  • 1998 FORD TAURUS
I have a 1998 Ford Taurus, 3.0L, Automatic with 134,000 miles with multiple codes(P0743, P0750, P0755, P0760).
The engine runs out fine and idles as it should but when it is cold and you put it into drive or reverse it will kill the engine immediately unless you keep up the revs up 1500-2000rpm. Also, when accelerating, it makes that "pinging" sound ie: pre-detonation, like the vehicle is under a load.
When the car is at normal operating temperature and your driving at a steady 60-70mph, every 5 miles or so, it will start to lose power and will not keep the rpms up, just like if you were steadily braking and giving it gas at the same time. If you pull over and turn the key off and restart the car it seems to reset this condition for another 5 miles.

Any ideas or help would be greatly appreciated.

Hey there

the codes you listed are all transmission related, the 753 is a slip code for 3rd gear. The fluid is probably burned if you check. And what may be happening is the converter is locking up causing all of your problems, the transmission will need to be gone through sorry for the bad news but good luck with the repair and check the dealers reman against a rebuild there is a great warranty on the units

Thanks for the response. I've been a tech for more than 20 years but unfortunately (LOL) not on the tranny side.
As you described, I also thought that the problem involved the torque converter but not being knowledgeable in this area, I was thinking, and hoping, more on the electrical side instead of internal problems, because of the P0743-Torque Converter Clutch Solenoid Electrical, P0750, P0755, P0760-Shift Solenoid A, B, C Malfunctions respectively.
I purchased this vehicle from the original owner "as-is"" with the existing problem. The fluid still looks good and the owner stated that no service(trans flush) or addition of any new fluid since it was new.

Does the above codes and further info, lead any body to think differently, or am I just hoping on a wish and a prayer for a cheap fix to turn this one.

Thanks in advance for any thoughts.
