The most important part is the short period of time you are yanking that lever into gear. Like said already, pressing the throttle or engaging the clutch at a weird speed only wears your clutch out and does not effect the gear box, assuming you are not letting it out before the gear is engaged of course (crunch!).

Each and every time you engage that gear, you should be pulling at a smooth, firm, and even speed. Pay attention how hard it is resisting going into gear. If it is too hard to pull in, you are doing something wrong. Some gearboxes are even temperamental and hate going to slow! Consistency is the key, with a firm but gentle hand.

"Exploding gears" from the previous owner may have also been from abuse while the gear is already engaged. Things to avoid are violent on-off-on-off throttle snaps over and over, or dumping the clutch way to fast. If your style of clutch engagement involves releasing to the halfway point fast and then going slow, that could be considered too fast.

Man, i wish i would have read this yesterday. I have been driving a stick for almost 14 years. I have driven a few AWD cars but never really aggressive. I have been breaking my car in slowly so yesterday i figured i try a quick 1-2 shift. Well when i did it i shifted at about 6k and the car just bogged down and the traction control came on. i was like wtf. So my bright idea was to try it again and take the traction control off. Well the 1-2 shift was accompanied by a large bang that freaked me out ( i assume it was the rear diff hitting the crossmember as said in this thread).
This give me some sound advice on shifting an awd car.

Quick question i also changed my shift knob to a cobb shift knob. It made the shiifter height shorter. It seems it takes a bit more force to go into 2nd and 4th now ( I assume cause its shorter). Just want to make sure i didnt break anything.

I finally got through the break-in on my '11 wrx and wanted to have a little fun yesterday and this happened to me. It didn't feel like I broke traction so I was wondering wth was going on. I am guessing this is a safety feature to protect the driveline? I guess the best option for quick shifting would be to turn traction control off and then slip the clutch a little. My previous car was an '05 STi so I never had this problem.

The clutch dump valve is the only feature that I'm aware of that helps protect the driveline. Both of your descriptions are a bit to vague to tell if it is affecting you. It is not related to any clunking or traction control though.

If you are "quick shifting" by shifting clutchless, then yes, you are highly recommended to use the clutch at all times in the WRX. You may be able to get away with it in an STI, but the WRX trans is not as nice.

In my case, I had the car in 1st at WOT and performed a "quick" shift at redline into 2nd using the clutch, no slipping just dropped it. The engine bogged down and the traction control light lit up. The engine then regained power and started accelerating again. It felt as though the car braked on purpose to prevent a hard shift from happening?

I don't plan on doing this very often, but I could see it affecting time slips at a drag strip by quite a bit. Just curious if my car is supposed to do this as part of the T/C system or if I should get it checked out.

btw, is this the thread to discuss this in (FAQ thread) or should I start a separate thread about it?

I've been told that the new WRX models have all open diffs, front and rear. One local with a new one takes it to the drag strips, and when launching, one of the fronts or rears lights up. If you left traction control on and this happens, of course it will try to cut in.

Yes, you should take a look around for another thread that discusses this, or make a new one with your question if it doesn't exist. I'm sure there's someone else that knows more about that subject than I.

Im new to this forum and kinda new to the subaru world. Worked on them but never owned on till now. Treated myself to 2011 wrb wrx. Now to the point for work I drive a big international flatbed with a 6spd and sometines the 10spd. Most of the time I dont usr the clutch. I "blurlp" in and outta gears. So the question is that bad or would be bad for my new wrx. Any input would be great.

Sorry for the the whole noob long message.

I've seen many 5MT Subie gear boxes turn to crap with killed syncros. Shifting without the clutch is not recommended, they are not industrial strength like you will find in a truck. Lighter weight, faster speed, and less effort are what they are designed for.

The WRX 5MT is more of a pedestrian box, but a bit beefier (extra weight) on the gears to keep them from blowing on jolts. You can't hustle it as fast as a close ratio 6MT up or down a gear, and I recommend double clutching any time you skip a gear or more, up or down.

