Transmission will not shift into gears when engine is running?

Hi,

If it can be shifted with the engine off and not on, the clutch isn't releasing the transmission.

The clutch on this vehicle is hydraulic. Brake fluid is fed to the clutch master cylinder from the brake master cylinder. First, confirm the brake fluid is full.

Next, I need you to check for any leaks. The clutch master cylinder applies pressure to a slave cylinder on the transmission which releases the transmission from the engine so you can shift. If either part fails, what you described can be the result.

I attached a pic below of the clutch master cylinder. It's an exploded view, but I highlighted the external portion that you can see when you open the hood. It will be mounted to the firewall of the vehicle below the brake master cylinder. First, confirm the brake fluid is full. If it is, then I need you to inspect the clutch master cylinder for leaks. In addition to checking under the hood, look up under the dash where the pushrod attached to the clutch pedal goes through the firewall. Make sure nothing is wet there.

Next, with the hood open, look on the transmission near where it connects to the engine for the slave cylinder. I attached a pic below (pic 2) to help. I highlighted the slave. I have a red arrow pointing toward the transmission. When you press the clutch, that slave cylinder pushes the metal rod outward which moves the release bearing on the clutch assembly and disengages the transmission. Check for leaks. If there are none, have a helper pump the clutch pedal while you watch that metal bar and slave for movement.

Let me know what you find or if you have other questions.

Take care,

Joe
