When I launch in 1st and then try and switch to 2nd at the redline it grinds, if I switch at 30mph I feel some pressure like its hard to push it into 2nd but it goes without any grinding sound. If i downshift into 2nd going at 40+mph in any gear it grinds.

When I go into 2nd gear and try and redline it doesnt let me go past 7k ish its like the ecu or engine is stopping me? It just wont let me go any higher even if I hit the gas, it just staggers downn. Everything seeems healthy, I had a clutch job very recently do you think something went wrong in the instalation?

This only happens to and in 2nd gear.
