I saw a tiny leak at the wiring where it exits the pump motor. I know there is another O-ring on the pump that the reservoir retainer bolt passes through. It seals the motor from the ATF in the pump. I found a great YouTube video where the guy took it all apart and cleaned the motor up. Power top motor overhaul Since the problematic O-ring is included in the overhaul kit I figured I would take it all apart for cleaning. When I opened it up there was some ATF inside the motor so I had to soak it all in solvent. The armature was pretty dirty so that needed polishing. The hardest part was fabricating retainers to hold the brushes out of the way while you dropped the armature back in. The video shows how to do it. Be sure to scribe lines so the parts go back together properly. The kit includes new pump balls so those get replaced too. After the pump is back on the motor the O-ring is placed on the pump shaft. Be sure to gently force it down into the groove it sits in. That way the pump gears will not chew it up. I tested it and it worked much quieter than before. No leaks. I returned the cylinders to the car and ran the pump in a container just in case it leaked. I watched as the top went up and down as it should. No leaks and the motor sounded better than before so cleaning it was worth it. Then I heard a loud SQUISH. The pass side cylinder was gushing ATF. WTF?!? Upon inspection it looks like the hose fitting at the top blew off. The threads are stripped out and the fitting came loose. I was careful not to over-tighten the fittings. I guess these guys were just too old and I will be buying new cylinders after all.
