I have asked you guys about the difficulty I was having with putting it in 1st gear while at some occasions it is easy. Lubricated ever, changed the oil, still the same, also there was a noise I wasn't sure of turned out when you press the clutch it goes away so I guess the throw out bearing is going out because the noise is down by the transmission only when clutch is depressed. Also the clutch pedal is held for 20-30 seconds the gear is hard to come out of first gear as if the bearing is baked on the clutch. How hard is it to replace the throw out bearing on this one?

It is not that complicated but the transmission needs to come out which is the complicated part. I attached the process on replacing the release bearing for this the 02Q transmission which is most likely what this one has.

The O2E transmission has a direct shift gearbox which is less common.

Due to you going through all this, I would suggest replacing everything while you are in there like the clutch, bearings, slave, and flywheel if needed.

Let me know what questions you have. Thanks

What is a direct shift gearbox, and could a bad throw out bearing cause gears to be difficult to go in?

The most common failure of a bearing is squeaking when you press the clutch in.

Sorry I wasn't more clear. The direct shift gearbox is basically a manual transmission that is shifted by the computer. So it operates as an automatic but the components are of a manual transmission.

The likely cause of the shifting issue you are experiencing is a slave cylinder that is leaking internally and not allowing the clutch to fully disengage. This makes it hard to change gears and first is always the worst.

I suspect you just need to replace the clutch and other components while you are in there.

But this is not a DSG, it's a regular manual transmission 6 speed with a clutch pedal. I thought DSG is where you operate it like the M3s and M5 BMW's as well as some automatics with paddle shifters.

Correct. I am sorry I am not being clear. You do not have the DSG. I should not have even mentioned it. You have a standard clutch with pedal. The DSG doesn't even have a throw out bearing. They have needle bearings so it is not related to what you have.

Your issue is just a worn out clutch. As I said, it is most likely a slave cylinder that is leaking internally not allowing the clutch to fully disengage. However, once you go in you will want to replace the entire assembly so you don't have to go back in for something else.
