| This rarely happens, but can on any stick car. You were sitting in JUST the right spot were the gear teeth could not mesh. Happened to me on every car I drove at least once. Cure: Try 2nd and then first, this moves the gears just enough, or let off the brake to roll the car just slightly.
Yeah, it's a weird thing if it happens at a light. But it's not a tranny problem. Just dumb luck. |
