What should the gauge read with the TV cable unhooked on the transmission? I tried that and the pressure was 85psi, I suppose that is too much (= something wrong in transmission). Thank you

If you have pressure at the port with the cable Dis-connected, something is wrong.2003 Town Car Signature - 3.27 RAR, Dual exhaust and J-mod - SOLD 9/2011

Supposedly models that came with TV rods default to full pressure. Don't suppose you just put in a new transmission that was originally in a rod-equipped model?
SFAIK, all cable models default to zero, which is why so many people report killing their AOD by driving with a bad TV-cable grommet on the throttle lever.2012 Mazda5 Touring | Finally working on the LTD again!

Originally posted by Lord Iffy View PostThere is spring in the transmission which shall ensure that after disconnection of the cable the TV pressure will not be zero (that will kill the transmission). When you disconnect the cable under the throtle body (0 TV pressure) it is something else than when you disconnect the cable on the throttle lever (near maximum TV pressure).
are you able to set the pressure to spec with it hooked up? if so i wouldn't worry about what it says when it's not.Give a man a fish and he will be fed for a day. Teach a man to fish and he will promptly forget that he once did not know, and proceed to call anyone who asks, a n00b and flame them on the boards for being stupid.

And it is really not the same when the nylon grommet fails and when the cable at the lever on tranny is disconnected - I have tried it.
Of course it is cable controlled model.sigpic

lets double check the obvious... Make sure you are checking the TV pressure correctly and have the gauge hooked up to the TV port (there is more than one port on the side of the transmission) make sure the TV cable and linkage are installed correctly on the transmission (at both ends). You may want to pull the pan back off and make sure the manual valve and TV valve are seated correctly with the valve body and aligned with the levers in the transmission. also make sure the TV turn spring is installed and working correctly. *NOTE* make sure to check TV pressure with the shifter in the NEUTRAL, never check TV pressure in PARK.
