300ce (full throttle) shifts into 2nd at 3500rpm?

[mercmike32]

Hello, I have a 1992 300ce with 130k miles. It is a stock m104 engine and when I take off of a dead stop (engaging the kick down) the car shifts into 2nd at 7000rpm then when it shifts into 3rd it only goes up to 3500rpm. The throttle cable has been toyed with by the way by my mechanic and no matter where he or I set it to this still happens.

Any ideas???????????????????

Thank You in advance for any info!
