Off Roading the Dunes: Is Your Ram’s A727 Transmission Up to the Task?

Posted by on Monday, November 17th, 2014

The A727 is a three-speed automatic transmission designed by the Chrysler Corporation. It is mainly found in two-wheel drive vehicles, although it can be used in four-wheel drive applications in conjunction with a transfer case. Internally to Chrysler, the A727 is also referred to as the 36H or the 37HR. Chrysler eventually replaced it with the four-speed A518 and A618 transmissions. Most A727 are purely mechanical transmissions, although some of the later versions incorporated a lockup torque converter that required the use of an electrical solenoid. The A727 is considered a very heavy duty transmission. It was built alongside the A904 transmission, which was a weaker version of the A727. Compared to modern multiple speed transmissions, the A727 comes equipped with a poor first gear ratio choice of 2.45:1. This helps neither mileage nor low-speed take off. The very early A727 transmissions were heavy cast iron units. Starting in 1962, Chrysler started producing the transmission with a lightweight, but strong, aluminum case. Chrysler continued to produce the A727 through 1991, when it was finally replaced because engineers needed a transmission with more gears to meet new strict CAFE mileage laws. The A727 was used widely throughout the many Chrysler brands, and could be found in vehicles like the Hemi-powered Road Runner, the Plymouth Fury station wagon, the big block Dodge Darts, the high speed Dodge Daytona’s and the 340 six-pak Dodge Challengers. Chrysler also used them in Dodge Ram trucks.

Is the Vibration in My Dodge Challenger Coming from My A727 Transmission?

Posted by on Monday, September 29th, 2014

The A727 transmission is a three-speed automatic transmission designed by the Chrysler Corporation for use in Dodge, Chrysler, Plymouth and AMC vehicles. Unlike all modern day automatic transmissions, this transmission does not include an overdrive gear. Instead, it features a 1:1 final drive ratio that makes it unfit for keeping up with modern day traffic and high speeds. Very early Torqueflite transmissions were made from heavy cast iron and featured push button shifters.

In 1962, they started manufacturing the transmission from lightweight aluminum and switched over to a more conventional style shifter. The A727 was first put into production in 1962 and remained in the line up all through the end of the 1978 model year.  This transmission came in two types — one with a bolt housing pattern for small block engines and the other for big block engines.  There was also an odd ball AMC bell housing.  The A727 was the most heavy duty automatic transmission made by Chrysler during the period, and it could often be found in pickup trucks, vans and high horse-power passenger vehicles.

How to Stop the A727 Transmission in Your ’77 Dodge Ram Pickup from Overheating

Posted by on Wednesday, September 17th, 2014

The A727 is a three-speed automatic transmission designed and built by the Chrysler Corporation. It is primarily designed to be used in vehicles with front-mounted engines and rear wheel drive, although it can be used in conjunction with a transfer case in four-wheel drive applications. Very early TorqueFlite transmissions used a cast iron case, which was both heavy and expensive. In 1962, Chrysler replaced the cast iron case with a stronger, but lighter aluminum one. In 1978, they added a lockup torque converter. The A727 transmission remained in this configuration up to its departure from the line-up in 1991. The A727 came with two different bell housing bolt patterns — one for small block engines and another for big block engines. The A727 was an option in many vehicles, including the Chrysler 300, the Newport and the New Yorker. It was also available in the Dodge Charger, the Challenger, the Dart and the Dodge Ram Pickup Truck.

Beef Up the A727 Transmission in Your Winnebago Motorhome

Posted by on Tuesday, August 12th, 2014

The A727 is a three-speed automatic transmission developed and produced by the Chrysler Corporation. It was originally called the A488 and built from heavy cast iron. In the early 1960s, Chrysler started producing the transmission with a much lighter aluminum case and called it the A727. It is sometimes also referred to as the 36RH transmission.

This transmission is equipped with a fairly average 2.45:1 ratio first gear and an industry standard (for the time period) 1:1 ratio final 3rd gear. The A727 underwent light changes throughout its life cycle, with the most dramatic being the introduction of a lockup torque converter in the late 1970s. The lockup converter was the first attempt to use changes to the transmission to increase gas mileage. The A727 was eventually replaced by the A518 transmission that incorporated a 4th overdrive gear.

The A727 transmission could be found in a very wide variety of vehicles, including the Dodge Ram pickup, the Dodge Ram Van, the Ramcharger, the Cornet, the Cuda, the Diplomat, and the Aspen. It could also be found in the chassis that were supplied to many of the motorhome builders of the time.
