03-72LE A43DE A46DE Transmission Master Rebuild Kit

This is a complete master overhaul kit for the Aisin-Warner 03-72LE four-speed automatic, also cataloged as the A43DE, A46DE, and A46DF. It carries the friction plates, steel plates, paper and rubber gaskets, lip seals, sealing rings, and thrust washers you replace during a full teardown, so you are not stopping partway through the job to chase individual clutch packs and seal sizes.

It fits the rear-wheel-drive Aisin four-speed used behind the small four-cylinders in the Suzuki Sidekick (1989-1998), Vitara and Grand Vitara (1999-2012), X-90 (1996-1998), and XL-7 (2001-2003), the Geo and Chevrolet Tracker (1996-2004), the Kia Sportage (1995-2002), and the Mazda Miata/MX-5 automatic (1998-2005). Confirm your unit is stamped 03-72LE, A43DE, A46DE, or A46DF before ordering, since some of these chassis were also built with a three-speed automatic that this kit does not cover.

Reach for it when the transmission slips on the 2-3 shift, flares between gears, or weeps at the pump and output seals after high mileage. On the bench you strip the unit down, replace every clutch friction and steel in the forward and direct drums, lay in the fresh gasket and lip-seal set as the pump and case go back together, and set clutch clearance with the new steels. The frictions use high-energy material for a stable friction coefficient, and the rubber is oil- and heat-resistant so the rebuilt drums hold line pressure. Ships from the USA.
