Question about 1989 Lincoln Mark VII

1 Answer

1989 lincoln mark vll automatic transmission

Transmission won't shift into overdrive. Problem started when I manually shifted from overdrive to drive in pass manuever on an interstate hwy. I was doing appx 55-65 mph when I downshifted, and shifted back to OD the transmission slipped and engine rpm flared. Ever since that day, I drive with shifter in Drive position because in the OD position the transmission slips when it shifts into OD ( at appx 45 mph @ low throttle ). Trans has no other symtoms or issues and fluid level ok. Is this a common problem with Ford transmissions? Any feedback would be appreciated, thank you

It wont shift into overdrive the transmission has pressure I changed to fluids when I go to pass it wont shift into overdrive


strange as it may sound, transmissions do not shift into overdrive to pass
they down shift a ratio to get extra torque from the motor and will stay down shifted until the vacuum actuator shifts it back and only then when the VSS reports to the TCM that a ratio change up is needed will the overdrive click in
If you cannot get OD under any circumstances run the fault codes and check for a problem overdrive servo/ solenoid , TCM unit

2004 Ford Sportrac having problems with trans OD flashing on and off and sticking in gear?


When the Torque Converter Clutch (TCC) isn't engaging or locks in engagement the light flashes a warning...The TCC solenoid may stick due to dirty transmission fluid...If the Check Engine Light
(CEL) is not lit have your transmission fluid changed...If it is lit the code is probably pointing at a defective TCC, Computer (PCM) or the clutch itself... you can take the vehicle to an auto parts store and have them read and define the trouble code for free...saailer

Tranmission will not shift into next gear from


Try changing the transmission fluid and transmission fluid filter. It is a fairly easy but kind of messy job. Just buy the new fluid and filter, Grab your metric socket set and go at it. NEVER WORK UNDERNEATH A HOT VEHICLE. You have to pull the transmission pan to do this job. When you break the gasket seal several quarts (liters) of transmission fluid will cascade down on you. Be ready for it. Don't forget that when it stops draining there is still a lot of fluid left in the pan. When you finish cleaning up the fluid clean the gunk out of the pan. Install the new filter and reinstall the pan with a new gasket. Do not over torque the pan or filter bolts. If you strip them out or break them off you will need professional help to repair it. Refill the transmission with fluid. It should take six or seven liters.

98 Grand Cherokee Transmission problem: At hwy speed transmission surges or shifts down RPM'S jump 200 to 300 RPM. Only does it when Transmission is fully warmed up.


check oil level first, than check the electrical connector on the tranny. This sound like the transmission shifts from overdrive to drive. Check the wiring from the transmission to ECU and other items. If than happen again, check the shift cable, kick down cable. If that doesn't help, let the tranny be checked at a servicestation.
