Take Steps to Prepare the AX4N Transmission in Your Ford Taurus Station Wagon before Your Family Vacation

Posted by on Tuesday, September 2nd, 2014

The AX4N is a four speed automatic transmission designed and built by the Ford Motor Company. It is based heavily on the AXOD transmission and comes from the same family as the 4F50N transmission. This transmission tends to be troublesome with many intermediate clutch failures that lead to poor quality 1 – 2 shifts. There are also reported problems with the neutral to drive accumulator that result in harsh shifting of all forward gears. Another issue to beware of is failure of the parking pawl, which can lead to the car coasting downhill on its own after having been parked. The AX4N was first put to use back in 1994 and remained a viable option through the end of the 2007 model year. This transmission could be found in many Ford products, including the Taurus SHO, the Lincoln Continental, the Mercury Sable, the Ford Windstar minivan, the Freestar and the Mercury Monterrey.  It was also found in the station wagon version of the Taurus.

Add Some Muscle to the C6 Transmission in Your Ford Full Size Bronco

Posted by on Monday, September 1st, 2014

The C6 is a three speed automatic transmission designed and built by the Ford Motor Company. It was lighter and had a greater torque capacity than its MX transmission predecessor. The C6 was also marketed as the SlectShift Cruise-O-Matic transmission. This transmission used an aluminum case, a non-electronic valve body, and a Simpson planetary gear set. The C6 transmission was eventually replaced by the four-speed, overdrive E4OD transmission. Care should be taken when replacing the C6 transmission because it made use of a total of five different bell housings, designed to fit the many different engine blocks Ford produced at the time. The C4 was first put into use (in the Ford Fairlane) in 1964 and remained in production up through the end of the 1991 model year. This transmission could be paired with many different ford vehicles, including the F-series pickup trucks, the Galaxy, the LTD, the Ranchero, the Thunderbird, the Torino and a host of Mercury cars, including the Comet, the Cougar, the Montego and the Monterey. It was also used in the then new full-sized Ford Bronco.

The Bronco came with a number of engines, and new buyers had a choice between a six-cylinder engine, and multiple V8 engines, including the 302, the 351M and 400M engines.

The U660E automatic transmission can be found in many Toyota and Lexus vehicles, including the Estima, the Camry, the ES 350, the Aurion, the Venza, the RX350 and the Sienna.
