Posted by on Wednesday, July 16th, 2014

The A727 is a three-speed automatic transmission made by the Chrysler Corporation. It is the stronger of the two transmissions (the other being the A904) built during the muscle car area.

Great Accessories for the 4L85 Transmission in Your Chevy Suburban

Posted by on Monday, July 14th, 2014

The 4L85 is a very heavy-duty, four-speed automatic transmission made by Chevrolet and GMC. It shares many parts in common with its slightly weaker cousin, the 4L80E transmission. Both transmissions are based on the original TH400 three-speed transmission, with the addition of the overdrive gear and full electronically-controlled valve body. The 4L85 transmission is designed to handle up to 460 lb./ft. of torque in vehicles weighing in at up to 18,000 lbs. It has a nice, low gear ratio of 2.48:1, which really aids in takeoffs from a standstill, while still gaining a mileage advantage through the use of a 0.75 (25%) overdrive gear ratio. This transmission was built between 1991 and 2006. The 4L85 was used in a number of vehicles, including the Chevrolet Express van (only those equipped with the Duramax diesel engine), the Avalanche hybrid pickup/SUV, the GMC Yukon XL, and the Savanna van. It was also used in the Chevy Suburban.
