High RPM Shifting problem

[d_breezer13]

Ok so at high rpms between 5 and 7k its hard to shift from 1st to 2nd and 2nd to 3rd. I have to wiggle it and force it in almost. Its almost if it dies down to 4k to 45k it will go in to gear. So if anyone has an idea whats wrong? I have just installed a ACT 2900 Clutch and new throw out bearing. Also it grabs close to the floor. And when im going all out and i shift before 5k it is okay. It will go in fine. I dont understand whats happening. So if you have a suggestion or any ideas please help thanks!

Your clutch is dragging.

Put the car in gear on a nice flat surface, rev it to 7k RPM. Did it move forward on you?

Have you inspected the clutch pedal assembly? The smallest amount of play in the pedal will make your car not be able to disengage fully and the pedal will act like its on the floor.

Make sure all your transmission bolts are tight, and don't forget about the small M8 bolt going thru the transmission and into the block. Did you install the new dowel pins that ACT provides with their clutches?

So if it moves forward its dragging?

yes thats right

Okay i will go try that tomorrow. I will get back on here if it doesnt do it.

Well just went outside and it didnt move at all. So now what could this be? I have a ebay shifter?

i have the same problem. except its only at high rpm in 2nd and it grinds if i have WOT and shit around 5k its find any higher and it grinds and wont shift. i thought it might just be the syncro

Mine doesnt grind at all! Thats why its weird to me. And it started after my shifter spring broke in my ebay shifter. Then i got my clutch put in and now it just doesnt want to go in.

LMao the spring broke in your shifter. Don't use ebay 'performance' parts unless they are genuine, in my opinion, bros

Even then, be sure to research parts extensively before you buy. Even the leading performance aftermarket parts have issues. There's usually one brand that really stands out above the rest and is race proven. Otherwise, genuine OEM would be your best bet - nothing is more thoroughly tested.

Yes i did. And yes i know! I regretted it once i bought it. It worked fine then got a lot of side to side play. then found out it was the spring then now its fine. But now its doing what its doing now.

You don't think it's related to the shifter, or you put the OEM back in?

Well, could be your 5 speed transmission. What kind of miles on it? When's the last time you changed the gear oil, and what kind did you use?

I think it is! But I havnt put the OEM back in. I might do that to see if it fixes it.
