I have a 1986 4runner with automatic transmission. The thing is, I live in the dune area and climbing is the local sport. The 22r was modified and I really like how it performs with this transmission. At the critical point at the top of the dune, it doesn't change to first gear. I tried all the ways and it doesn't. I need to know what to do to make it work well. It doesn't change manually either, it stays in 2nd gear. please
I don't want them to tell me to change to a 5-speed manual, I've already had it before, now I'm here.
