Damn, after when I bought my 04 WRX I've took it for a spin and I've notice shifting fast into gear 4 grind. What wrong with it and what should I do. I there a recall for this? HELP!!!!
Alright, start with the basics. When is the last time the transmission oil was changed? If you don't know, it is the first place you can start and it may help with the grind. How fast are you shifting? We also need more information, how many miles are on the car? Any mods? If 4 quarts of Extra-S or whatever other gear lube you go with don't solve the problem, then you're looking at synchro replacements, which means a rebuilt transmission.
i had a grind going into 4th and periodicaly it wouldn't go into 2nd with my old 5speed. i loaded it up with extra s and put int about a half a cup of marvel mystery oil. Never had a problem with it not wanting to go into 2nd or 4th gear grinding again.
I had the same thing happening on my 02 wrx 5spd. I ended up putting in an uncle scotty's tranny cocktail mix and i haven't had the problem for over 12k. Mike
There is a pretty good thread about it on Nasioc, I was a believer but I'm not recommending it anymore. I've seen enough evidence to the contrary to stop running it in my own car or to not recommend it over Extra-S. YMMV.
Charge for what? A transmission rebuild or a fluid change? We don't even know what the problem is, there are a few reasons that it could be making noise. Try changing the fluid first and see if that solves it.
The dealer will charge about 1100 bucks for the labor. I don't know how much the parts will run you. I just had my 5th gear replaced, but it was under warranty.
^^ +1 for not shifting fast. I've found that it really helps sometimes to wait about a half a second with the shifter at the entrance to the gear notch. I think it helps the syncro catch up. This doesn't always help me with 1st gear, though. Sometimes I get a random grinding in 1st after I've been sitting for a while at a stop light. No idea what causes this, and it pisses me off. I'm thinking of trying Extra-S.
That's nothing new with the 5spd; sooner or later they will blow. My 2 gear went out on me not long ago and both of my cousins' bugeye 4th gears are grinding too. The best thing to do is invest in ppg gears or get a 6spd to save you the trouble in the long run.
06+ WRX's got twin cone 1st gear syncros which alleviate the grind issue. You can also get into 1st while going 30mph. My last 5mt wouldn't engage over 5mph.
This is not true. As with all things automotive, it fails as quickly as you abuse/neglect it. I had an 02 (weakest of 5 speed) for 3 years that saw autocross, road racing, and drag racing. The original transmission shifts fine in all gears with approximately 260 whp. If you take care of it, it will last you. If you Chet it, it'll blow hard and fast.
Try some different fluid, dont shift fast. My 5mt, designed to deal with 135chp has held up to 200 whp for over 200k miles, its all in how you treat your equipment.
Seconded. If you're not shifting like a hamfisted racer wannabe or trying to run insane amounts of power through it it'll work fine. It's not the ideal transmission, but it's not the glass box that it's made out to be.
+another on the 5-speeds lasting just fine if you don't Chet them. My WRX had over 400 ft lbs of torque and its lasting just fine. I know that Subarus don't shift like Hondas, so I don't try to make them.
hmmm me too, i think it's just a suby thing, the shift pounds are heavier, not like hondas, where you could use a finger or two to shift. i used to do lazy shifts in my honda, then when i got my 02 suby, i sometimes grind in 3rd or 4th shifting fast, it is like you almost have to time it right and throw it hard, grinds sometimes in reverse too, but that is only if the car is moving, have to fully stop, before shifting in reverse. suby have a totally different gear set, if you're only used to driving other manual. this is with a stage 1 clutchmaster, and royal purple tranny fluid. correct me if i'm wrong on any of this. plus suby will not let you go into 1st gear if the car is moving, you'll have to lag on 2nd gear, stage 1 finally alowed me to go into 1st gear if moving .0001 mph, before i couldn't.
That's abusing the transmission. That's also abuse, reverse gears rarely have synchros. If you're moving forward, I would expect it to grind when you put it in reverse. The car's moving the wrong way. I used to shift into first with my car rolling about 10 mph when it was warmed up all the way. You need to know how to drive a manual well to make the WRX transmission play the way you want. It's not a Honda where you can abuse it like Tina Turner and it keeps coming back for more. The general public really has no idea how unusually stout Honda transmissions are made, so in reality it's not a fair comparison to other transmissions from other makers. This is especially true when you're going from a FWD platform that spins maybe 2 wheels if you have LSD to an AWD platform. You can't slam the gears around like a ham-fisted mullet-racer and expect it to put up with that kind of abuse for long. One could say that the Impreza helps teach people how to really drive if they're willing to learn.
thanks alot bro, you mean it could be a tranny thing, cause it was doing this with stock, when i first boughted 3yrs ago, plus my bro n law 1st 2.5rs brand new was the same thing, and his wrc he just bought does the same thing, it'll not go into 1st with car in FORWARD motion position, and car is always moving BACKWARDS when implying rev. 1st car since 16 was a manual, went through 5 cars, 89 toyota celica, 89 toyota truck, 92 honda si hatch, 93 honda ex, 93 outback, all manual, now the 02 wrx. outback was easier to shift, but you could really feel the shift pound difference. dad drove manuals too, so manual is in my blood, but i learned alot about the shift difference in suby, when i picked up subaru performance book online at perrin. it's not detailed, but the experts rally drivers does stated that those stuff i mentioned are there for a reason, like not being able to shift to 1st when car in motion, or 10mph, is why suby shift box are considered one of the best, strongest. i'm talking about jsut stock. like other post here, that claims to eliminate that grinding or bypass that 1st gear problem by putting on aftermrkt parts. we're not talking about aftermrkt parts. Not trying to be an ass, but just putting out what i know, maybe i gotta get out of that fast honda shifting syndrom. Oh yeah, plus this car is so much stronger and faster, that you have to shift fast, especially in 1st and 2nd gear, 3 secs and your already redline, then 3rd give you a stronger hold, i could do 90 -92ish in 3rd, my other MANUALS gave you about 4-5 secs in 1st, so slow you have to petal to the metal. 02 wrx, i could go 3/4 down on the petal, and you'll hear voom 1-2 sec, redline swoosh, 2nd gear vooom 1-3sec, redline swoosh, 3rd gear vooom 9-10sec redline swoosh. Something like that, i'm not an expert, but know enough at 14yrs of driving only manuals. plus all my other manuals, i could always drift backwards and shift into 1st, and move forward and shift into rev. maybe because of weak tranny on them?
