Lincoln Town Car Transmission Recalls
Lincoln Town Car Technical Service Bulletins (TSB)
TSB 10-23-7 – Transmission Cooler Leak
2008 – 2011 Lincoln Town Car
Problem – It’s not uncommon for a transmission fluid leak to develop on the driver’s side transmission cooler tube
Solution – Replace transmission cooler core
TSB 13-4-23 – 4R75E Transmission – Grinding/Slipping/Loss of Reverse
2008 – 2011 Lincoln Town Car
Problem – Some vehicles may experience a grinding/whining noise, unusual vibrations, slipping, and potentially a loss of reverse gear, all resulting from a failure of the planetary gear assembly
Solution – Install planetary upgrade kit and new torque converter
Common Problems with the Lincoln Town Car Transmission
TCC Application in 2nd Gear – 4R75E Transmission / 4R70 Transmission
2005 – 2006 Lincoln Town Car
Problem – A lack of power after the 1-2 shift can be caused by an un-commanded torque converter clutch application / TCC apply. The P0742 and/or P1742 DTCs may also be stored.
Solution – The #7 check ball inside of the valve body may have worn down to an incorrect size, allowing the torque converter clutch to apply after the 1-2 shift. Replacement of this check ball may solve the problem.
Slipping in All Forward Gears – 4R75E Transmission
2005 – 2006 Ford 4R75E Transmission
Problem – Many 2005 – 2006 Ford vehicles equipped with the 4R75E transmission, may experience excessive slipping in all forward gears. Metal shavings may also be present in the transmission fluid.
Solution – Replace forward clutch drum and update ECU with program 06B06

Lincoln Town Car 3rd gear slipping
Although the Lincoln Town Car is a very reliable car, 2001 and later models equipped with the transmission 4R70W/4R70E or 4R75E transmission can have a number of shifting problems. For example, the Lincoln Town Car 3rd gear slip is often accompanied by a lack of engine braking when the transmission is manually shifted into the 2 position.
Cause of most Lincoln Town Car 3rd gear shift problems
The above Lincoln Town Car shifting problems are usually caused by a failed overdrive servo retaining snap ring or a broken overdrive servo ‘E’ clip. If this happens, all of those little broken pieces make their way into the overdrive servo regulator valve, which will prevent the overdrive band from fully applying. If you decide to just have the transmission rebuilt, the overdrive servo regulator valve assembly will have to be removed from the valve body and any damage caused by the debris will need to be repaired. This step is often overlooked by most mechanics and can lead to more transmission problems in the future. However, if you opt for a reman Lincoln Town Car transmission from a company like Street Smart Transmission, you can rest assured that this very important step won’t be overlooked.
How much is it going to cost to fix my 4R70W/4R70E or 4R75E transmission?
Unfortunately, the problem described here will require the removal and disassembly/partial disassembly of your transmission. Given the labor time involved to remove the transmission from the vehicle (this is not a simple task), most repair shops will recommend that you go ahead and rebuild the entire transmission while it’s out. Since they already have to tear it down to replace the 4R70W/4R70E or 4R75E transmission, it sort of makes sense to spend the extra money to do that. After all, you should get a lot more mileage out of your transmission once it’s rebuilt. And since they’ve already got the transmission apart, might as well, right?
Can I drive with a transmission problem?
If your Lincoln Town Car can still make it up and down the road, you might say “It’s fine, I’ll just drive it until I can get it fixed”. But that is not always a good idea, depending on the symptoms. You see, there are a lot of (very expensive) moving parts inside of a transmission, and if something isn’t right, continuing to drive with a transmission problem could damage something else.
How often does a Lincoln Town Car transmission need to be replaced?
The overall lifespan of a Lincoln Town Car transmission largely depends on how well it was maintained. Factory design flaws also factor into this equation, along with how/how hard you drive. But on average, we’ve seen the Lincoln Town Car transmission last for between 130,000-180,000 miles. A high quality replacement transmission however, can last considerably longer if all of the factory design flaws have been addressed and the vehicle has been maintained.
How are Lincoln Town Car transmission issues diagnosed?
It is fairly easy to guesstimate what the root cause of your Lincoln Town Car transmission problems might be, but you won’t truly know unless you have the right tools and experience. A good mechanic or transmission repair center will be able to connect your truck to a computer and find out which diagnostic trouble codes (DTC’s) have been stored. Once they know what to look for, they can perform a visual inspection to verify the problem.
How is a Lincoln Town Car transmission replaced?
In order to replace your Lincoln Town Car transmission, the truck has to be lifted from the ground in order to gain access to all of the parts that will need to be unbolted. Then the transmission can be lowered to the ground (typically with a transmission jack), so the new transmission can be installed. Once it is in place, for the 6L80, the vehicle PCM will have to be reprogrammed / reflashed to accept the new transmission using the latest GM subscription.

How to Solve Lincoln Town Car Transmission Problems
Solution A: Buy a Used Lincoln Town Car Transmission
The quickest way to fix your transmission problems is to simply buy a used transmission or used transmission. These can be found at most junk yards, and they often come with a 30-90 day warranty. However, there’s no way to determine the actual condition of the internal components, so you could be spending a bunch of money to have the exact same problems. Plus, that warranty only covers the transmission if it’s defective, not the labor costs that you’ll have to pay.
Solution B: Buy a Rebuilt Lincoln Town Car Transmission
Another option would be a rebuilt transmission or rebuilt transmission. A local repair shop will remove your transmission, then install a bunch of new parts during the rebuild. The problem here is, the skills and experience of each transmission rebuilder will vary widely from shop to shop, so you could have problems from something that wasn’t adjusted properly. And the 1-2 year warranty might only cover you at certain transmission repair shops, in a specific geographical area.
Solution C: Buy a Remanufactured Lincoln Town Car Transmission
Many owners depend on their vehicle to commute and get things done. Their gasoline engines are designed to go 100’s of thousands of miles, so it makes sense to invest in a remanufactured transmission.
