What model Jerico is it? Is it a DR4 or a DR4-4? i would take the 3-4 shift fork out and make sure that the groove that fits in the shift arm is not worn. That makes it hard to stay in adjustment. Also, the shift rails can be worn. It basically can be in one gear part way and you happen tp be strong enough and have enough leverage to break it, especially if you have a long shifter and long shift arms. I would suggest taking the top off with the shifter on and running it through the gears on the bench before you put it back in the car.
