Listen To Me!!!!!
The facts are these 5MT and 6MT transmissions found in the WRX can be rather rough around the edges. They can be resistant to get into 1st and they can feel crunchy and/or slight grindy getting into 2nd. That's just the nature of them. There are a couple things you can do to improve these issues: 1) If the tranny feels resistant going into first, do the following: select neutral, clutch out, release the brakes, clutch in, apply the brakes, try and select 1st. This sometimes helps. 2) On the 1-2 shift, get the rpms above 3500 before shifting. 3) Shift the 1-2 fairly slowly, especially when the tranny is cold. 4) Heavy weighted ball shift knob. BY FAR THE BEST way to improve shift feel. I can't stress this enough. I've had my 2012 WRX for 4 years and it's recently been returned to stock to sell. The car currently has the factory STS still installed and it formerly had a 1lb LatheWorks shift knob (over twice as heavy as the stock knob) and the Kartboy from shifter bushings. After driving around without the shifter bushings, I came to the conclusion it really didn't improve shifting that much overall. The shift knob? Holy crap. Massive difference. The knob makes the shifting feel way beefier, it's easier to get into gear, substantially cuts down on vibration, and reduces a lot of ugly feeling on the 1-2 shift. I put the heavy shift knob back on for the time being until I sell the car. Before doing anything else, I strongly recommend getting a heavy shift knob. Also I strongly recommend not getting a STS that reduces the lever height. Reduced lever height means less mechanical leverage, thus even more resistance getting into gears. Don't do it.

I will vouch for the heavier shift knob. Gave it a much better feel. Went with the Raceseng Ashiko.

I test drove a 2016 base with the Factory STS, and noticed the same issues with 1st and 2nd, as the OP.
Since the Factory STS are "Port Installed" could it be that the port installers aren't taking the time to adjust the shifter after installation? |

also might want to try an upgraded transmission mount. I just got the "sti" version (not "group N" mount) so will install it soon but I heard it helps with the feel when shifting.

It was probably that horrid shift carrier bushing or whatever it is called that is in them. I swear mine feel like it is made out of a twizzler sometimes when I shift it. I need to change that garbage out but I am being cheap and lazy (plus I am debating on selling the car anyway).

2016 WRX Transmission Woes
Hello, first time poster, long time lurker.
I'm glad that I found this thread. I was beginning to worry that my car was somehow defective, but I see that everyone is running into the same transmission issues. I own a 2016 WRX Limited with 6k miles on it currently. I love everything about the car except the 1st/2nd gear. A week or two after I got the vehicle I installed a Perrin shift stop to eliminate my occasional trouble shifting into 2nd gear. For the most part this fixed that issue. As we all know, neutral extends further left than the gates for 1st and 2nd. If you're not careful while shifting into 2nd you can get "caught" in neutral. If you're careful while positioning the shift stop you can eliminate this scenario. Since installing I haven't run into that situation since. Bravo, I have effectively spent $50 eliminating a design flaw. Next flaw: at 4k miles I have forward/backwards play on the shifter (maybe 1cm at the top of the stick?). I imagine this is caused by a worn out bushing somewhere in the shifter linkage. I've purchased a Perrin brass shifter bushing in hopes that this will solve that problem, but I'm not certain. When it warms up I'll get to install it. Now, these two things are annoying, yes, but I was able to fix them. The most annoying thing I've found is downshifting into 1st when coming up to a stop sign. Yes, we all know that a manual transmission car should not let you shift into 1st while going 30mph. But what about 5mph or a complete stop though? I have on numerous occasions come to a complete stop, wanted to shift into 1st and couldn't. The only remedy was releasing the clutch slightly in neutral and trying again. I don't know that much about the inner workings of the transmission, but I think that the synchro's are supposed to take care of this automatically? Sounds like another design flaw, although this time I don't think I can remedy it. Maybe, just maybe, changing out the transmission fluid will help. Dunno though. Quote:

Sounds about the same as the 5 speed they put in the WRX for over a decade.
Subaru in general has horrible 1st/2nd gears in both N/A and turbo applications. Additionally reverse often gives you some serious problems in the cold. I had more problems getting into reverse than anything in my 03 WRX. In my Mom's '11 Impreza is the same. And same in my 95 Legacy as well. C/N: if you really expected Subaru to put a good transmission in anything but the STi you got played. |

