Hello, I am a new toyota owner and i have been having a small problem with my rig. The problem is whenever i go to put it in gear (it is a 5spd) it is very difficult to put in in gear. I put the transfer case in N and it makes it easier to shift through the gears. but when i put it back in 2H 4H OR 4L it is hard again. Also, if i work the transfer case a bit it makes it a tad bit easier. Can anyone tell me what the problem is? And by the way i have a 1999 4runner sr5. Any help is appreciated.
