I have a problem with my Turbo 350 trans. where transmission fluid leaks out quite a bit after it has been sitting for a while during storage. Is this the seals getting dried out and leaking? Is this a common problem on these transmissions? It does not happen when I drive the vehicle on a consistant basis. Has anyone else experienced this problem?
MIne too... I thought that problem was only on the nailhead style 400's. I geuss that I was wrong. :gt:
Carl, It happened to me also on my turbo350 trans, one year the car sat for about 3 months and there was tranny fluid all over the garage floor. This does not happen all summer when the car is being used. Only happened once, the following year it sat also for about 3 months and I only had a couple of drops. o No: Your guess is as good as mine
Sorry for posting this one! After further checking on the boards I found that this indeed is what happens after a trans. sits for a while. Guess I need to start the car more often so that this doesn't happen. Thanks.
Re: The easy fix ??? Can't do that this time of year... :ball: my TH350 also leaked while stored last winter. It continued into the summer, so I checked and found the speedo cable knurled nut was not tight anymore. Tightened it up, and no more leaks all summer. We'll see how it is this winter...
Tranmission Leaks, well, they tell me that when they sit, no matter, dynaflow, st300, 400s, the torque convertor fills up and then the gravity takes over, and the TC lets loose and on the garage floor it goes or driveway. If you drive the car the seal stays round and seals, when they sit for a while the seal leaks, you can change the seal and not much will change other than it may not leak as quickly. Also appears, is if the car sits on a decline, it may enhance the leaking, been there, still there, run the monster and it's never as bad has having it sit there and leak on the driveway! RV
Roberta, Thanks for your info. My 73 Centurion started leaking trans fluid when it sat for about two weeks while I tried to get around to replacing the starter. The car shifts perfectly. I took it to a couple of transmission shops that told me it needed to be rebuilt because it was leaking near the front pump. My driveway is on a nearly 45 degree angle. You folks may have saved me about $400.00 :beer I owe you a cold one.
What I have found happens too is that the convertor will drain into the pan when the car sits for an extended period. If you check the stick, the fluid is way overfilled. If the seal on the dipstick tube is marginal, then fluid will leak from there and sometimes give the appearance of a leaky front seal. This happens with the speedo cable seal as well when the fluid reaches a level to seep out of there. You can try the stop leak and see what happens. Just put some cardboard under the car to catch the fluid and check the level before driving it in the spring.. Just my 2 cents, Mark
My father and myself have our cars in the same shop. If I go in there right now, I have to put on ice skates to slide through the Fluid!!!!!!!!!! My carboard floated out the front door!!
