i notice when i floored the X pedal.......the rpm reaches to about 5000 and keep sticking there and the gear does not change from first gear.....but if i release the x a bit it changes as normal.....if i am driving slow all my gears change.....i also noticed that my speedmeter stop working ,.......what could be my problem?

 

bump!

 

Sounds like VSS problem. Fix the speedo/VSS problem and then go from there.
