Well, most of them go 200K or more before they require a rebuild. So I wouldn't say they are that bad. I had a 1991 full size GMC van that had to have the transmission rebuilt twice in 150K. And I am a fanatic when it comes to preventive maintenance.Im just getting to know the 4 speed automatic transmissions in the FJ62 series with the vaccum operated transfer.. Can anyone shed any light on these transmissions? any feedback welcomed..
