My trans had been making terrible noises. Only does it in very heavy loads. Just today I was driving and pulling through 1,2,3 and came into a corner, downshifted to 2nd and it grinded like i accidentally hit reverse. Except, It didnt hit reverse it continued to grind in 2nd and wouldnt go in. I came to a stop, shifted it into 2nd and let out the clutch and it felt like my emergency brake was fully engaged except it wasnt. 2nd is literally frozen. Ever heard of this before?
2nd/3rd pull:

I have a sneaky idea that you pulled on the shifter pretty hard, trying to get it into 2nd. I will bet dollars to donuts, that you have now forced it into two gears at once. Causes, worn shift coupler/ bushing, broken motor mounts, or shifter way out of adjustment. More then likely you will have to pull the trans. If you try and jerk it out with the shifter, you will probably break the hockey stick. _________________ 69 road Bug 2110

Absolutely impossible. VW designed the shift rods with an interlock plunger to prevent this. _________________

Its not stuck in 2nd. I drove it home using 1st 3rd and 4th with no issue. _________________ 1969 Type I

With a trans in good condition, all 4 gears have one of each gear pairs freewheeling while in neutral. When you try to pull it into 2nd, the synchro grabs onto the 2nd gear idler and speeds up (or slows down) the entire input shaft including clutch disc until the rpms match the road speed for 2nd gear. If there is something else preventing the input shaft from spinning freely in neutral, it will grind like you describe.
I bet there are loose or broken bits associated with the noise you've been hearing recently that are now preventing the input shaft from spinning.

Or a broken 1-2 shift fork.
Time for a trans rebuild. _________________

Sorry Bruce, but you might think that you have seen everything, but in this case you haven't. You can search the threads, because I and other on here have seen it happen. Just because it was designed not to happen, doesn't mean that it can't after 40 years of abuse. It might not be his problem, but it does occur. _________________ 69 road Bug 2110

The only way it can happen is if the interlock pin is left out by mistake. If that happens, you will find out soon after installing the gearbox.
If the interlock pins are in place, no amount of abuse or wear is going to allow two adjacent gears to engage at the same time. _________________

I'm gonna have it rebuilt. I'll report back the findings when it's split open _________________ 1969 Type I
