Extend The Life Of Your Dodge Dart A727 Transmission With These Tips

Posted by on Thursday, January 22nd, 2015

The A727 is a 3-speed automatic transmission designed and built by the Chrysler Corporation. It is an older model automatic transmission that lacks the overdrive gear(s) found in all modern-day automatic transmissions. The A727 originated for the A488 transmission, which was formed from a very heavy cast-iron case and removable torque converter housing. The A727 differs from the A488 in that it uses a one piece case / torque converter housing and is made of lightweight, but very strong aluminum. The first A727 Torqueflite transmission went into production in 1962, and was eventually phased out of production in 1991, when it was replaced by the A518—basically an A727 transmission with an added overdrive gear. The A727 transmission is the bigger, stronger brother to the A904 transmission, and was used in most heavy-duty and high-performance applications. It could be found in almost every vehicle Chrysler produced during that time period, including the Plymouth Fury, the Dodge Coronet, the Dodge Charger, the Ram series of pickup trucks, the Plymouth Duster, and the Dodge Challenger. It could also be found in the Dodge Dart GTS.

What To Do If The 4L60E Transmission Starts Acting Up In Your 1995 Z28

Posted by on Tuesday, January 20th, 2015

The 4L60E is a four speed automatic transmission designed and built by General Motors. It is heavily based on the very first automatic over drive transmission built by General Motors, the 700R4. Besides some fixes to repair very early 700R4 transmissions, the biggest difference between the two in that the 4L60E is a full electronic transmission.  The 4L60E transmission comes from a family of transmissions that include the 700R4, the 4L60 and the 4L65E. The 700R4 is equipped with a very steep 3.06:1 first gear ratio which help give this transmission and the vehicle it is installed in excellent off the line performance.

Likewise, the 4L60E is equipped with a very sweet over drive gear ratio of 0.70:1 (30% over driven) that really helps increase gas mileage, especially at highway speeds.  The 4L60E found its way into many GM vehicles, including the Chevy Suburban, the Corvette, The Impala SS, the Silverado full size pickup truck, the GMC Jimmy and the S-10 Blazer. It could also be found in the Chevrolet Camaro.

Add A little Muscle To The A4LD Transmission In Your Ford Ranger

Posted by on Wednesday, January 7th, 2015

The A4LD is a very early automatic over drive transmission built by the Ford Motor Company. It is really nothing more than an earlier C3 three speed transmission with an overdrive gear added. It is a fairly weak transmission that was used only behind four and six cylinder engines. It was eventually replaced by the 4R44E automatic transmission that featured a fully electronic valve body, something the A4LD lacked. The A4LD first went into production in 1985, and remained a viable optional transmission through the end of the 2002 model year. The A4LD was used widely throughout the Ford brands of the time (including Mazda) and could be found in vehicles like the Ford Bronco II (smaller of the two Bronco models), the Ford Thunderbird, the Ford Mustang four cylinder models only), the Ford Aerostar minivan and the Ford Explorer. It could also be found in the Ford Ranger.
