I have a 2003 Ford Escape V6 2WD, it has 64000 miles on it.
Recently when driving uphill my car downshifted and o/d light came on blinking then when i turned the car off and turned it back on o/d light seemed normaln, but after a white it came on again but this time with the Check Engine Light when i checked what was the problem i had P1744.
I noticed that blinking o/d light comes on only if im driving over 40mph for a period of time usualy 10-20 min. if i stay under 40mph everything seems ok.
Also when blinking o/d light comes on car seems to shift more drasticly, what i mean is gear changes aren't smooth like normal.
Is it a mechanical or electrical problem? And if any what is the best sollution?
Here is what seems to be a good explaination of the problem as it deals
with "FORD: 1996-98 TAURUS, LINCOLN-MERCURY: 1996-98 CONTINENTAL, SABLE "
This should also relate to yours except for the exact resistance of the TCC.
