I have a 91 Toyota Pick-up truck. It has 150k miles on it. It is a straight shift (5 speed), Original clutch.
I am having problems with 3rd and 4th gear in it. What it is doing is basically, when I get the transmission hot (after 20 miles or so), I start to loose 3rd and 4th only.
When the transmission is cold, I can get into these gears fine. But if it is hot, I sometimes can get it into them, most of the time I can't.
I can also some times get it into gear if I slam it hard enough. Also, it seems that sometimes 4th will pop out of gear if I hit a big enough bump.
What could be causing this? Is this a synchronize problem?
It would be nice for your input, thanks in advanced.
