CSR Classics - Chevrolet 3100 shift pattern

Just got the truck to 620, and I&found an odd pattern. It doesn&have enough acceleration and power to skip gears efficiently, so my hopes of the 3100 being that great mostly lie in Multiplayer, but it might have the Model B Disease and not get much help from crew members... Going for all perfect shifts nets around a flat 9 seconds, but getting wheelspin when shifting into the second gear seems to speed you up at least 50 milliseconds. It¬ the greatest, but again, it&nowhere close to the Bora Gr .4.
