  • 3.42 gear adjustments

    Would there be a massive need for odometer/speedometer adjustment with the installation of 3.42 hears from 3.23?

    your speedo will be about 10% off.

          you also might run into abs/traction control issues too...not sure...most people just get a controller or spend the few bucks to knock that out.

              Not to sound like a jerk or anything but if you don't know the answer don't give the information or at least qualify it with "I think", or "I believe" or something.

              10% difference is only for 3.08-&gt;3.42, from 3.23-&gt;3.42 you will only be 6% off. Your speedo will be showing you going FASTER than you actually are. So if it shows you going 70 you will actually be going 65.8.

              You will have no issues with ABS or traction control. I changed both gears and my diffy when I did a swap so I needed a new ABS reluctor ring ($20 from slp), however, I believe you only need this if you change your diffy as well.

              With a 2001 you defintely have a standard 4 wheel disc ABS system.

                  maybe my calculations were wrong...323/342=9.44%...maybe thats not the way you figure it out? In that case I appologize.

                    No, that's 94.4%....the different is then 100 - 94.4 = 5.6% ;)

                      (1 - (3.23 / 3.42)) * 100

                      you divided 3.23 by 3.42 and got 0.94444444444 which is good, however, you then need to subtract that from 1 and then multiply by 100.

                      If you take it out a few more significant digits 5.6% is probably more accurate. But 6% will suit you just fine.

                          The only way he's got 3.23s is if he had them installed. And I don't know why anoyone would go from 3.08 to 3.23.

                            Either way if you do swap gears... any gears

                            Its going to mess up your odometer, you are going to be putting on miles faster then you should.

                            I went from 3.23s to 3.42s, I "think" no scientific calculation but I was getting 1.2 showing per every mile I traveled.(trip reset, at a mile marker to the next mile marker)

                            So mileage will jump on your car. I didn't care because I had a 94 with like 115k, its value was pretty much low anyways. Only reason I didn't do an upgrade form 3.23s to 3.42s with a rear axle swap on my 2000 was the added cost of having to fix my computer.

                            So instead I just installed a LSD unit instead of an axle swap.


                            Also doesn't mis calibrated gears cause autos to shift early?

                              That was the issue I was going to bring up.

                              I went from 3.08s to 3.42s and the gains were completely negated from the shift points being incorrect, until I got that fixed.
