![]() ![]() Another place a TH350 leaks is from the vent tube on the main case passenger side above the. Replace these two O-rings, lube with ATF from the trans dipstick, and install all items. Pull out the plastic driven gear and look inside the bullet and there is the second O-ring. Unless driven gears with more than 45 teeth and / or drive gears with fewer than 15 teeth become available, it will be impossible without using a ratio adapter to have an accurate speedometer with rear end gear ratios lower (higher numerically) than 4.10:1, unless 27 inch or larger tires are installed.Ĥ5 will work, but will read about 3 MPH fast at 50 MPH. One O-ring is on the outside of the bullet. The number on the driven gear housing must match the number of teeth on the driven gear. Twelve speedometer driven gears are available for the 700R4 / 4L60 transmissions to calibrate the speedometer with various axle ratios and tire diameters. Your speedometer may or may not show a number. These numbers are the number of revolutions the speedometer cable must turn in one mile of travel. Look at the bottom of the speedometer face for the numbers 940, 960, 1000, or 1020. ![]() There are two driven gear housings, one for 34 through 39 tooth driven gears and one for 40 through 45 tooth driven gears. Most cars and trucks with low rear end ratios will take a 15 tooth drive gear. The following speedometer drive gears and driven gears are available for the 700R4 / 4L60 transmissions. Variables such as the vehicle’s axle ratio and tire diameter affect the accuracy of the speedometer. 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 time count the turns of the drive shaft, this is your ratio. The actual run out of the tire can be as much as 2 to 3 inches less than what the circumference of the tire measures. To determine your tires true diameter in relation to determining what speedometer gears you need, measure from the ground up to the center of the axle then multiply by two. ![]()
