Somebody mentioned in my last thread that I should put a new gasket that goes in between the tranny and transfer case. Never done this before. Any thoughts????

If you are just removing the transmission and transfer case to get at the clutch, you won't have to separate the transfer case from the transmission. The "gasket that goes in between" is misleading. You have to take the transfer case apart to remove it from the transmission. If you don't have any leaks or other problems with your transmission or transfer case, then I wouldn't separate them. If you do have leaks that you want to fix, then you might as well drag the transmission/transfer case out from under your truck and reseal the transfer case. I think the other guy was referring to the shaft seal between the transmission and transfer case (submission 36111B in the drawing). If you find oil is leaking from one into the other, then you may need to replace that seal. If oil is leaking from the transfer up into the transmission there is a oil transfer tube you can purcahse from man-a-fre to put off replacing that seal.

Yeah.....thanks for the input. I have a feeling that it is leaking oil via that seal (3611B). B/c there seams to be oils spatter on my floor pans directly above this. Both out put shafts front and rear seem to do this!!!! I have the tranny/transfer out from under the vehicle right now. So I am figuring now would be a good time to take care of this. Where can I get these seals at. And how hard are they to pull???? Thanks again!!!!
seal 36111B is neither of the transfer case output seals. You can't tell that 36111B is leaking from looking at the outside of the assembly. This seal is literally sandwiched between the transmission and transfer case. The way you know it is leaking is if you start with properly filled transmission and transfer case and after driving some distance, you find that one is overfull and the other is under-full.
The transfer case output shaft seals can be changed without taking the transfer case apart, and they can be changed with the transfer case installed on the truck. 36134A is the front output shaft seal and 36132A is the rear output shaft seal. You can get these seals from Toyota or many of the fine mud-supporting vendors--do a search for transfer case rebuild kits. You will also need new stake nuts for each shaft. It might be easier to replace these seals when the transmission & transfer case are back installed on the truck. This way you can put the truck in gear and use the vehicle to brake the transfer case as you try to remove the nuts that hold the output flanges on. Otherwise, you can make a tool from a piece of flat steel that holds the output flange while loosening and tightening the nut.
If you don't have a Toyota body and chassis manual, you should think about buying one, or you can download an PDF version from the link below. This manual has the procedure how to replace these seals.
