    Hi Toppa,

    I think your handbrake may be sticking or be adjusted too tight.

    My POS does something similar when its not off properly. (3 speed auto and LT95 TC......same principle though)

    cheers, DL

    An interesting update.......

    Still havent fitted the ATB but i did clean the MAP sensor which has influences on fueling (and possibly gear changes) and it has made a remarkable difference. I still have backlash, but the gear changes, both up and down, are much much smoother.

    The MAP sensor was absolutely chock a block full of oily gunk!! Cleaned the EGR while I was there. I should get around to removing it one day!

    If the centre diff is shagged you'll get lots of backlash. I replace the TC in mine about 2 weeks ago, and even with the centre diff locked there you could still turn the output flanges 10-15 degrees in opposite directions, then turn them a little further with an accompanying graunch.

    Having replaced the rear diff and TC with supposedly good used units the backlash is significantly reduced.

    cheers
