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.

That being said, you don’t want to get stuck with a faulty transmission and have to go to the expense and trouble of fixing it. So, it’s a good idea to learn how to test drive an automatic and make sure that you’re getting the car you need. Continue reading…

Get the 700R4 Automatic Transmission in Your GMC Ready for the Snow Plowing Season

Posted by on Thursday, September 25th, 2014

The 700R4 automatic transmission was one of General Motors very first overdrive automatic transmissions. It has four speeds, with the fourth gear having a 0.70 (30%) overdrive ratio. GM designed the overdrive transmission in order to meet stricter CAFÉ (company average fuel economy) standards. It is based somewhat on the earlier three speed TH350 transmission. The 700R4 was eventually replaced with a full electronic version of the transmission and renamed the 4L60E. The 700R4 was used extensively in the General Motors lineup, and could be found in such vehicles as the Corvette, the Impala, the Firebird, the Syclone, the Blazer (both full size and the S-10), the Suburban and the Chevrolet C/K. It was also found in the GMC Jimmy.

Posted by on Tuesday, September 23rd, 2014

The 4R70W is a four-speed automatic transmission produced by the Ford Motor Company. It comes from a family of Ford overdrive transmissions that also includes the AOD, the AODE and the 4R75W. Similar to most automatic overdrive transmissions of that time, this transmission incorporates a case of aluminum construction, a fully electronic valve body and a lockup torque converter. This transmission uses a first gear ratio of 2.84:1 and a final overdrive gear ratio of 0.7:1 (30% over driven). The 4R70W transmission was first used in a production vehicle back in 1993 and remained an optional transmission through the 2004 model year. This transmission was widely used throughout the Ford and Mercury lineup. The Thunderbird, the Crown Victoria, the Explorer, the Expedition and the Mustang all used this transmission. It was also found in the F150 pickup truck.

Turning Off Your Car’s Overdrive: Is There Any Benefit?

Posted by on Thursday, September 18th, 2014

Overdrive transmission - neutral - Wiki

While you may be tempted to take your car out of overdrive, you need to understand how it works first.


Overdrive is a pretty hotly contested feature among car aficionados. The difference usually boils down to a preference for either power or fuel efficiency, but, of course, there are situations when you need both. The most important thing to think about when considering this question is what purpose overdrive serves and whether that purpose fits your needs as a driver. As in most cases, function should ultimately be the guide. Continue reading…

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.
