Hey all, it's too bad this is my first post but here goes:
Bought a '90 2WD Dually, and drove it home, have put maybe 1000km on it so far and worked great the whole time. In the last couple hundred km's I noticed that sometimes if I shifted into 2nd at a stop light or something, as soon as I'd let the clutch out to get going it would pop out of second and I'd have no drive, even though the lever was staying in. I'd grab neutral and re-grab second, and it would go in and I could drive off. Now it started popping out of fourth, for example if I'm coming up to a slower corner and downshift into 4th, it decelerates in 4th ok, but as soon as I roll onto the throttle it will just pop out (shifter feels like it's half-out of gear, but not in neutral), then if I just grab the shifter and try to grab fourth it would grind. Now it's started to grind when shifting from 3rd to 4th, so I've stopped using 4th altogether.
Any ideas what my culprit is?
