A4LD Transmission repair manuals (4R44E /4R55E) A4LD transmission — information about rebuild (4R44E /4R55E) The main purpose of the automatic transmission A4LD (4R44E / 4R55E) is installed on rear-wheel drive cars with engine size ranges from 2.5 to 4.0 liters. The gearbox is not possible to change gears manually, but it is a sports mode. Wow, those are more than annoyances!! The A4LD is the single worst transmission out there. They are notorious for failing well before 100,000 miles even with proper maintenance. It sounds to me like you're having valve body problems. The first place to start would be with a proper tranny flush, filter replacement, and new fluid. The A4LD was derived from the C-3 three-speed automatic transmission by placing a two-speed overdrive unit in front of the original three-speed workings. As the names imply, the 'E' transmissions are electronically controlled (similar to the AOD-E/4R70W transmissions), while the 5R55E is a five speed version currently used only with the SOHC 4.
