Does anyone else have this problem? I find that when I accelerate hard in first and try to get into second, it is noticebly more difficult than the other gears. It has even kicked me out of the gear a few times when I tried to put it in. I know there is a post similar to this but that was about not being able to get into second gear at all. I can get into second, it is just a little more difficult than the other gears.

I'll try to notice it next time I'm out driving...but going to work, I usually hit redline in 1st and then switch to 2nd gear with ease. My commute is 4 miles of only city miles, so I have to get my kicks somehow lol

nah i don't have an issue at all...i have only owned my tsx about 2 months but i have noticed when redlining 1st gear and then shift into 2nd the car usually bucks a little, i feel like the rpms drop sooo fast in this gear that its causing a rough shift. My old GS-R wasnt like this at all (technically they are the same car...). Giving it alittle gas between the shift (1st and 2nd gear) helps the issue though, not sure if its the same issue but you could try this to see if it helps your problem *shrugs*.

Take your time when shifting 1st to 2nd, don't slam it into 2nd. Be firm but not violent.

The main reason why it is more difficult in 1st to 2nd when compared to the other gears because the RPM drop between 1st to 2nd at redline is the largest. So the synchros have to work hard to slow the input shaft speed down from 7300rpm to 4500rpm.

Thank you for explaining that, i've always had the second gear shift problem and i try to shift slow to minimize it. That's the only thing ruining my experience with the car, it's not that big of a problem for me but other than that, everything else is great. And I haven't gone up to redline in first gear yet .

I will try this later on today and see if I am just trying to shift too fast

...i was thinking hondata and short shifter may fix this *shrugs*

aaronng

The short shifter usually makes it a little more notchy (i.e. more difficult to get into 2nd). If you want absolute acceleration, there are ways to get it into 2nd but your synchros will suffer for it.

The only time you need full acceleration anyway is on the 1/4 mile strip.

CGTSX07 - If you check out the thread i started abotu the same problem you'll find out a lot of good info. thread title is: tried search...having problems getting into 2nd over 6krpms '04 6spd . Don't know where to find the link to it but i found out some real good info on this problem and i'm in the works of a new trans with the dealer as of right now so ii'll update my thread when i found out some more stuff. Hope it helps!!

lol i like how u said violent.

CGTSX07

So i've been paying closer attention to my second gear shifts and although still a little notchy, it goes in easier when I shift slower. The only time it goes in really smooth is at low rpms. So this is normal?

CGTSX07

It seems like ur problem is a lot more severe than mine. I will def. be keeping an eye on it though.

I did not have this problem when the car was stock, even when I flatshifted to 2nd. was able to clock off a 15.201@91mph that way.

but now I have a few modifications and some more power and when I went to the track first this summer, when trying to flatshift to 2nd I just could not get it into gear, it would just grind and I couldn´t get it in, ended up loosing my 2nd (probably a busted syncro)
was able to get 2bad runs in befor breaking down and the better was 15.022@94mph.


I have a shorter 1st gear then you guys and the same 2nd but with a longer final drive so my gap between 1 and 2 is even greater

I think that a torque damper and shorter gearing will take care of the problem for good!

gearbox will be fixed under warranty and I am having a ep3 CTR flywheel(4.7kg) and 1-5gears and final drive installed when the box is out for repair. am waiting for my ingalls damper and then we´ll see how we do

aaronng

Each time you flatshift, you grind down the 2nd gear synchros. It works the first few times but eventually you lose the ability to get into 2nd.

CGTSX07

what is "flatshift"? is that basically slamming it into second from first?

Simba91102

I'm with you; been driving (and racing) a clutch for over 35 years and I don't recall hearing that before.

Shifting while leaving your foot on full throttle all the time.

CGTSX07- try bleeding the clutch and changing the fluid. I already changed the fluid a bit ago but yesterday bled the clutch and despite what a lot of people saying it won't make a diff., it def. made a noticeable diff. in my car. Even my wife noticed it and she is oblivious to everything. ha!

I have noticed this problem slightly. However, I have a bigger problem with the shift from second to third when revving second up to redline (or even close to it).

There were a lot of times when I revved second up to 6k+ and when going into third, it simply wouldn't go in and wound up grinding the gears briefly before bouncing me out. A few times later, it would simply grind the gear as it engaged, but it was barely noticeable because of how brief it was and how high the revs were.

Nowadays, the past few times I've revved up second, I've shifted a little bit slower and this hasn't happened at all.

I plan on having it looked at before the warranty is over, but for now it seems to be OK. I'm also going to drain and replace the MT fluid sometime soon.

Don't you change your fluid by bleeding the clutch? Why the two steps?

lvcurvs

My fault on the clarification. I meant i had already changed the trans fluid a bit ago and now i just did the clutch fluid.
Sorry

Ah, I see. Btw, FWIW, I have experienced hard shifting into 2nd at high rpm even when the car was new. It would grind 9 out of 10 times going into 2nd. However, slowing down the shifting will greatly reduce the problem. I later changed the MTF to GM synchromesh and the high rpm shifting problem is gone. Honda also came out with a new MTF and it's supposed to smooth out the shifting problem.

CGTSX07

I will definitely try this later on and use the GM Synchromesh JTSo recommends, sounds very promising!

There are two types. Make sure to use the one with "Friction Modified" pn: 12377916. It's a semi-synthetic fluid.

aaronng

Yeah, if your clutch bite point is in the lower half of the clutch travel, then bleeding the clutch can help.

rb1

Why would this be any different than any other fast shift? When you press down on the clutch, the transmission internals are disconnected from the engine anyway.

I'd think the main wear would be on the clutch...

aaronng

That split second where your foot if off the accelerator makes heaps of difference in terms of input shaft speed. Happened to another person here who wanted the best possible 1/4 mile time from their 2zz-ge corolla. Same synchro problems after that.

Thanks for the PN; do you know the GM applications for this one ?? Or is it
used for problem transmissions at repair time ??

Has anyone tried RedLine MTL yet ??

JTso

iTrader: (2)

The label on the bottle reads "for use in 1500 transmissions. It is highly friction modified to reduce transmission component wear".

I was searching for things to try to help the shift grind issue and came across many recommendations on this product. So, I tried it and like the result so far. I have also tried RedLine MTL on my 1998 Civic but didn't notice any difference/improvement in shifting.

CGTSX07- or anybody else. I just noticed something a bit odd this morning. The first time it happened i thought it was a fluke but then i tested for it again the past 2 days and also this morning and it's the same thing. I have to be at work at 5am so i leave my house around 4am. Woke up sat and sun. early to test for it.
Weather is usually humid and somewhat cool, around the 60's i guess.
Anyways, in these conditions, humid/cool and ONLY after start up, I have no clutch squeek, no notchy shifting and no gear is hard to get in. That's for my entire drive into work which is about a 30 minute drive on hgwy and then into city traffic.
As soon as i start the car to leave work, everything comes back. Kindof wierd to me.
Even if it's cool and humid when i leave work or any other time other then in the morning, it still squeeks and is notchy.
you guys notice this? i'll be at the dealer today around 3 so wish me luck!! ha, c'mon new tranny!!!

nbtx

This is too easy - don't go to work ...

CGTSX07

just tried testing this out this morning and didn't notice anything too different. my second seems to always be notchy when I accelerate hard in 1st. it didn't seem like it was any smoother this morning. i've been shifting slower into 2nd and that has helped.
