Furthermore, repairing the shift solenoids in your transmission mechanism is between $300 and $850, while paying for a transmission flush every 20,000-60,000 miles is only $100 to keep your transmission healthy. Let’s see how much the average Mercury transmission repair cost in different Mercury models over the years.
Mercury Cougar
The Mercury Cougar is a series of cars sold by the Mercury division of FFord Motor Company between the model years of 1967 and 1997 and the 1999-2002 models. Although the nameplate is generally for two-door coupe styles, the Cougar was also sold as a four-door sedan, wagon, hatchback, and convertible body style.
Sold in eight generations, the Cougar was a popular vehicle that was produced for over 3 decades. Although the Cougar had a favorable sales record, it also was prone to a high Mercury transmission repair cost.
The worst model years of the Cougar in terms of repair prices and reliability focus on the 1999-2002 years, with the 2000 having the most-reported problem of the alternator failing. The other top issues across every model year are the transmission failure in the 2002 Cougar, costing the owner around $2,500 to repair, and the 1999 Cougar throwing a bearing, costing around $4,500 to fix at around 82,000 miles.
The main problem categories in the 1999 Mercury Cougar focus on the engine, electoral system, fuel system, AC and heater, and the interior accessories, with some owner complaints regarding the high Mercury transmission repair cost. The transmission problems focus on the car kicking out of gear multiple times during use.
However, the most problematic year in terms of a high Mercury transmission repair cost is the 2002 Cougar. The transmission failure cost owners around $2,500 to repair or replace the faulty part.
Mercury Grand Marquis
The Mercury Grand Marquis is a vehicle produced by Ford Motor Company between the 1975 and 2011 years, with the class being a full-size option and the platform based on the Ford Panther platform. Produced over four generations, the Grand Marquis is a staple of the Mercury division – however, not without its fair share of complaints regarding the expensive Mercury transmission repair cost.
Along with the high Mercury transmission repair cost, the Grand Marquis has had problematic years from 2003-2005, with the 2005 having the most-reported issue of the headlights not working properly. Along with the lighting concerns, the Grand Marquis has owner complaints of the intake manifold failing in the 1997 year, costing the owner around $1,700 to fix, and the valve dropping in the 2007 Marquis, costing nearly $3,300 to repair.
In the 2005 Grand Marquis, the main problem categories focus on the lights, seat belts, airbags, body and paint, AC and heater, engine, and transmission, with owners stating the transmission slips when the car gets wet. In this case, the best solution is to replace the sensor for around $240 and $290.
Although this repair can be considered tedious and annoying to pay for, it is a relatively low Mercury transmission repair cost compared to a full transmission replacement in some models.
Mercury Mariner
The Mercury Mariner is a compact crossover SUV introduced in 2004 for the 2005 model year. Produced on a front-engine and front-wheel-drive layout, this 5-door SUV uses the Ford CD2 platform. Winning awards for the ‘best buy’ by Consumers Digest for three years running between 2005-2007, we can see this is a popular and reliable car – unfortunately, it still is susceptible to an expensive Mercury transmission repair cost.
The worst model years of the Mercury Mariner are the 2008-2010 years, with the 2008 having the most-reported issue of the power steering failing. The other top three concerns focus on the transmission system, with reports of the transmission failing in the 2006 and 2007 Mariner, costing owners between $3,300 and $3,700 for the Mercury transmission repair cost.
The 2008 Mercury Mariner is the least reliable model, with the main problem categories focusing on the power steering, transmission, and engine. Owners cite that the transmission lurches forward, the car revs high and slips, the transmission dies during use, and the car does not shift properly.
Mercury Milan
The Mercury Milan is a midsize car produced by the Mercury division of Ford between 2006 and 2011, with the intent to replace the Mercury Sable and Mercury Mystique as a small-size sedan. With the option of a 5-speed Mazda G5M manual transmission, 6-speed Mazda G6M manual, 5-speed Mazda automatic, 6-speed Aisin automatic, or 6-speed Ford 6F35 automatic, you would assume that the transmission choices would lead to reliability – instead, the Milan is known for a high Mercury transmission repair cost.
