    Please fill out the following to ask a question.

    MAKE: Cougar
    MODEL: Mercury
    YEAR: 2002
    MILES: 115,934
    ENGINE: 2.5 l standard
    DESCRIBE ISSUE....So I pulled my Cd4e apart, I have both Rotundra OTC tool kits, the t94's. My initial problem happens when my car wouldn't shift from 2-3 and then stopped shifting altogether. I could get it to move only in the first 3-4 minutes of running it then no shift. As time went on, it became harder and harder and i had to literally wait just to move it a couple of feet. Fast forward to now....

    Taking it apart i found 2 leaks around the pump, and the case bearing was ripped and needed replaced. i also noticed that the motor mounts on the car? were non existent. the clutches were severely burned up and the hard parts, clutch plates looked like a brake rotor where someone didnt change the breaks and was doing metal on metal..

    I have torn down the CD4E in a shop, I have changed bushing after measuring them, i have depth micrometers, the magnetic snap on end checker for the drum, both t94 kits from otc, the computer used to test the solenoids and the eec breakout box as well as a bushing puller, driver installer set, press...basically the whole nine yards.

    My problem is this. I am on my 2nd drum, the first was used, the second was sworn tested and working rebuild, and the third I ordered brand new. i have replaced ALL the seal in the drum and pump, replaced the pump gears, changed the gasket and even torqued the pump down to the case and attached an air test plate where the valve body goes.



    I am bleeding air both ways from forward and direct clutch, and the reverse is just hemorrhaging air.. I used the seal installers, made sure I used the transtec seal roller and checked this drum and solenoids 5 times.. when I say checked, I mean I removed the solenoids/pistons and verified under a lope that they were not cracked ripped or torn.

    Now is it suppose to bleed air from forward to direct clutches and vice versa? i do get them to engage, but air leaks when they do, and the ATSG and service Manuel says this is bad.. I have filled the case with ATF fluid just in case the seals were not actuating properly.....

    What am i doing wrong here?

    Tried spinning the drum to. I can't pinpoint it.. wait the pump assembly has a check ball in it, could that cause a cross leak?

    I think I found it, the transmission kit sent me 2 gaskets for the pump , one was suppose to be the revised edition. Both were for the old style. I ordered another gasket for the revised pump and will keep y'all updated.
