If you want parts shipped to International addresses you must fill out the International Shipping Cost Request form INSTEAD of clicking on "Add to Cart" so I can quote International Shipping Rates

I will combine shipping if you order more than one item.
PayPal will add each item's shipping charges, but I will refund excess shipping charges based on how I can combine items to minimize shipping costs.  Sturdiness of parts as well as size and weight may impact how parts can be combined, but I will try to get the costs as low as practical for you.

To insure success when installing this pan gasket

        A. Clean ALL of old gasket material off.
        B. Peen the bolt holes
              i.   Put the peen end of a ball peen hammer into a bolt hole on the case side of the pan rail.
              ii.  Pound on the hammer face with a BRASS hammer until SLIGHTLY domed away from the case side of the pan rail.
              iii. Repeat for each bolt hole.
        C.  Install dry (cork composite; NEVER rubber) gasket with NO added adhesives.
        D.  Install all bolts to finger tight.
        E.  Tighten each bolt until the gasket just STARTS to show VERY SLIGHT deflection out from pan.
        F.  Make sure you tighten bolts in an alternating side pattern.
        G. Tightening beyond this point only splits the gasket and promotes leaks.

Procedure to replace manual shaft and/or kick down seal(s)

Valve body AND the shift linkage must be removed to replace the manual shaft seal and/or kick done seal(s).

To make that easier follow these steps:

1. After removing the pan, remove the two curved tubes that are in your way.

2. Remove the four 7/16" head bolts that hold the valve body together.  (Do NOT remove the three 7/16" head bolts that hold the valve body to the case yet.)

3. Remove the four screws that hold the valve body together.

4. CAREFULLY slide the valve body section that is now loose off of the two straight tubes.  (Make sure that you slide the metal spacer plate along with it.  Be VERY careful to not lose the checkball that is sometimes inside this valve body section.)

5. Now you can take out the three bolts that hold the valve body to the case and the valve body will come out.

6. You will need to remove the 1/2" nut on the end of the kick-down lever, but make sure you hold the kick-down arm when you do this instead of torquing against inner lever. It breaks off VERY easily.

7. Remove the nut on the end of the manual lever (inside the case). When you do that, be very careful. There is a spring loaded detent in the case. DO NOT let it shoot out.

8. Pry the old manual seal out of the case.

9. Install the new one by using a hammer and an appropriate sized socket as a driver.

10. With a small screw driver, pry the kick-down seal out of the manual arm.

11. Install new kick-down seal.

12.Reverse procedure to reassemble. Make sure the detent is riding on the detent notches.

13. Make sure the manual valve is engaged into the manual lever and that the kick-down lever arm (inside the case) is between the stop and the kick-down valve.

14. Install the three 7/16" head bolts that hold the valve body to the case and torque them to 65 inch-pounds.

15. After sliding the valve body section back onto the two tubes, make sure you start all four screws and all four bolts BEFORE you tighten any of the eight.

16. Tighten the screws snuggly and the 7/16" head bolts to 65 inch-pounds.

17. When you are done, verify the operation of the manual lever and the kick-down lever. You should feel the detents when you move the manual lever AND you should feel the spring pressure when the kick-down lever pushes the kick-down valve.

It is not as complicated as all of this sounds and using this method, you don't need to remove the servos.
