if i drive it at least once a month all is well,let it sit longer and quite amount of fluid on the floor.1/2 quart.ideas? dont see how it could be the pan gasket,dipstick o ring or shift lever seal.throw some ideas at me
rear seal/front seal or a trans line or the speedo drive gear cover.... there arent many places left
yea i hear ya,but only after it sits for longer than a month?thats whats got me
i dont know why i even asked, i already know i got to get it on stands,wipe everything down,and go from there.sorry
I had the same problem, Mine was leaking from where the speedometer cable went into the transmission. Easy to fix, just two small rubber seals.

i had this question in transmissions class hehe........the amount of ATF in the case AND torque converter is more than the case itself can hold........from the minute you shut off the engine fluid is leaking back from the torque converter back into the main case .....under normal usage this is a very smalll amount thats unnoticed bcoz the second you start the engine it goes rushing back into the the torque converter ........if its parked for extended time the fluid that leaks back into the main case, over fills the main case and leaks out through the vent..........thats why cars parked for years always have puddles underneath them .....then when you start it ...all the fluid goes rushing into the torque converter depriveing the main case ....making it not engage and ppl usually say "oh no the trans is bad" when most of the time if you top it off with fluid it will run fine even after many years........im betting if you track where its coming from .....its coming from the vent........and a possible solution to this is if your going to store it for extended time get a pan that has a drain plug and drain the main case when it goes into storage ....just dont forget to refill it.
I must be lucky some of my cars sit for a month some 4 months over winter , have never had this problem . Will know what to do if I see a puddle of ATF under the car from now on though .i had this question in transmissions class hehe........the amount of ATF in the case AND torque converter is more than the case itself can hold........from the minute you shut off the engine fluid is leaking back from the torque converter back into the main case .....under normal usage this is a very smalll amount thats unnoticed bcoz the second you start the engine it goes rushing back into the the torque converter ........if its parked for extended time the fluid that leaks back into the main case, over fills the main case and leaks out through the vent..........thats why cars parked for years always have puddles underneath them .....then when you start it ...all the fluid goes rushing into the torque converter depriveing the main case ....making it not engage and ppl usually say "oh no the trans is bad" when most of the time if you top it off with fluid it will run fine even after many years........im betting if you track where its coming from .....its coming from the vent........and a possible solution to this is if your going to store it for extended time get a pan that has a drain plug and drain the main case when it goes into storage ....just dont forget to refill it.
So can anything be done to prevent this , lets say if the car will be sitting for 3-4 months ? Would draining fluid from the cooler lines help ? I've never had this happen , but would like to prevent if possible . Any suggestions ?
Another question , is this just a 727 problem , or all automatic transmissions ?
Thanks
Okay , that makes sense . I 40 years of mopar products have never had that problem , ols seals , yeah that will do it .Really no need as long as all the seals in your trans are in good shape.
It usually occurs with older/high milage transmissions as the seals-gaskets and Orings become hard,dried out and shrunk. How to prevent it....... Have the leaking areas PROPERLY repaired and you should be able to store your ride without leaks. Don't be fooled into hearing thats just the way they are, they all leak. Usually either a seal surface is worn or the tech misdiagnosed it. If you have multiple leaks you might consider removing the transmission for a COMPLETE reseal. Oh... and stay far away from offshore seals !!
