Ross will have more detailed advice, but years back I replaced both seals w/o removing the pan. Carefully drilled the seal with 2 small holes, inserted self-tapping screws and used them to pry the old seal out. On a different occasion I found the recess deep enough to accommodate 2 seals so I just added one on top of the existing seal.
Thanks Dave. If I didn't already have the pan off for cleaning, the seal removal with the shaft in place would be tempting. Since I have gone this far I think I'm going to try and remove the shafts if for no other reason than to check them out for burrs or rough spots that could abrade the new seals.
JD, I purchased the pan gasket and shaft seals from Ultramatic Dynamics last year and chose to replace the seals without removing the shafts. Yes, it is tight working conditions and I had to fabricate a couple of adaptors to "press" the seals into the seal bores but it worked out perfectly. Basically I did what OD suggested and punched a hole into the old seals and inserted a small sheetmetal type screw into the hole. If you choose this method, use a screw that's softer than the shaft just in case the screw threads come in contact with it, even brass will work for this application. If I recall correctly, there was a hole in the frame on both sides that was almost directly in line with the shafts. I used these holes to insert the screwdriver and access the screw heads. Once I had the screws installed, I simply pryed the old seals out with a pair of needle nose vice grips being careful to use a thin piece of wood between the grips and the tranny case. Both seals came out with little effort. The adaptors I mentioned were basically bushings that were smaller in diameter than the seal bores and had center holes large enough to fit over the shafts. I cut the bushings to suitable lengths that would allow me to insert a tool similar to a brake adjusting spoon or nail remover between the frame and bushing and then "pressed" the seals into place by prying against the frame until the seals bottomed out in the bores. If you're capable of working in close quarters, then this is a relatively simple approach to replacing the seals without removing the shafts. Unless the tranny was on the bench, I wouldn't worry to much about removing the shafts for deburring as you probabaly run more risk of causing damage by removing them in the car than if you left them in. In addition, I may be mistaken and Ross can confirm this but I believe the shifter shaft has to slide "outward" for removal. If so then the X frame restricts the tranny from dropping down far enough for the shaft to slide out.