The most problematic years of Milan focus on the 2006, 2008, and 2010 years, with 2010 having the most-reported owner problem of the power steering no longer working. The other concerns from owners focus on the soft brake pedal in the 2008 Milan, costing around $2,000 to repair. The transmission failure in the 2006 Milan, coming to about $1,900 for the Mercury transmission repair cost.
In the 2010 Mercury Milan, the steering system, engine, lights, and transmission are the most problematic categories, with owners stating that the transmission slams into gear while shifting and the transmission fluid leaks.
Mercury Mountaineer
The Mercury Mountaineer is a mid-size SUV produced between the model years 1997 and 2010, playing to the market who bought and loved the Ford Explorer. Built virtually the same, the external features were somewhat different than the Ford counterpart. Despite the popularity, the Mountaineer was discontinued at the end of 2010, dropping from the best-selling vehicle in 2000 to the worst-selling Mercury in 2010.
The drop in popularity can be attributed to various problems, like the Mercury transmission repair cost, engine concerns, and the cracked rear panel in the 2004 model year. The other most concerning problems across all years of production focus on the transmission failure in the 2002 Mountaineer and the transmission slipping in the 2006 Mountaineer.
In the 2002 Mountaineer, the most problematic categories are the transmission, interior accessories, and the body and paint category. Owners cite transmission failure, the check engine light coming on, the gear shifter falling off, and the switch box failing. Fixing the transmission failure has a very high Mercury transmission repair cost. Owners need to replace the transmission, rebuild the transmission, replace the gasket, or replace the intermediate band for around $2,340.
Mercury Sable
The Mercury Sable has been produced from the 1986-2005 and 2008-2009 years, with this model being the replacement for the Mercury Marquis. Even with over two decades of production, the Mercury Sable is highly susceptible to an expensive Mercury transmission repair cost.
The worst model years of the Sable are the 1997, 1998, 2000, 2002, and 2003 years, with the 2003 having the most-reported owner problem of the gears not engaging. The other top two problems in the Sable focus on the transmission failure in the 2005 Sable and the torque converter failing in the 2002 Sable, costing owners around $1,800 to repair.
The 2003 Sable is often considered the worst model due to the lack of reliability and the high repair costs associated with the numerous problems. The main categories of concern are the transmission, electrical system, and engine. With owners stating that the transmission does not engage, the transmission jerks when stopped, and the car accelerates on its own.
The expensive Mercury transmission repair cost in the 2002 Sable can often be attributed to the lack of engagement. Owners need to rebuild the transmission for around $2,220 and occur at nearly 92,000 miles.
Mercury 2007 Recall
In 2007, Ford recalled nearly 1,500 vehicles due to issues with the 4.6-liter and 6R transmission. The recall focused on the 2008 Ford Explorer, Ford Explorer Sport Track, and Mercury Mountaineer cars that had issues with the bolts of the oil line fittings, causing the bolts to come undone.
As a result of the construction error, the bolt may loosen, and the oil cooler lines could disengage from the transmission. If this happens, the transmission fluid would leak in the car, causing a high Mercury transmission repair cost.
Mercury 2012 Recall
In 2012, Ford recalled certain 2004-2005 Mercury Monterey vehicles due to a failed torque converter output shaft, resulting in an expensive Mercury transmission repair cost. This torque failure results in a sudden loss of power without warning to the driver, highly increasing the risk of a crash and safety issues while driving at high speeds.
The owner is in charge of replacing the torque converter in order to keep the car’s transmission functioning at the proper level.
The Bottom Line
The Mercury transmission repair cost is dependent on the severity of the problem and whether you have to pay for a full replacement or a smaller transmission repair. By looking at the different models in production, like the Monterey vs. the Mountaineer, you will be able to calculate how much you will spend on fixes!
