When I was looking for replacement transmission cooler hoses I searched through images of aftermarket formed hoses, then ordered a few different hoses until I found shapes that would fit. Gates makes quality hoses IME. Continental also. I avoid anything made in chy nuh.
Another option would be to search through other Toyota models/years to find a hose that might fit, or which could be cut to fit.
