Time capsule 727

I am not even sure what I should do about a particular 727.

So I have a 66 polara and it was taken off the road in 1996 due to the transmission going out.

So in 1997 they rebuilt a transmission for the car. I have the receipt and it shows summer of 1997 by the top transmission shop in town. (Still in business)

They placed the rebuilt transmission in the trunk of the car. Probably assuming the swap would happen soon from then. There has never been ATF in it other than to assemble. They also put a brand new torque converter in the trunk, never used and still in the original box.

So time gets away from everyone and here we are, 8/ 2019, 22 years later and the transmission is still in the trunk like a time capsule.

What should I do with it, is it ready to install and run ?

Rani I would drop the pan and see if it is still not rusted change the front and rear seals and pressure check it and see what happens!

Still good if the convertor snout is not rusted. I would put it in and fill the fluid let it idle while filling fluid then shut it down without putting it in gear. Then recheck level in 24 hours and run it through the gears. The reason I would do this is to saturate the clutches and let them soak before using it.

Remove the pan and check for debris and moisture. Push in on the kd valve and see if it sticks. If it sticks, then you have more sticking valves and it all need so come apart; including the governor. If it doesn't stick, clean out the pan and replace the front and rear seals because they probably dried up. 400 grit sandpaper on the converter snout if it's rusty. Same with the driveshaft yoke. Put a quart in the converter before installing. Put four quarts in the pan and start it in neutral then immediately add four more. Don't move the shift lever until you know it's full. You can shut off the motor and check it as long as you don't wait more than a few minutes. Don't wait for it to warm up to get it to the full mark. If you need to drain any out, just remove the neutral safety switch. If your engine is running and you aren't sure your trans is to the full mark---shut it off.

The original transmission in the car (not the rebuilt on e in the trunk) may only need a fluid/filter change and the bands tightened up. It would be worth it to pull the pan for a look. The rebuilt would benefit from few seals.

I say pull the pan and inspect, I bet it will be perfect. Then run it.

I know from experience that trunks are not safe from moisture! I placed a set of freshly ported heads in the trunk of my dart for safe keeping because I was still working on them. And I went to get them back out less than a month later and they had rusted pretty badly from condensation. No my trunk doesnt leak it was purely condensation from the changing temperatures night to day.
