What causes 2000 Lincoln contineal check transmission light to come on?

Change the solenoid pressure control pack
inside the trans pan

Roger, that doesn't even make a whole lot of sense to me. If the overdrive is causing the transmission to slip, wouldn't it also cause the fuel mileage to go down? Are you sure the transmission is slipping? Or is the transmission simply shifting in and out of overdrive? If it is, is it shifting at the proper speeds? Driving at around 40 - 50 Mph will sometimes make the transmission go in and out of overdrive repeatedly. This can be perfectly normal.

Have you checked your transmission fluid level?

Is your overdrive off light flashing? If the transmission is actually slipping the OD OFF light should be blinking at you to let you know there is a transmission problem. Either that, or the Check Engine light will be coming on. In either of these cases, you need to scan your onboard computer network for possible fault codes.

Inspection is required.

Is you cigarette lighter working now. Odds are it is still not and the fuse he changed belonged to the Transmission ecm. The car will still run, just in a modified or "limp" mode.

HAVE VECHICLE SCANNED SOUND LIKE TORQUE PROBLEMS. OR VECHICLE SPEED SENSOR. CHECK TRANSMISSION FLUID LEVEL.I WOULD DO A TRANSMISSION FLUID AND FILTER CHANGE FIRST IT NOT BEEN CHANGED A LONG LONG TIME. BEFORE GETTING DEEPER INTO MAJOR TRANSMISSION REPAIR.ANOTHER THING MAKE SURE ENGINE WELL FINE TUNED IF NOT IT WILL CAUSE TRANSMISSION SHIFT PROBLEMS. LIKE I WAS SAYING IF TRANSMISSION FILTER STOPPED UP IT CAUSE LOW TRANSMISSION FLUID PRESSURE CAUSING LOTS TRANSMISSION SHIFTING PROBLEMS

have the tranny shift solenoids checked out.

are these codes shift solenoid codes because they could be.

It could be a couple of issues:

1. Since you mention 30mph a speed when the transmission wouild normally shift into 3rd, and again at high speed (you didnt' mention MPH) where it would possibly shift again, it's possible that the transmission is slipping. Check the fluid or better yet, if it's got around 50-60K on it, have the fluid and filter changed.
2. Another cause could very well be fuel related, be it a filter, fuel sending unit, or the pump itself

I'd start with the transmission fluid. Check it and if the color is starting to brown, or gives a slight burning smell, have it changed along with the filter. If it's just low, then that definitely would cause the transmission to slip.
Best of luck and post back with any other concerns.

Check the level of the transmission fluid, low fluid can prevent the transmission from shifting.
