My engine build was just finished. My transmission was working fine before I was able to take it to 8600 rpms with no problems shifting. When I did the rebuild I purchased a new Competition Stage 5 4 puck sprung, competition 12 pound flywheel, new Throw out bearing, pilot bearing, and mfactory shifter bushings. Only thing changed in the trans was a bad input shaft bearing. I'm running Honda MTF.

When my trans was apart I was told 3rd and 5th had a little bit of damage, but that my 2nd and 4th were perfectly fine.

Now my problem is when I try to shift into 2nd or 3rd at 8800 rpms it's blocking me out. I had no issues before going to 8600. Yes, I'm making power up to 8800 rpms. Even shifting at 8500 won't let me in, and 8000 is very rough to get in.

Driving normal I have no issues. Anything below like 7500 goes in like butter. I haven't tried shifting into 4th or 5th at 8800 mainly because 3-4 is going to be over 90 mph and 4-5 is going to be over 120mph according to mfactory.

I don't want to spend $100s of dollars rebuilding the trans if that isn't the issue. I was told it could also possibly be the clutch.

Does anybody have any ideas what could be wrong here..?

 

what clutch you using my act locks out anything over 7600rpm on my evo

 

looks like u having high rpm lockouts, it most likely the clutch set up u got, maybe it needs to be adjusted at the pedal, try that, and if it doesnt work out for u then u would have to take the tranny out and inspect the clutch/flywheel/Pressure plate and the pilot and throw out bearings. I had the same problem, i used a set of brand new stage 5 competition clutch kit and it locks me out everytime i shift into 2nd, 3rd, 4th, and 5th at anything over 8k rpm. good luck!

 

Adjusted the pedal, and the only issue that seems to still exist is 3rd grinds terrible, so I'm going to replace everything related to 3rd, and see if it goes away.

 

so it works now after u adjusted the pedal?

 

Yes 2nd seems to go in with no issues now.
