Is it the slave cylinder or what?

Hi,

Do you mean with the engine off? If it shifts only with the engine off, then chances are it's either the slave or the clutch master cylinder. The clutch master cylinder is actually supplied brake fluid from the brake master cylinder. Check to make sure there are no issues there. Confirm there are no leaks at any point.

There are no specific tests for determining which is the issue other than looking for leaks. Often times, I will simply disconnect the slave and see if the clutch master cylinder produces pressure when the clutch is depressed. If it doesn't it needs replaced. If it does, then the slave is the most likely problem.

If you need directions for replacement of either, let me know.

Take care,

Joe

Oh, that is totally different than I understood it. So in essence, you have no gears. First, confirm that both front axles are full engaged. I have seen them move enough that they were no longer attached in transmission.

If the axles are full engaged, something has either broken or is stuck in the release mode. Although it could be a slave that has jammed, it wouldn't be the clutch MC.

First, confirm there is no play in the axles. Then, you will need to remove the slave to confirm it isn't stuck in the actuated position.

Also, let me know if you place the trans in gear with the engine off if there is any resistance stopping the vehicle from moving as well as if there is any noise when you have the engine running and press and release the clutch.

If there is no resistance, I suspect it is an axle issue. However, it could be the slave has jammed in the release position. So, if the axles look good, remove the slave for inspection.

I will check in the morning. Do you have a diagram for the alternator wiring harness and does it need to be hooked up for the engine to start and run for a brief second? I have a second 2000 Beetle. Identical to other. Had to install the complete air intake system and the fuse box on battery was missing. Hope I hooked it up properly. All the lights work and the car turns over but hasn't started up. If it don't then I'll be changing out the engines. But the one with the alternator and fuse box is a better car. But not sure how to hook up alternator harness. And would like to see how the fuse box on battery is hooked up from factory. To see if I did it right. But the car turns over but hasn't started up. Diagrams for both would be nice. If you have it. Thank you for replying do need your help.

Hi,

I attached a picture (pic 1) of the complete charging system schematic. As far as the fuse box on the battery, see pic 2. That's the only one I have.

I hope this helps.

Let me know.

Hey I am back. Its been a rough one. Okay, the transmission did shift into reverse. I felt it go in gear. Now does the forward gears use a different cable to shift with. Because it might feel like it going in gear, it feels really loose. Like maybe a cable is broke possibly. I am going to take the lower mileage engine and put it in my other 2000 Beetle. Because the engine in it runs but has a pretty good water leak on the side closest to firewall. I'm not sure but I think its the head gasket. Because its coming from way up in the back above that water line or heater hose. I haven't pin pointed it. And to do an engine swap. Can I take the front clip off instead of going out the bottom. I don't have the tools to lift the body up enough to get engine out. Not even a good tree to help with a chain hoist. If I can get the engine out by taken the front clip, I can get it done.

Hi,

There are two cables. Check to see if both are moving on the transmission when shifting through the gears.

As far as the coolant leak, is it on the driver's side? It is very common for the coolant temperature sensor to leak. It is not threaded into place, but rather it is clipped in and an O-ring is what seals it. I can't tell you how many I've replaced.

As far as engine removal, I have only ever removed them through the top with a hoist. I don't think you can remove the rad support. I believe they are welded on this year.

Let me know.

Joe

Well the leak is up in the back, close to the head. On firewall side. And it is closer to the driver side. And where is the coolant temperature sensor located? And I will check it out. That would be nice to know.

Hi,

I attached a pic below. I circled the item I'm referring to. Note that it mounts to the engine and there are other water hoses that go to it. The hoses under the housing commonly never get replaced and end up leaking. Also, note that the coolant temperature sensor is held in with a clip. If you ever replace it, replace the entire plastic housing because they rarely seal and will drive you crazy. LOL

Take care and let me know if you need anything.
