[DML] Re: Automatic trans leaks

["Harold McElraft" <hmcelraft@xxxxxxx>]

I'd bet it's the shift cable. The internal seal design is awful. As 
soon as you stop the engine the fluid drains down into the trans and 
out the cable. The cable design should have been on an angle with 
the cable going up some. I think because of the seal design, if you 
keep a full trans, the leak cannot be prevented. The cover for the 
cable shrinks and exposes the porous cable housing. If you can stop 
the leak at the front of the cable nearest the trans, the fluid 
travels through the cable and comes out at the other end. I keep 
screwing around with it but I can't seem to stop it. I have toyed 
around with trying to modify the shift cable some - so far Grady's 
fix or something similar seems the most practical but I cannot stop 
the leak. BTW, I did pull the trans and put in a NOS cable with the 
heat shrink fix. It was fine for about a year. Now it is the same as 
it always was.
