I recently acquired a 240D with a one piece 4 speed. Haven't gotten around to troubleshooting why it doesn't shut off with the key, so I've been killing it in gear. Yesterday, I came out after work, and it was stuck in second gear. Shifted fine when I drove it to work. I got it home and disconnected the shifter rods and the shifter is free. The reverse arm is free to move, but the 1-2 and 3-4 don't move. Any ideas? The car is really not worth opening up the tranny.
