727, sitting 20 years, worries?
A big thanks in advance for any input! I'm starting a project: 62 fury w 318 and 727 push button trans. It has been sitting 20 yrs or so. the previous owner had the engine started and when each of the gears was pushed the trans would engage (car not drivable); it ran fine when abandoned yrs ago. Can I just change the fluid and test on road or is this going to do possible harm (internal parts 'dry out'?). Take it to shop & have them open and check out first? As always, budget is limited & I don't do tranny work. I want to be better safe than sorry! Thanks!

It's probably fine, but I would at least do a basic tune up. Drop the pan, replace the filter and manually operate the gear shift lever looking for binding. Checking the lines to the radiator might be a good idea as well.
After a through break in, you might want to do another "tune up" to get rid of any gunk that was washed out.

Pull the drive shaft and change the rear seal. The yolk probably has rust on the slide from sitting and will ruin the seals lip sooner or later not to mention the seal may have gone a bit hard. If it has sat extensively the front seal is probably the same - seals need the presence of transmission fluid to remain plyable especially at the seal lip. Any rubber or neoprene parts are susseptible to drying and hardening. Make sure to drain the torque convertor by removing the convertor plug mounted behind the dust plate cover when you change the fluid. And lastly, lubricate all cables and shift mechanism with a 30 weight non detergent oil or at the least WD40 or equivalent.
