So! Here's the issue:

- With the clutch engaged, I get a grind and crunch (wizzzzzclunk) when shifting into 3rd (especially), 4th, and reverse (sometimes). 1st and 2nd are fine.

- Sometimes, with the clutch engaged, I can't shift into 3rd at all

- After shifting into third, if I keep the clutch engaged I can shift in to any gear, including 3rd, without grinding


Possibly related information:

Immediately before this started happening, I broke the water-pump/fan belt. So I pulled over (when I noticed the temperature rising rapidly) and had the car towed home, about 25 miles. Then I replaced the belt. I noticed the problem during my drive around the block to test the work I'd done. I NEVER had this problem pre-tow, only afterward. Also, while the guy was hooking my car up to the truck, he pulled it forward about 3 feet with it in gear (don't know which) and engine off. He shifted it into neutral -- naturally -- for the tow home. I don't mean to sound like I'm blaming the tow guy, just listing all possibly pertinent info.

What I've done:

Thinking that stranger things have happened, I considered that I'd somehow gotten air into my clutch line, so I bled it (bottom up). No air in there and the clutch seems to engage just fine. Feels even better than before, in fact. But the problem, exactly as it was pre-bleed, persists.


That's the problem. What ought I to do next?

Thanks, fellas!
The vehicle was towed with the rear wheels on the ground and the transmission in neutral? It was towed in this condition for 25 miles?

That could cause some problems. These transmissions are splash lubricated, the turning gear set throws fluid around the inside of the case. There is a lower gear set and an upper gear set, the lower gear contacts the fluid directly, the upper gear set does not. When the car is towed in neutral the upper gearset which is connected to the output shaft turns without the benefit of the tranny fluid bathing it.

The first thing you probably need to do is to check the transmission fluid level and condition.
