Help with leaky 350 turbo trans!! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I recently put a new crate engine and rebuilt trans in my 72 jimmy, the problem is the trans will not stop leaking. First my trans pan wouldnt stop leaking so i threw an aluminum one on and that stopped it, and now it looks like either the detent cable or dipstick tube are leaking (both are new). I was just wondering if anyone else has had these problems, a small drip wouldnt bother me much but this thing is like a constant drip. Both the detent and dipstick look like they are fully seated but I cant figure this out, any advice would be helpful.

Take it back out and sand the chrome off the part that goes in the trans. Then when you go to put it back in, add some sealer to the "O" ring and let it set up overnight. Should take care of it.

I have had good results coating the tube end and O-ring with RTV silicone. Coat it, put it in, and let it dry over night. Sanding the chrome off sounds like a good thing to do.
