Mercury Sable Transmission Recalls

Mercury Sable Technical Service Bulletins (TSB)

TSB 03-12-3 – Torque converter clutch not engaging and/or OBDII trouble codes P0741 or P1744
1996 – 2003 Ford Taurus – 1996 – 2003 Ford Windstar – 1996 – 2002 Lincoln Continental – 1996 – 2003 Mercury Sable
Problem – Drivability issues can result when the torque converter clutch will not engage when commanded. This can be caused by a number of issues including a worn out AX4S torque converter, or a sticking TCC solenoid.
Solution – Replace torque converter and/or TCC solenoid

TSB 10-22-4 – AWD vehicles – Shudder/chatter/vibration on turns or thump/clunk noise on light acceleration – 6F Transmission
2010 Ford Fusion – 2010 Ford Taurus – 2010 Ford Edge – 2010 Ford Flex – 2010 Mercury Milan – 2010 Lincoln MKS – 2010 Lincoln MKZ – 2010 Lincoln MKT – 2010 Lincoln MKX
Problem – Certain vehicles built between 10/1/2009-12/31/2009 equipped with all-wheel-drive, may experience a shutter or vibration in the driveline during a tight turn. They may also experience a thump or clunk noise during light acceleration. These symptoms may also occur under 40 mph (64 KM/H), when driving uphill or towing under heavy acceleration.
Solution – Installing a properly remanufactured PTU (Power Transfer Unit— a simplified transfer case) may solve this problem.

TSB 11-12-10 – Sluggish acceleration from 0-5 mph (0-8 km/h) followed by harsh bump or slip on takeoff – 6F35 Transmission & 6F50 Transmission
2010 – 2011 Ford Taurus – 2009 – 2011 Ford Edge – 2009 – 2011 Ford Flex – 2011 Ford Explorer – 2010 – 2011 Lincoln MKS – 2009 – 2011 Lincoln MKX – 2010 – 2011 Lincoln MKT
Problem – Some vehicles may experience sluggish acceleration or a hesitation feel during a rolling stop, followed by a harsh bump or slip feeling. This can be caused by a design flaw in the 6F35 valve body / 6F50 valve body.
Solution – On transmissions originally built for Mercon LV transmission fluid (listed on the dipstick), the valve body will have to be modified by deleting one hole in the valve body separator plate, and removing the check ball in the area of the deleted hole. If this modification is not performed properly, the transmission may experience a loss of reverse or a 2-3 shift flare.

Can I drive with a transmission problem?

If your Mercury Sable 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 Mercury Sable transmission need to be replaced?

The overall lifespan of a Mercury Sable 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 Mercury Sable 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 Mercury Sable transmission issues diagnosed?

It is fairly easy to guesstimate what the root cause of your Mercury Sable 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 Mercury Sable transmission replaced?

In order to replace your Mercury Sable 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 Mercury Sable Transmission Problems

Solution A: Buy a Used Mercury Sable 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 Mercury Sable 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 Mercury Sable 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.

Never made any noise or slipped or pulled hard, we stopped for a red light and it would not move. Engine never stopped running and I don’t have any problems shifting through gears. It just won’t move.

I have been driving a 2004 Mercury Sable and it has been shifting kinda weird, at times a bit early others a bit late. It seems to have a difficult time accelerating at lower gears until I got up to about 40 to 60mph on the interstate. However last week it would only go into 1st for a few seconds before swithing to neutral and this happened constantly until I got home. I have very little idea what could cause this.
