I have a 89 fj62 with 219k miles on it and love the thing. Problem is the tranny won't engage until the vehicle warms up which takes approx. 3-5 minutes. Also, when trying to pass or going up a hill, the tranny won't shift down. Any thoughts or suggestions? By the way, I am new to the site and must say it is awesome thus far like alot of your rigs.
