Disadvantages, breakdowns and problems of Aisin AW50-40LE
The automatic machine of a proven design breaks down infrequently and only at high mileage
Its only weak point is the cracking Forwad-Direct drum.
Often the torque converter seal leaks, a little less often it oozes from the axle shafts
A drop in oil pressure is fraught with accelerated wear of the mechanical parts of the automatic transmission
