very classic toyota automatic gearbox "saniplast fix" - if the gearbox is too slushy (due to bad regulating valve and bad feed limit valve) - dumbasses tighten the aggression cable and think its fixed.
While now its actually destroying itself at rapid pace. There is a reason toyota have specced a cable length not a tightness in the manual.
I had repaired hundreds of those cases, Good money for people like me, keep it up !!