You don't have to always double clutch. If you can get in the habit of doing it on major skipping up and down, you'll drastically increase how smooth your syncros are at over 100k miles. Now that I'm in the habit of doing it, I usually do it almost every time without even thinking about it.

The exception to this is: for the 5MT, always always double clutch when downshifting into first gear while the car is rolling. If you read carefully in your manual (at least mine says so), it says to never put the car into 1st gear while the car is in motion, you are supposed to stop completely before selecting first gear. You actually can safely stick it into 1st gear all the way up to the redline speed (around 25mph) if you properly double clutch. Don't try this unless you are very comfortable doing it

First off...
Excellent write-up !!!
Now here's my .02$ :

Rev-matching the down-shift into 1st = essential !!!
Some civic clutches have been known to EXPLODE when dumping the clutch (no comment please-it's just an example).

The loud THUNK u hear when power shifting ur new WRX = most probably the center diff locking up (this is normal)

You should NEVER try to DRIVE ur car with the track-control on...it's designed to slow u down. Traction control is for girls!!!

Double clutching : I have nothing bad to say about this technique. It is very useful when you're driving slow & want to drive smooth. Just don't do it @ the red-line!

Skipping gears (ie: 2nd - 4th): DON'T DO IT !!!
Very bad for the synchros. It really doesn't take much time to go 2--3--4...you don't even have to let off the clutch, just the fact you touched 3rd slows the main shaft down enough to avoid severe damage. If you going from 2nd to cruising you have time to touch 3rd.

Once again, Awsome thread !!!
Keep'em coming DUDE

Anyone with an '11 wrx notice that it grindings going into gear when doing a shift at around 6k rpm? 5k doesn't seem to do it, but in the 2 or 3 times I've done it since owning the car, it has grinded every time I've tried to shift. I've driven many high end manual sports cars before and this has never happened. Your torque starts dropping off after 5k rpm anyway so shifting at 6k shouldn't be normal practice when driving aggressively, but I am curious as to why there is grinding regardless...

Hello,

I just picked up an 02 wrx wagon with 153,xxx miles. I've been driving it for about a whole day now, and there is one item I'm a bit concerned with.
When accelerating, between 2-3000 rpms, the car feels as though it kind of shudders or lurches almost. I've been told it's probably turbo lag (this is my first turboed car) and it's nothing to worry about. However I would still like some second opinions if you will. I know how to drive manual, but this is my first full time awd manual driving.

Is there a noise coming from the tranny (like below you) or is it more of a engine stutter (like running out of gas or stalling) sound?

I had an 03 Wagon and the trans had issues from the get-go... Perhaps the young salesman who sold it to me had been cranking on it! Eventually, my synchros in 1st, 2nd, and I think 3rd were shot. They said I had a bent clutch fork as well. In the end, and thankfully under warranty, they replaced the first 3 gears, all synchros, and clutch fork. It was pretty good for a long time after that, but was starting to show problems in the same areas - can't shift to 1st at ANY speed and 2nd is a rough engage.

Now, some would say it was driver error, but I've been driving stick forever and my current 02 that's Sti'd and upgraded putting out at least 350HP, has clutch and gears that are doing great, both up and down shifts are smooth as silk, and I can even shift into first at at least 15MPH. I believe I have the RA gearset though, straight cut gears = more noise, but more power holding. Either way, I could frag this tranny up real good with bad shifting, especially with all the TQ you get under boost on an STi.

So, my point is, those early tranny's had issues, a stock 02 does need some significant RPM's (think close to 3K) to have enough power for upshifts, especially if you are accelerating, so you could have either issue depending on the sound you're getting.

Also, I have to note that UncleScotty's trans fluid "cocktail" is awesome! I put that in my tranny that was starting to get rough and it totally saved it. Would have kept getting worse (grinding = wear = more grinding, etc.), I am 100% sure.

That shudder is probably the infamous hesitation issue. Some people have them, others don't. Check the newbies forum for more great info
