Shifting smoothly

Rev matching doesn't do shit for a rolling first-gear downshift.

I have LITERALLY no idea what you're on about. I rev match into 1st and it works fine. I don't have to double clutch at all...

Here, I even made a video for you where I simply rev-match into 1st at 15 and 20 MPH smoothly and without any drama.

I don't get it either. I've never had a problem dropping to first at the proper revs either. I think there's a couple people in this thread who aren't sure how a clutch works. It's not like it engages more on the second pump.

I am with you. I have never once double clutched this car for any gear. Never found a need to.


Dom would scold me I am sure!

There is nothing wrong with double clutching and some may prefer it I just never found a need. Now my old Talon TSI was a different creature completely. Double clutched so much my left leg was huge!

I only double clutch when the music is just right and I want to get my Fred Astaire on.

In the sequence of events of your downshift, when do you blip the throttle?

If your clutch is disengaged and you blip the throttle while you're in neutral, it does nothing to help you get into gear. If you've already downshifted into first and you blip the throttle before you engage the clutch, sure, that's a legitimate rev match.

I cannot shift mine into first above maybe 7 MPH without double clutching. I've driven some friends' cars which are very easy to downshift into first. There is quite a bit of variation in the first gear limit. I have a theory that some units were assembled without the limit ball but it's probably bullshit.

Sequence of events:

Push clutch in.
Blip throttle while moving shifter from 2nd to 1st.
Release clutch.

I am not double clutching. The clutch gets pressed exactly once. Maybe your car is borked, lol.

It is an engineered feature which prevents shifting into first if the speed difference between the input and output sides is not close enough.

Or ours are!

I have participated with Ultra in many of these hard shift threads and I have never experienced any of the things people talk about. No gear lock outs, no hard shift to second when cold, down shift easily to first and not a single grind (that wasn't self imposed that is). As much as I would love to attribute all this to my highly skilled, above average , stupendous, ultimate highway warrior driving skills I just don't believe that (I tried to take off in third today and boy does clutch smell bad when heated). What I do believe is that there is a huge range of quality in these transmissions with some at a much better build level than others. I have never really paid much attention to the year of the cars where people had the most complaints but would not be at all surprised to find they are mostly 13s and early 14s.

Okay. Sooooo if you rev match properly, you will minimize the speed differential...

What am I missing here? Double clutching serves to bring your transmission input shaft up to the speed of your engine, but synchros do that for you in modern transmissions. Blip the throttle so that the engine speed matches the speed you are traveling in relation to first and the shifter will eagerly snap into 1st gear.

That's an interesting theory. What years are yours? Mines a 2015.

EDIT: Just realized our profile info to the left states this information, lol.

More of a hypothesis than an actual theory and based purely upon anecdotal evidence so should be taken with a grain of salt.

Your first statement is incorrect. Revving the engine does nothing if the clutch is disengaged. That's my whole point.

The first gear limit ball reacts against the first gear synchro and keeps it from making contact. It's there not only to keep you from killing yourself but also to keep you from killing the synchro.

I've looked at the exploded view. I can't really make sense of exactly how it works but it's real.
