Hey guys, I have a significant leak my transmission on a 2000GTP. I've managed to follow it to the feed line on both ends. One end is the fitting into the transmission. The other end is attached to a rubber hose with a clamp. I tried to upload a pic but couldn't so here is the link to the picture. http://img145.imageshack.us/img145/2635/81970621.png The clamp came from a transmission cooler i had installed a couple years back. The installers cut the main line to the radiator and spliced the trans lines into the auxiliary cooler. Not sure if this is the best way to do it, but oh well...can't go back now.
A little background.
Third transmission (car has 224K).
When the last transmission was installed, I think the feed line fitting was stripped a little because I had a small leak after install. A few nights ago I was doing a tranny drain and refill and decided to pull the fitting and teflon it to see if that would help. While reiinstalling the line into the transmission, I though I had striped the bolt out. Did some research and figured a HeliCoil would be the best repair, but when I tried to remove the fitting to the threads right, I tested the fitting again and attempted to spin it a little bit more in order to assist with drilling the hole. Well, after about 3/4 of a turn the fitting snugged up and didn't leak for two days.
Now the fitting is leaking again, it's not as bad but it's still bad enough to to concern me with driving it.
I have a few questions:
1) what thread are the fittings? I found a resource on here via Trannyman saying that the thread count was (3/8th 18) but when I called around about HeliCoils and looked online, all I found was 3/8 16...so I guess i am just looking for confirmation I am looking for the correct thread count.
2) has anyone repaired this hole with a HeliCoil, if so, could you give me some pointers
3) Does anyone know of a better/different/less invasive way to repair the hole? I am concerned about getting shavings inside the transmission.
4) Is it possible that the fitting is bad and not the tranny housing? It looks like a lot of fluid is coming out there.
5)what are these types of fittings called?
I'm not a complete newb in terms of working on this car, however transmissions are a world I haven't really worked with...and neither are helicoils (I always tapped the whole and went up a size bigger but you can't really do that with these fittings I don't believe.)
Thanks in advance to any help.