Alright...no one take the following as a recommendation of any sort, just something to add to the conversation.
Honda 6-speeds had an issue with the 3rd gear synchro for a period of time. My Accord had it. It had resistance going into 3rd as you described, and I even grinded 3rd a few times. I had to very carefully shift to third and I half-winced every time. This is a known and VERY ubiquitous issue on the Accord 6-speeds and Acura TL 6-speeds. The absolute fix was GM Synchromesh fluid. It has been PERFECT for the last 3 months. Not even a hint of a misshift. Some people have used GM Synchromesh in Subarus as well (I believe Uncle Scotty recommended it?) with similar results, but I DO NOT know whether or not it will work well in the new WRX 6-speed. I'm just throwing it out there as an option to look into because...like i said, it was like a magic ****ing potion for my Honda. |

http://www.grimmspeed.com/1-transmission-cocktail-mix/ Honestly changing the fluid doesn't help thaaaaaaaaaaaaaaat much. Change transmission fluid only if you're having synchro issues otherwise it's going to feel exactly the same... |

Maybe I'm mistaken but it seems like the OP is experiencing synchro issues. Now, whether they would be solved with a fluid change (or if it's just a ****ty design) is unknown...and that's why I'm only mentioning Synchromesh not recommending it.

What's wrong with Extra-S 75W-90? They sell it in small bottles now so you don't have to buy a 5 gallon drum. http://www.fastwrx.com/products/suba...ance-gear-lube |

I thought the gearbox absolutely stunk when I first got my car. I was looking at any fix out there at the time, from Perrin to Boomba, Kartboy, etc. I now have 20,000 mi. on the car, and never bought anything for the shifter. I can honestly say it has gotten better with use. (STI short throw). I guarantee I haven't lowered my expectations to compensate. I do have an old habit from my Land Rover days of almost always shifting from second to first when at a stop. I hardly ever go into first from neutral. Maybe it helps, perhaps I'm just loco.

The 2015-16 6-speed is factory-filled with Extra-MT which is a different fluid from Extra-S. I would not recommend changing fluids on these just yet, I know I'm not touching mine.
You're not going to get the same feel with a cable shifter as with the old linkage. I still have my '02 and there is quite a difference between the two, that's just how it is. The Kartboy short-throw plate did help in the '15 but this is not a smooth-shifting box. |

But regardless, like you said, I don't see any reason not to go with what Subaru fills it with, especially while you still have a warranty. |

I think people using the cocktail were using it as a band-aid for an already wrecked transmission hence the "damage". Besides, I'm not advocating it, in fact I'd advocate to just leave the factory fill until you need to replace your clutch or something. That said, Extra-S is a good option. Really doubt it's going to change your shifting feel. Just get the Kartboy bearing and maybe even the short throw shifter plate. I have no issues getting mine in gear. |

No it's not. It's based off the diesel 6 speed. That's probably why the gears are **** for 1/2 Quote:
Hey look man, just because you can count to 6 doesn't make you right. The "6 speed" they are referring to is the proper STi 6 speed, as it has fluid pumps and different metal alloys in it. There was some concern that the bits in the anti shock fluid would contaminate the pumps. Not related to this conversation about the WRX 6 speed one bit. In fact, I ran Motul 300 in my 2015 wrx with a quart of redline heavy weight anti shock and it was beautiful. No more of that "thud thud chckck" noise when shifting into second. |

This is not the first time I'm hearing that this gearbox is based off the diesel gearbox. I don't see a part number and I can't match one to the gear ratios this one has so it's definitely unique for the 2015 WRX. They just mixed and matched gears from the other transmissions (except the STI). |

I haven't dug that far. On the t56 (tremec) there were multi piece synchros for the first few gears. I guess it was to assist in synchronizing. I've actually got an assembly as a paperweight at work lol. Could definitely be a hodgepodge. Just sucks that it was so awful. My v7 JDM STi trans was crafted by ye gods. |

I ran some bull**** Auto Zone trans fluid for a while and my transmission was fine too. I guess that proves that you can put anything in a Subaru and it will be fine, huh? |

The new fluids will be going on Saturday. Call me crazy, but I'm dumping Uncle Scotty's cocktail in that crunchbox.... If I screw something up (HIGHLY doubt it) then its on me and I will deal with it. On the other hand, maybe its the magic snake oil the 2015/16 WRX guys have been dreaming of... |

Like I said, I did mine at 11k miles and the magnetic plug was covered in junk. It made a noticeable difference. Valvoline synthetic 75/;90 2nd is still tight, but not like it was, and that has been lately with the northeast weather we have now. So we're talking lows in the teens and single digits. Within 1 mile it works near perfect. Basically my first 1-2 shift is tight, then it's good. |
