I have a question, I can drive the car daily or every several days and never a leak, let it stay parked for a week or so and there will be a small area on the concrete, I was told of this when buying and he said he had changed the pan gasket twice. Any ideas or anyone else had this problem?http://i103.photobucket.com/albums/m158/tlowery643/Comet%20GT/Picturetemp1069.jpg

Nice car!

I will take a guess at your leak. Your torque converter fluid could be draining back into the tranny, raising the level and causing a small leak.

Thanks and what is the fix for this if it is leaking back? I am an electrician so kind of limited on my automotive knowledgehttp://i103.photobucket.com/albums/m158/tlowery643/Comet%20GT/01010901031201040420071005f369d6fd2.jpg.

First you need to locate it... As clean as the rest looks you should be able to see where it is coming from. There are too many places to look so you want to start by looking at the area just above the spot on the ground. Straight above the spot on the ground you may need to follow any trail to the actual point of leak. So look for a leak before you move the car and crawl under to look...

Tom; check the dipstick, and the o-ring that is on it where it goes into the case. Hard to find, and an easy fix. I had the 'leaky C-4 blues' and let it get the best of me. I tossed it and got a T5.

thats a nice lookin car. as for the leak, id wipe everything down around the suspect area. then id go to the dollar store and buy some cheap spray on deoderant. you know the kind that turns all white, and looks ohh so sexy. spray that around the suspect area of the trans(no it wont hurt anything), but it will pinpoint the leak. good luck. :tiphat:

one other place to check is where the shift lever goes into the tranny. those are notorious for leaking. mine used to leak after it sat for a while and the fluid drained back in.

Try to locate the leak, or put a drip pan under the car when it is sitting for a long time.

when i got my 70 mav the guy told me the front pump seal is bad. turned out it was the servo cover on the left side and a pin hole on one of the tranny lines that shoots it right at the rear main. i have slowed the leak just been to cold to fix it right

That my friend is why they invented garages! If you don't have one then check the want ads and see if anyone will rent you one for a month. I have a friend who lived in apartments for years and he used to rent garages all over the city to store his cars in and work on them. He was a devout Chebby man and the only rig he had that ran was an old Ford box van.

Thanks Earl but because Blu said "Sucks when the leak is underneath at this time of the year" I guess PaulS thought I didnt have a garage, I appreciate the offer though and going to check it out soon as I get time, been busy setting up my wifes D56 Christmas villages all over the house, but look forward to meeting you on the 15th at the breakfast or feel free to drop by anytime.

I take it you do have a garage and just haven't found the time to pull it in.

No it is the Garage just havent had time to get under and look at the leak, just knew I had replaced pan gasket and that didnt fix the problem.

Oh, OK. Here are some places to look for the leaks.
Look at the kick-down lever and the manual lever. Look at the dipstick - that o-ring NEVER gets replaced.
The pan gasket can also be leaking - gaskets leak unless they have perfect surfaces holding them in place. We don't have many of those so I use a thin film of loc-tite "Gasket Maker" on both sides of the gasket and then finger tighten the bolts. After waiting for 20-30 minutes you can tighten them to specs. That .010" film will even seal a cork gasket and it doesn't slip around like silicone does. It is easy to clean up when you have to replace it too. You can use the Gasket Maker on the orings as long as the parts don't turn. The dipstick is OK, but don't use it on the kick-down shaft.
