Hi guys (and girls) , im about to purchase my second b-series , I have a 6 speed manual BA mkii ute running 310rwkw ... and I just put a deposit on a BF auto 6 speed ZF running 298rww, only think I noticed aside from a crunch / scrap sound from the rear driver side (assuming its a bad bush) was the gearbox. I'm just wondering if it's normal for a ZF box to be very rough and snap into gears like a trick kit or shift kit. I am unsure if it's been built and strengthened to suit the power or if its just a standard box ( all the other ive driven havent been so rough , but werent running as much power either), the owner selling it says it was normal and adjusted for the tune - just checking to see if that's actually the case or if im buy a dodgy box. Its not slipping and gear changes are fast and when I stomp it , its manly when cruising around in "drive" 1st to 2nd and 2nd to 3rd really seem to snap you back a bit... any info will be helpful guys, thanks... if I left anything just ask and I will submit more info.
