Re: Pulled engine/tranny - Found no fluid in tranny at all!

Hi Chris,
Just to answer your freewheel question- a couple of things to look for:
- Excessive wear on the freewheel hub teeth and the freewheel dog teeth.
- Wear on the inner surface of the freewheel hub- its supposed to be smooth but can have grooves worn in it.
- Gunk and all sorts of metal filings stuck in the inner part of the smooth freewheel hub surface. If that's the only problem, it can be cleaned out.
Are you planning to disassemble the freewheel to inspect it? If it's the older 6 roller version, it's very easy to put it back together with an elastic band. If it's the twelve roller version, with two little springs per roller, then it's nearly impossible to reassemble it without the special Saab freewheel tool. I've tried and failed, and I'm a pretty patient person. You can count the number of rollers by looking into the freewheel.
As to your other questions, you will get the gears to spin when in neutral and turning the input shaft. When I open a transmission for inspection, I pull the top cover and make sure I can slide the selectors into each gear. I usually have the bell housing off, and I try to operate the trans in all 4 gears by rotating the ring gear. Unless something is terrible wrong, I can always make it rotate. Easier in some gears than others. In freewheel, it "freewheels" in one direction and drives in the other. With freewheel locked out, it drives in both directions. After that, I pull the rear cover (keep track of the thin metal shims behind two of the three shafts!) and check the tightness of the shaft nuts. Of the 10 transmissions I've taken apart in the last year, 8 had loose nuts and 2 had the nuts WELDED to the shafts...
I was given yet another VSaab transmission last weekend by a kind soul. I first popped out a driver to drain the oil and out came a cup of water, then same nasty oil. Not good. I then took off the top cover and found serious rust on the top of the gears. I didn't go any further with this one. Too bad...another VSaab transmission for the scrap pile.
