Default HELP!! Draining Torque Convertor (trying to anyways)

How do I do it? On my Crown Vic it has a drain plug in the TC and you just turn the engine until the drain plug is down then open it and walk away for a couple hours. Come back and there's another 7 quarts in the bucket.

WHERE IS IT ON THE 'VETTE?!?! '77 350/350. I turned the TC and turned the TC and turned the TC but there's no plug. :cry I know I went all the way around because I saw my fingerprints from before I started turning.

How the hell do I drain this thing? :confused:

Thanks for the help,

Colin.

ps. yes, it is 12:24 in the morning, and it's dark outside but I can't sleep, it needs to be done, and I want to do it. :crazy: :jester

"WHERE IS IT ON THE 'VETTE?!?!"

Nowhere. The General never installed drain plugs on the converters, though it is not uncommon to find one where some enterprising past owner has installed one.

"How the hell do I drain this thing? :confused:"

In stock form, you can't. I assume you are just changing the ATF? If so, standard practice has always been to drop the pan to allow as much ATF to drain as possible. Replace the pan and then top off the tranny to the correct level. Yes, I know you don't get all of the old fluid out . . . that is just the way it is.

With the convertor still in the car its impossible to get all the fluid out. The best way to get the most of it out is to pull the tranny line that leads back to the pan. This would be the return line. Hold the open line into a bucket as you have a friend start the motor. The trans will pump will pump maybe half of the fluid from the convertor before the line starts blowing air. Shut the motor down the moment you see the air blasts. Then proceed with dropping the pan.

When I first got my 79, I took it to midas. They have a bendex cleaner that purges all the fluid out washes the inside of the tranny and then you drop the pan and look at the filter. I couldn't believe the shi#! that was in there. Had them do the motor as well. I think it can only help, as just draining the fluid and changing it does nothing to clean the sludge and grime that builds up over time. Now if my front seal and rear seal would stop leaking I could say that the car has no leaks and the garage floor is happy. Will address the seal thing with a bottle of trans seal and drive! Later, ZMAN :cheers:

To be honest with you, if your tranny has never overheated and the level is always kept full, the fluid can go a long long time before needing changing. Even the life expetancy of the tranny. The sludge is usually a normal bi-product of tranny life and does not nessisarly hasten the transmissions demise.
