R4A51

The 4-speed automatic transmission R4A51 (V4A51) was used since 1997 for RWD Montero models with engine capacity from 3-liters. In a couple of years, the new 5-speed R5A51 (2000-2006) and AWD V5A51 versions were launched. This family of automatic transmissions competed with RWD AW30-40LE by Aisin.
