Donor Disassembly

Now the disassembly of the donor trans starts. Obviously it had been in sitting outside in wet grass for some time for the bottom of the pan to look the way it does. But it had a rag poked in the dipstick hole, and I was hoping that kept the majority of the water out of it. Pulled the man, and did find some water in it. Not much but it had water in it, and I knew it was from sitting and the water had not been run thre the trans. Looked very nice and clean inside. Pulled the valve body, nothing in there but pretty nice colored fluid. Awesome !!!

I'm enjoying this write up so far. Least its not one those heavy cast iron transmissions that your rebuilding.

Time to pull the front pump. Notice my homemade tools. I have used these forever and never ever had to use a pair of slide hammers yet. These made with a scrap piece of all thread I picked up at work, some wide shouldered jamb nuts, and I forget where I got those knobs, but you can also use more nuts and big washers which do the same thing, then use a pry bar off the bell housing.

Ahhhhhhhh, Looking very nice inside. Very Clean !!! Lovin It !!!

Very Clean. Obviously a little moisture or condesation did get in the trans by the looks of this drum. The rust pars wiped right off like dust. No Harm whatsoever.

And this one come apart just like it was supposed to. Simply held the input shaft and pulled the assembly out in one unit. Still looking nice and clean. Notice the Band is still in the case and its original location.
And moment I been waiting for. Hoping the direct drum is the smooth race type I bought this transmssion for. This one sure looks a bit differant than the other one. The sprag gear is pefect and nice sharp edges also very clean !!!

Showing a little sign of some wear finally. So yes, its a used trans, but still impecable condition. You can see darkness on the steel here. But its also possible that was left from the previous rebuild too. The discoloration is harmless in most cases as long as its not glazed and shiney, which sandpaper, or replacing the steel fixes that issue.

Got any special tricks to installing the direct piston in the drum, besides using 2-3 c-clamps and alot of cursing?

Sure do. I suppose you are talking about getting the piston down in the drum without tearing up the lip seals??? You sure don't use c clamps to force it. That will tear the seals then the piston won't compress clutches. I have a little tool, that I found by accident one time at a paint supply store in he hobby paints area. You are supposed to use a tool made with wire end on it, but I have never used one. In the beggining I used feeler guages. You want something thin and flexible with out sharp edges to not tear the seals. Its industry standard to use what they call lip seal tool, Its junk in my opinon. Here is a pic of it, and the tool that I use. You use plenty of trans jel or vaseline on the seals. Then use this tool to be pushing the lip seal into position while walking it around the piston to get it fall into the drum. It does take some patience without doubt.
