2009 Mercury Mountaineer Automatic Transmission

• The solenoid pack, commonly responsible for electrical shift related issues in this family, has been completely remanufactured in-house, including disassembly, cleaning, and testing independently. • To prevent overdrive planet failure due to lack of lubrication and to increase durability, the planets have been rebuilt and TIG welded. • To combat erratic shifting due to high wear, the servo and servo pin have been realigned and modified using inhouse custom tooling and bushings. • The completely remanufactured pump, with a new pump cover bushing machined in place and a new flow control valve, has been assembled in a custom alignment fixture to provide consistent internal pressures, improved lubrication, and eliminate noise, slipping, and delayed engagement. • To prevent torque converter vibration and damage, we’re provided, installed, and aligned a flex plate adapter. • The pump also features a custom-spec front stator bushing and a new rear bushing to better support the input shaft and improve lubrication control. • Fully tested on our custom-built, custom-programmed dynamometers with Synthetec ATF, the 5R55S/W is cold-, hot-, load-, and road-tested. • Every transmission is cold-and hot-tested using a proprietary dynamometer testing program that includes fully synthetic automatic transmission fluid and a filtration system.

Read the fine print…

You might notice that some competitors offer lower prices, but they charge additional fees for every subsequent step. In contrast, our shipping charge covers the cost of returning your Core product, while others charge you or require you to pay for it.

To maintain our affordable prices, we kindly request the return of your old transmission (the core). We’ve made the process convenient for you. After installing your remanufactured unit, simply contact us to arrange a FREE core pickup.

We’ll cover the shipping costs!

Please schedule the return within 30 days. If you opt for the “Waive Core Charge” option, your card will only be charged if the core isn’t returned. If you need more time, please let us know. Remember, the warranty is contingent on returning your core.

While we disclose your flat-rate shipping upfront, other companies may require you to purchase an upgrade to qualify for the lower shipping cost.

We deliver your remanufactured transmission promptly and reasonably to any commercially zoned business address within the continental United States. In stock orders typically ship within 24-48 hours and arrive within a few business days after shipping. However, please note that residential or liftgate deliveries incur an additional $99 fee.

Although every shipment is carefully inspected before it leaves our facility, unexpected issues can occur in transit. Please examine your delivery as soon as it arrives and report any concerns right away. Our top priority is your complete satisfaction.
