Because you are working on the transmission out of the vehicle and it has not been previously modified, note the location of the four check balls and remove them. I appreciate the help and look forward to the replies. Have you checked the tv cable adjustment it controls the line presure from the front pump as you open the throttle you pull the tv cable ond it increases the rail presure and also the shift timing whe you are crusing in 3rd gear stand on the on the pedel and see if it shifts down to 2nd gear passing gear I don't know what cam you are using for one.

This eliminates the potential for a leak at the suction tube or O-ring in the case. Use the same procedure that you did for the 2-3 shift valve: Remove the retaining pin, sleeve, boost valves, and factory pressure regulator valve spring. Most stock tubes have a single O-ring where they seal in the case.
The kit also comes with special gaskets with holes that work in conjunction with the custom separator plate. The retainer snaps in on the lower end and is easy to remove. Clean the valve body thoroughly with brake parts cleaner and blow it dry. This Tech Tip is From the Full Book,. What is the optimum range I should see at the carburetor? I will have to look back for receipts since my Dad past away last year and he would've been the only one who knew.
Install the modulator, hold-down clamp, and bolt; make sure to use a new O-ring from the kit. I have also removed the governor, but do not know what to look for to determine if the part is bad.

Because the adjustable modulator and the gold spring under the modulator valve play a role here, this kit provides a very broad range of control to fine-tune shift points for any particular application. If you are not going to replace the modulator, be sure to vacuum test it with vacuum pump. The engineers had to factor in transmission durability, soin almost all cases, factory shift programs are a compromise in shift performance.
Step 2: Install the clip for the low-control valve into the partition as shown in the instructions. If later shifts are desired after road testing, remove the gold spring. For the first few miles drive at various speeds; use light throttle only and move the shift lever to all forward positions. In most instances, a few light taps and it comes right off. The governor drive gear is plastic.
The red spring is for street cars and heavy-duty applications. Align all the holes very carefully. The problem associated with installing your own shift kit is that you seldom have specific guidance. Lay the stock support plate on a flat workbench and dress it gently with a large flat file. Any fluid present at the hose end is a telltale sign that the modulator is defective.
If the grooves show heavy wear it is best to get another pump. Once the S-link is installed, tighten the retaining nut, and then snap the spring spacer in place. Mileage on the engine since install is less than 10,000 miles the truck was not driven often, mainly car shows. The transmission still functions as fully automatic in the Drive position.

Even so, the load is not well distributed to the race, and engines with big power that is, torque can eventually explode the outer race, even the hardened aftermarket part. It was used behind an engine making around 500 hp and 550 ft-lbs of torque. Remove the bolt and slide the modulator out of the case.
Measure the apply piston, then machine off the correct amount of material to add one clutch and friction plate to your drum. Use a large flat file for mildly warped plates, just be sure the plate is flat and sanded smooth before installation. The red spring is for street car and heavy-duty applications. The pan may be stuck to the gasket, especially if a cork gasket was used on the last assembly. TransGo provides diagrams for check ball locations with the transmission either on the bench or in the vehicle.
