Speedometer Scale Variables such as the vehicle'south axle ratio and tire bore impact the accuracy of the speedometer. The post-obit speedometer drive gears and driven gears are available for the 700R4 / 4L60 transmissions. Nigh cars and trucks with low rear end ratios volition take a xv molar drive gear. There are two driven gear housings, one for 34 through 39 tooth driven gears and one for 40 through 45 tooth driven gears. Look at the bottom of the speedometer confront for the numbers 940, 960, 1000, or 1020. These numbers are the number of revolutions the speedometer cable must turn in ane mile of travel. Your speedometer may or may not bear witness a number. Nearly speedometer from 1965 on use 1000.

Twelve speedometer driven gears are available for the 700R4 / 4L60 transmissions to calibrate the speedometer with various beam ratios and tire diameters. The number on the driven gear housing must match the number of teeth on the driven gear. Unless driven gears with more than than 45 teeth and / or bulldoze gears with fewer than 15 teeth get available, it volition be incommunicable without using a ratio adapter to have an accurate speedometer with rear cease gear ratios lower (higher numerically) than iv.x:one, unless 27 inch or larger tires are installed.

To determine your tires truthful bore in relation to determining what speedometer gears you lot need, measure from the ground up to the center of the axle and then multiply by ii. The actual run out of the tire can be equally much as two to 3 inches less than what the circumference of the tire measures. In issue your tire has two diameters.

To determine your rear end ratio, raise both tires off of the ground, turn both tires at the same time one complete turn, at the same fourth dimension count the turns of the drive shaft, this is your ratio.
