    I have a 95 Tacoma 2.7 5 speed manual 4X4. I hooked up a tach to see how many RPMs it is running at 55mph. It is running at 2050 RPM at 55. That seems aweful low to me for a 4 cylinder. I am wondering what the factory gearing is and how many RPMs it should be running?

    THIS CHART IS FOR '95.5-04 MODELS ONLY!
    The axle code for your rig can be found on the manufacture's sticker located on the driver's side door jamb as follows:

    First digit:

    A = 7.5" ring gear
    B = 8" ring gear
    Next two digits:

    01 = 3:42
    02 = 3:58
    03 = 4:10
    04 = 4:56
    05 = 3:15
    06 = 3:91
    07 = 4.30
    Last digit:

    A = 2 Pinion, Open
    B = 4 Pinion, Open
    C = 2 Pinion OEM Limited Slip
    some '98-00 models have shown a BO code of "???" on the door plate; so far this turns out to be a 3.91 gear ratio, at least for the 5sp. RZN171L-CRPDKAB with factory 31s/265s should be 4.56 with the AT.

    Thanks. Now just have to figure out what gears are in there. I would like the rpms a little higher at 55 mph.
