematurely just on the basis of its smell. Although sight and smell alone should not be used to determine the condition of the fluid, do not overcook these symptoms when making a service determination.
