    Default E40 manual transmission gear ratio table?

    I am trying to make a auto file into a manual file. I have located the trans type, lockout solenoid, in raw hex and corrected them. I also changed it to auto trans fitted, and corrected the reluctor tables, speedo tables, and BTM gear ratio tables. Cruise only works in gears 1-5, 6 doesn't work. Using scanner PID trans current gear it reads incorrect gear ratios. says I'm in second when I'm in first, 6th, when I'm in 5th??

    If I change the rear gear ratio to a higher value, then cruise works in 6th, but gear ratios are still off, and speedo is then off. So I need to change the gear ratios.

    There isn't a T42 in place, so its clearly using gear ratios stored in the PCM? Anyone know were? Even if its in raw hex, just tell me the constant for it, I can update the checksum, and work in raw hex.

    H_SSRfileintoGrandPRI.tun

    Change extension to bin in order to open. and I haven't changed B0501 yet! trans gear tables but it makes no difference. Note do not flash this file you will corrupt the PCM!!! Just for comparison

    I can't it has other attrabutes I'm after, that no other manual trans file has.

    It registers 2-6 grears there just off, it's like the output shaft rpm, table needs to be adjusted if there is such a thing?
