Spedo & gear changes

[1bad383]

Hi, I am finally swapping out my 4.56 gear for a 4.11 What is the easiest way to re-calibrate the spedo so it reads correctly. Thanks for the help!!

Sure!

The best resource for this information will be on the archived TDP Books.

All the 6.5 Articles so far have been collected together in one book, one of the articles you're looking for is:

Vehicle Speed Sensor Buffer

The link to the books is here:

Basically, you're going to make some jumper changes on the VSSB.

When I changed gears couple years back I followed the instructions in Jims book it was the easiest part for the whole job.

Ditto on above - I used that article to re-calibrate mine and it was a snap! Very good book to have around.
