Hey all
So I just went to start my car up and reverse out of the garage, and I found that I was unable to put it into any gear. When the engine is off, I can quite easily move the shifter into each gear position, but when the engine is running there is absolutely no way. The gates feel 'blocked off', and when I push against each gear location the car will very lightly creep forward (or backward if I push against reverse). If I turn it off, put it in gear, hold the clutch pedal down, then turn the engine on the car behaves as if I wasn't holding the clutch pedal down and lurches forward or backward depending on the gear.
This has literally happened overnight. A run down of events yesterday: I pushed my car backwards out of the garage to wash it. Once I was finished, I turned the engine on and let it idle for a minute or so before shifting it into 1st and driving forward into the garage before taking it out of gear, applying the handbrake and turning it off. That is where it has sat until tonight.
