My 2000 Tacoma 5 speed, 200,000 miles, is having trouble shifting into 3rd and 4th gear. It feels like the shifter isn't moving far enough to fully engage those gears. It started pretty quickly. Sometimes it will not get into gear and require another shift to engage. It feels like the shifter should move 2" further. I'm thinking some kind of linkage problem, like a worn linkage bushing. All other gears are OK and shifter moves as it should. In 3rd and 4th, it doesn't feel like the shifter has clicked into position, it stops before a click is felt. Thanks
