I have a rebuilt 70 Chevelle 400 turbo, new GM Corvette 1800 stall converter, B&M clutches, shift kit. If I drive the car it doesn't leak or use the B&M trick shift fluid, when I park the car it doesn't leak fluid for five days. On the fifth or sixth day it leaks about a Quart of expensive fluid on the gsarage floor! What the hell causes this? Mike[/LIST][/LIST]

It sounds as though the torque convertor is leaking down over time. Have you jacked it up to see where exactly the overflow is coming from? You may have something as simple as a fill tube seal gone bad.

I replaced the filler tube o ring , but I can't seem to tell where it's leaking from it drips off of the deepened tranny pan. will I have to replace the converter, its only got 1k since I rebuilt the trans!

No auto trans expert, but I remember Powerglides doing this quite a bit. I think it may be an over full condition. The seal on the coverter may be going bad on you and when air gets in the converter it burps out the excess fluid. The dipsick you have may be incorrect and the excess is comming out the breather vent in the top of the trans or the govenor cover.

Does it shift fine with the lower level of fluid?

I wouldn't worry about the Torque Converter of or the Front Seal. After several days, most of the fluid will drain back into the pan. Most of the elements in the trans will eventually drain back into the pan when not in use. This is why you check ATF level while the engine is running. I would check the dipstick tube as previously mentioned. ATF can travel far so the drip might not be the leak!

Check the speedometer cable. I had a leak behind the theads of the speedometer cable input on the tranny. The whole thread assembly was loose and leaking. It took me a wile to figure it out. Check that out, it could be a possibility.

hey is it leaking were the converter goes into the pump
if it is the bushing could be worn or damaged an after a couple of days the seal is just worn out an then the fluid starts to leak out
i have seen this on rebuilt trans before cause of a manufacture error
either replace bushing or take trans back to place of purchase

An aid in chasing down a leak........ the spray cans of foot powder.

clean the tranny, spray some of the powder on.

After the fluid hits the floor check where it has run across the powder.
