    can shift into 3rd while driving w/o clutch

    basically what the title says.

    I can shift in and out of third gear while I'm driving without the clutch depressed. Nothing really happens when I shift out, but when I shift it back in, there's a slight clunk.
    This only happens when I'm driving, when the car is stopped, I can't move it in or out of third.

    WTF is this?

      It's actually my second ;)

      This shouldn't be happening, but is it common?

        Its normal, at certian rpm's and speeds you can esstenially jam a transmission into gear without using a clutch this is the clunk you're hearing.

        Its a good thing to know to get yourself home if your clutch ever goes :P

          it's called rev matching

          old manuals didn't have synchros, you had to do match the RPM with the engine with the RPM of the gear you wanted to use, even with a clutch.

          it probably means your 3rd gear synchros are in great shape!

              Yea in any manual you are often able to shift through every gear with no clutch. I think it's pretty cool myself.

                good thing to hear.
                i thought i broke something expensive.

                ive heard of rev matching, but ive never known exactly what it was or how to do it

                  it all has to do with gear sycronizing

                    Good thing to be familiar with in case you ever lose your slave-cyl while on the road, it can help avoid a hefty towing fee.

                      Only really works for the slave cyl or the clutch cable. Really really bad for your started if you have to stop. I don't know if any e30s are made with starters that make you push in the clutch to start, but if you have one of those it won't work either.

                        I drove the other day without pressing the clutch in at all (except to go into first.) It's fun to practice rev matching.
