Trying to figure this one out. I believe it's either the clutch, cables, synchros, slave or master cylinder. I have an h22a non lsd tranny currently have a stage 4 Bully clutch that is has the rating to handle the power. I am making 400whp and 300lbs/tq. Now the problem is at the track I have a really hard time shifting at high rpm's <6500rpm's. At lower rpm's it shifts fine, no grinds or anything, it's just at higher rpms's. I searched around, but haven't found out a for sure solution. Anyone have any ideas?? Thanks

 

bump...for help

anyone?

 

What exactly is the problem? Does it not go into the gate, feels like it hits a wall? Does it grind? Which gears? It can be a couple of things.

What type of mounts are you running? Too much engine/trans movement during shifts can cause misshifts.

Too much play in the shift linkage from a loose joint on the shift rod or worn bushings can cause shifting issues.

Improper adjustment of the clutch can cause shifting issues.

A bad pressure plate or sprung clutch disc can cause shifting issues.

Internal tranny problems like Worn syncros/hub/slider/gear or bent/worn shift fork/shift change assembly can cause shifting problems.

 

cables issue, tie them together with zip ties. Because of this shifting issue is why the H2B came about.

 

Shift cables or clutch/clutch adjustment most likely.

 

No problems with the mounts. It feels like it hits a wall, no grinding, it happens pretty much in every gear at high rpm's. I have a sprung stage 4 Bully clutch right now. Most people think it's the clutch, so I will probably go with a CC twin disk.

 

Would like to go with an h2b, but no one has one for a cb7

 

I'd check the throw of your clutch. Adjust the Pedal. If your clutch is disengaging at the bottom then extend the plunger so that it will disengage sooner.
