• Turns out that I do have overdrive. I just needed to get a stretch of fourth gear to get it engaged and happy, now it seems to be working in third as well.

    Will give it a proper test on some A roads or MWay, when I can.

    Trying to test it on urban residential roads is not easy.

  • My GT6 used to be like that (and I assume it's a similar overdrive setup) - it woudn't flick straight in at times, you had to go for a while in third or fourth, sometimes going up and down on the revs a couple of times before it lurched in. The Dolly Sprint just went straight in, any gear / rev count.

    I remember reading that it was apparently relatively common, but I'm not sure what the problem component was.
