Adding a drain plug 727

AND NOW ANOTHER ANNOYING STORY from the old days

When I was stationed at NAS Miramar in the early 70's our shop was located WAY out towards the W end of the runways. We had permission to do work on our cars "when off duty."

One afternoon I was out doing something and our "less mechanical" Chief (CPO) came out to change oil in his 67 Chev. Asked me "how."

I said "you know how to get it jacked up safely"

"Yes." (we had a big ol' floor jack)

"Well" I said "Get it up, go look for a drain plug on the engine and pull it out and let all the oil fall out."

I don't remember if he was changing the filter. likely not

So some time later, he comes over, says "It starts and run but now IT WON'T MOVE"

Of course!!!! Some trans shop HAD INSTALLED A DRAIN in the transmission and YOU KNOW WHAT THAT MEANT!!!

Not only had he drained some of the transmission, but had poured 4 or 5 quarts of new engine oil in on top of the old oil still in the engine!!!
