I have a 1992 Lincoln Mark VII.Thetransmission works fine until you use
overdrive.Once in overdrive it slips as soon as you get to 45mph.In normal
drive it works fine.I found out it could be a TV Bushing.Where is this
located and is it something that can be done at home?
The bushing is located on the end of the TV cable at the throttle body. Here's
link to a tech article: http://www.lincolnsonline.com/tech/00052.html
If you have driven the car much at all with the cable disconnected, the OD
likely toast. It only takes a few miles.
If you end up shopping for a trans, keep in mind that the Mark VII trans is
unique. AODs used in Lincolns are a bit shorter than the AOD used in other Ford
A Town Car trans will physically fit, but is calibrated differently for smoother
shifts at different RPMs.
Okay.Thanks for the info.I guess it sounds like I may as well leave it the
way it is.I do mainly city driving anyway.Guess the mileage will be a bit
worse if I take it out of town.Thanks again for the help.
hey Tom.I went out to the car and took a pic.it is exactly as the link
showed.This cable is completely disconnected.Is there any chance that
putting this part back on may get it working again or would you say my OD is
completely toast?Will this bother the regular drive?Everything else seems to
work just fine.
The bushing needs to be replaced, leaving it disconnected will trash the rest
trans very quickly. For ~$3 and 5 minutes, you might get lucky and the OD will
DO NOT drive it until you replace the bushing if you have any hope of saving the
Lugnut, all of the Mark VII AODs were controlled via a TV cable. They never
IIRC, ur Mark has the electronic AOD-E trans which does not
use the bushing. It is electronically controlled. If the
trans converter is slipping or shuddering, the first thing
to do is a complete service including changing the filter
and draining the converter to get all the old fluid out.
Refill with Dexron fluid and use either Shudderfix or
Lubegard Red additive in the correct amount for the fluid
installed. If it is a fluid problem, it should clear within
50-100 miles of driving if not immediately. Both the AOD
and the AOD-E also have a weak point in the OD band which
engages around 40MPH in normal acceleration. If it is a
band problem, you are in for a rebuild. If it is a failed
converter, you may as well rebuild because of the R&R labor
expense. If you have a lot of miles on it and service has
been neglected, ur chances of salvaging it are greatly
diminished. The longer u drive it while slipping the closer
u r to complete failure.
