I do not know what the original seals are made of but I would suggest using some Viton seals when replacing them. Viton rubber has a much higher temperature tolerance and should last longer. They are just two "O" rings, no fancy seals. |

My engine is out for a total rebuilt so access is not a problem. Thanks for the tip.

I often thought about doing just that if I ever have to do it but I agree that the engine would be almost completely disconnected to attempt such a repair. I would bet the axles would have to be taken out. After all that you may as well remove it and do any other repairs that probably would need doing. I believe there will always be some seepage from the shift shaft due to the inherent design of the thing. The Corvair uses a similar but replaceable lip seal on the exterior of the transmission but they still have some seepage even when new. |

You do not have to remove engine!!
But you do have to tilt it enough to get the rod out. Which is 70% of the work in removing the engine...
You have to remove the main motor mount bolts from the rear mounts and loosen the bolts on the front ones. Also you have to remove a fair portion of the exhaust (I forget which pieces) and jack the engine up from the rear, placing the shift rod at about a 20 degree angle for removal. I can't remember if the axles have to be disconnected on one end or not.
Like I said, it's alot of the same work as removing the engine.

Once the two pans are off Mitchell, undo the 13mm head bolt, slide the fork off the shaft and out it comes. Remember the position because there are two reliefs in the shaft for the bolt to pass through meaning two possible positions. |

The engine has to come out to do this. You have to remove the shift coupling inside the transmission to slide the shaft out. There are two O rings captured inside that do the sealing. |

I want to remove the shift rod through the tranny and change the two seals, but can not see how. I am guessing (from the parts book) that I have to remove the oil pan(s), disconnect the rod from the inside of the tranny, and slide it out.
What about the seals?
