4EAT Transmissions for Sale: Subaru, Ford and Mazda Transmissions..

The 4EAT Transmissions are a 4 speed, microprocessor-controlled transmission that was first introduced in 1987.5 Subaru models. It is not a 3 speed transmission with overdrive. It features a lock-up torque converter which locks up in all forward gears except 1st. It has been offered in FWD or Full Time-AWD configurations.

The 4EAT transmission has undergone continuous development and improvement since its introduction.
Several unique 4EAT features have been added, changed, or deleted from various Subaru models over the years. We’ll provide you with a brief overview of these features here. For a more thorough description of specific 4EAT operating characteristics or features, refer to the applicable Subaru service manual for the year and model Subaru
you are working on.

Some Subaru models were equipped with a
1-HOLD button. These include:
• 1987.5-91 XT and XT6 models
• 1988-89 “L” series
• 1990 Loyale

An enhanced version of the original 4EAT was introduced with the 1990 model year Legacy. Although similar in design to the original 4EAT, the shift quadrant is different. The Legacy 4EAT has a seven position quadrant: P-R-N-D-3-2-1. The 1-HOLD button has been deleted and a manual button was added. Subaru vehicles
equipped with the manual button included:
• 1990-94 Legacy
• 1993-94 Impreza
• 1992-97 SVX
When the selector is in 3rd range with the manual switch “ON,” the transmission will start in 2nd gear and shift to 3rd. In 2nd range manual, the transmission starts and stays in 2nd gear, but will up-shift to 3rd gear at 6500 RPM to prevent damage to the engine. In 1st range manual the transmission stays in 1st gear and also will up-shift to second at 6500 RPM to prevent damage to the engine.

Additionally, on AWD vehicles, the TCU applies a more aggressive AWD range when the selector is in the 1st position, manual switch “ON” or “OFF.” These changes result in improved drive-ability on low friction road surfaces.
The TCU monitors various engine and vehicle inputs, i.e., throttle position and vehicle speed, etc. It also controls the electronic shift solenoids in the transmission.

The 4EAT transmissions are also used in many smaller Ford cars and Mazdas as well. We all know Mazda and Ford use many similar engines and transmissions, since Ford owns Mazda.
