    Can you possibly post a picture of the location of the leak? That would be beneficial in helping to troubleshoost the problem.

    Re: C4 leaks

    Ron, I may have found the issue.
    i had an after market shifter (B&m hammer) on the transmission and when I took the two bottom bolts off the servo cover to remove the bracket for the shifter cable the seal may have squeeze out.
    i may have pinched it when I retightened the bolts and caused the servo piston pressure to push the atf fluid out thru the pinched seal.
    ill find out this coming weekend hope it’s that easy.

    Re: C4 leaks

    That sounds logical. If you suddenly have a problem that you didn't have before, then go back to the last thing you did on the car, and that usually is the problem. Hope you got that fixed.
