i have a 97 gsx and when i rev it at high rpms it grinds going into 2nd. but its fine if you dont have the rpms up? whats the issue?

you could try this test and make sure your clutch is not grabbing. Could have already done its damage to your syncros' though.

So you are saying that you are doing high RPM shifts? As ETS posted up, make sure that you have your master cylinder adjusted properly to allow the furthest actuation of the slave cylinder by following the instructions in the video.

It could just be possible that your syncros are wearing out. What trans fluid are you using?

A good rule of thumb is:

If the trans blocks you from a gear, the trans synchro is working but can't synchronize due to a clutch problem. It is warning you and if you keep forcing it, the synchro will burn up and be damaged so now you need both a trans rebuild and a new clutch.

If the trans grinds, the synchro is done. You need a new clutch and trans.

Below is a copy of our paperwork we include with our rebuilds for the driver. Keeping an eye on things and becoming aware of a problem quickly can save you a lot of money in trans repairs. We know you don't have our trans now, but this might help so another isn't damaged:


Transmission Care and Tips
Thank-you for choosing Jacks Transmissions for your transmission rebuild! We take great care to assure proper operation of the unit before it leaves our facility. We pride ourselves in our ability to modify the synchro slider timing to allow for the fastest and most accurate synchronization possible. In other words, your transmission should shift better than any other unit you have felt before! Though there is a huge amount of time spent on your transmission to assure superior synchro operation, this does not mean they can never be damaged or feel notchy if something else is wrong. The #1 reason for transmission synchro failure is due to clutch issues. Please read below for tips on how to recognize a clutch problem before it ruins your Trans. Becoming aware of clutch problems could save you thousands of dollars in transmission repairs in the future.
1) The transmission should never feel notchy or block you from a gear while shifting (some people call it 'lockout'). If this happens, NEVER force the trans into gear or the synchro will be ruined! This applies at any engine RPM. If it shifts smooth at low RPM, but it blocks you at high RPM, there is a clutch problem and it must be fixed immediately! When a trans blocks you from a gear, you are experiencing what we call 'clutch drag'. This means the clutch is not letting go of the disk fully and dragging on the assembly. An adjustment might need to be made, or the clutch could be excessively warped at the pressure plate. If the Trans won't go into gear at all, the clutch is severely warped or broken, STOP and do not drive the car or transmission damage will occur!
2) When launching, do not ride the clutch. Riding the clutch is when someone stays in the clutch 'friction zone' too long and overheats the unit. When a clutch is in the friction zone, it is using friction to operate and move the car forward. If you stay in the friction zone too long, the unit will build up enough heat to damage the assembly. This can quickly warp the pressure plate and cause clutch drag, which will then cause the Trans to feel notchy when shifting.
When you launch, just give the clutch smooth and quick engagement without sitting in the friction zone. You want to stay out of the friction zone to prevent overheating, but you do not want to dump and shock the clutch either as that will break other parts. Staying in between the two can be tricky, but if you find yourself riding the clutch, let off the gas immediately and stop. Let the assembly cool for at least 15 minutes, and then try again. Do not launch over and over again, as even smooth and proper launching repeatedly will overheat the unit if not enough time is taken to allow cooling.
3) Do not shock load the clutch. Shock loading is when the driver lets the clutch go too harshly, and quickly, and allows the clutch to engage so violently that it puts a shock through the system. Shock loading while launching, or shifting, can pop the rivets of a sprung hub clutch disk and cause the clutch to drag, which will kill the transmission. Shock loading can also break Tran's gears, CV shafts, and other drive-train components. Shock loading doesn't make you any faster and is very harmful to many parts.
4) Become familiar with the feel of your clutch and transmission. If at any time the clutch feels different, or the Trans doesn't shift smoothly, something is wrong. STOP and do not continue driving the car. Check for clutch drag, check the hydraulic system, or worst case, pull the clutch back out and check it too. The feel of a clutch and Trans should never change, if it does, something is wrong. Becoming familiar and aware of the feel of your clutch and transmission will help prevent costly repairs in the future. Clutches are a device that uses friction to operate, so it will warp, and it will wear out in time. It's when the driver can notice a change, and not ignore it, that saves your transmission! Having to rebuild your transmission every time the clutch wears out, or breaks, is something that should never have to be done.

someone said to check the adjustment in the car?

I did the clutch drag test. i got on flat ground put it in first gear and reved it to 7000 rpm and the car moved.. I didn't have the chance to do as the video said i will tomorrow and hopefully it turns out well..
