Hello! I apologize my english first because I'm Finn and it's not good, but I hope I can get here answer to my problem as I didn't get it in Finnish forums.

My C36 is started to have some acceleration problems. When I accelerate with kickdown 0 to 100km/h (0 to 60mph) it feels like it doesn't go with all power. It takes with all power in about 5000rpm and then switch to 2nd gear and have same issue in there until it's again in about 4000-5000rpm. Sometimes if I accelerate with full thorttle in 20-30km/h (20mph) it goes with all power, but sometimes it do same like when I accelerate 0 to 100km/h. Sometimes when it switch 1st to 2nd, it goes all power there with 2nd gear, sometimes not.
Sometimes it doesn't accelerate normally when I accelerate in half throttle but it is fixed everytime when I remove throttle and then accelerate again in half throttle.
So the main problem is in full throttle accelerating...

I really hope you understand my problem with my english, 'cause I really need help to fix this problem!
Cheers!
