Question about 1990 Lincoln Town Car

1 Answer

No overdrive My 1990 lincoln town car does not shift into overdrive but it doesn't slip in any other gear nor does it hit hard into any gear either. If I get on the gas it will go into overdrive. Can anyone tell me what might be wrong and possibly have a solution to the problem? Thanks in advance. Joe.

Hi Joe, what you need to do is go to a trans. shop and have them adjust the TV (Throttle Valve) cable. You can do this yourself but you need a really low PSI guage. When the line pressure is at 0 - 5 PSI, it will be adjusted properly. Usually only trans. shops will have the proper tools to do this. It's very important that the TV cable is adjusted right on the money or you'll smoke your transmission.

I hav ea 94 lincoln. It works in reverse. I start out in drive. It is fine from 1st to second gear. It will not go into third or overdrive.


This is a computer shifted transmission, if there is a problem with the electrical shift solenoids the system will set a code. Aamco does this code testing from free, I suggest you have them hook it up and see what shows up in the computers memory.

Transmission over drive is causing the transmission to slip. When I take off the overdrive the transmission functions normally but it uses much more gas.


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.

1994 shift only when overdrive is off.


first thing to check is transmission oil level and quality. If that is fine than your looking at either a valve body problem (valve body is what controls the selection of gears) or possibly a problem with the bands on the planetary gear set, they can be tightened in certain models. However i dont think it is the bands.
Does the overdrive only engage 4th gear? or does it feel like the gear ratios are different between overdrive and normal before the problem happened? some overdrive buttons engage final gear and some do as much as change gear ratios like in a cvt (contantly variable transmission) and some just change the timing in the gear changes to provide more rpm/power.
My best guess is that the valve controlling the overdrive in the valve body has failed and therefor you dont get a response from the transmission (i.e no gear shifting when overdrive is selected)

My 1990 Town Car auto tranny slips in overdrive


There are both bands and clutches in your transmission and likely you have an internal pressure loss that is affecting overdrive. Repair cost i can't give you but being as old as it is likely you can get an identical vehicle for what it will cost to repair. You may be able to prolong the inevitable by using a conditioner such as lucas,(only one I've seen that actually does help in some cases) but it can't fix what is worn, so even if it works better, it will only be temporary. I know that isn't exactly what you wanted to hear but that's the way it is.
