i have a 60 series toyota land cruiser and i can not change gears from L4 to H2. i have checked all the hoses and they are all secure. the 4WD light is still on but when i switch the hoses around the 4WD light comes OFF but is still in L4 gear. it just wont come out. i have also done the usual "reverse" to try to lock it out of gear but that also does not work. any suggestions?
