As my trusty truck enters middle-age, it is starting to show a few signs of 1000+ ft-lbs of torque going through it's little 450ft-lb rated 5 speed. At about 160k miles the thing started to get very difficult to put in gear when stopped. Sometimes, nearly impossible. Other than that, it shifts fine once its moving. It's had it's expensive magical mystery oil changed every 50k miles or so. The clutch master/slave cylinders appear to be working correctly. The clutch was replaced at 90k with a South Bend O-FE, along with the usual pilot bearing and clutch release bearing.
Any ideas what else to look for?
