Granny gear is a term used for truck manual transmissions extremely low first gear.This type of transmission would be one that when driving normally around town you would start out in second gear.the very low gear reduction of the first gear would be used for low speed pulling or crawling where the extra torque is needed.

ANS 2 - Granny gear is also used in bicycles. On any bike with three chainrings, the smallest, innermost ring is often referred to as the"granny", or the bailout gear. Having to drop to the smallest chainring is often seen as the last resort before having to get off and push the bike, if the incline gets too steep for any of the "regular" gears.

Ratios (mathematical)

There are four ways to find a ratio.

1 A dealer can normally tell from the vin number.

2 There are normally tags or labels on the axle that have part number, gear ratio, and fluid requirement

info.

3 You can count how many times you have to turn the driveshaft to get one complete turn of the tires.

4 You can divide the number of teeth on the ring gear and divide by number of teeth on the pinion.

One key to this design problem is to remember that gears must have a whole number of teeth. It is impossible to roll a gear against another gear that has, say, half, a tooth somewhere among the whole teeth. So gears always have a whole number of teeth.

Another key is that the gear ratio is the ratio of the numbers of teeth on two gears, N1 divided by N2. The result of this division often produces a fraction AND the fraction is often ROUNDED OFF in printed materials. Because of this round-off, you cannot be certain what the actual fraction is. This means that, even when you find whole-number values for N1 and N2, you cannot be certain that they represent the exact numbers.

So, here is how to find the pair of gears from a given gear ratio such as 4.11. First, examine the fraction, 0.11, from the ratio. Find a whole number m such that m times the fractional part of the gear ratio gives another whole number almost exactly? Try m = 2, 3, 4 ... up to 16 or even more until you find a good fit.

For the given problem, 9 x 0.11 = 0.99, which is almost 1.

That whole number m is the SMALLEST possible number of teeth for one gear.

Multiply the gear ratio by m and round to a whole number to get the least number of teeth on the second gear. So, 9 teeth is the smallest number of teeth for one gear and 9 x 4.11 = 36.99 (that is, 37) is the smallest number of teeth for the other gear.

You can multiply the number of teeth on both gears by any whole number without changing the gear ratio. So, 2 x 9 = 18 teeth and 2 x 37 = 74 teeth also have the ratio 37 / 9 = 4.11111...

Here is how to tweak the result if the fraction you chose didn't give a satisfactory result:

Multiply the number of teeth from the trial answer by any whole number, say 2 or 20.

20 x 9 = 180 and 20 x 37 = 740

Now subtract 1 from the number of teeth on the larger gear and calculate the gear ratio.

740 - 1 = 739 and 739 / 180 = 4.105555...

Alternatively, add a tooth to the larger gear and check that ratio: 741 / 180 = 4.116666...

if its whiny gears, banana skins,, seriously,, but it wont last long, & its not really that good for the diff.

if its bearings,, lots of grease, but again, only a very temporary fix!

if its the gears, they need to be re-hardened, its often cheaper to get a second hand diff head. or new gears.

if its the bearings, replace them.

Yes, although depending of whether you have a front wheel or rear wheel drive, the differential will be set up differently. A differential is just a set of mechanical gears that equalizes the power between the left and right drive wheels, particularly when cornering, when the outside wheel travels further than the inside wheel.

It depends on whether or not your car needs a differential. Nascars do not have a differential because those cars always turn in one direction throughout the race. Gokarts (yeah, I know,they aren't cars) do not have a differential.

If 4wd yes you also have two other options. You can gut the transfer case, make it just an extension off the transmission. Or you can buy a new driveline off a 2wd ram which will be longer. Longer shaft will reach transmission and allow you to drive. you will also have to remove the front driveline.

the car has a cable between the key and the transmission shifter. if this cable is worn it can be very difficult to shift from park, and will only get worse. I just disconnected mine, but you will probably want to get a new one installed at any auto shop. In our 92 Camry, my brake switch had gone bad. We had not noticed the rear light out, but I had extreme problems shifting out of park to either drive or reverse. Once the switch was replaced, smooth sailing! The car was not sensing that the brake was depressed to release the gearshift button.

You have to remove the rear cover on the differential housing. Once the fluid is all drained, replace cover with new gasket (or use silicone sealer) and refill through 3/8" square plug on the side of the unit.

One other point to this. Replacing the fluid can be a bit tricky. By the time you get yourself, your tools, and your bottle of fluid under the truck it can be a challenge to the fluid in the differential. To ease the problem, get a small section of hose to connect to the spout of the bottle and then run the other end into the differential and squeeze. It is pretty easy and faster.

Is it an automatic? Time for a new transmission... If a stick and 1st, 3rd, 5th are ok, then you have a possible shift cable problem. You should be able to see them on top of the trans. If everthing is moving properly the trans has an internal problem.

Most analysers provide an automated differential with the white cell count, red cell count, and indices. If for some reason, the differential is rejected, or flagged on the automated differential provided, the differential must be performed manually by properly trained technologists. A manual differential involves making a smear on a glass slide and staining the slide with Wright's stain which is a combination of acid and basic dyes. The stain results in white blood cells staining blue and the red blood cells staining red, platelets also appear blue. 100 white blood cells are counted under a microscope-dividing them into the 5 white cell types and evaluating the cells for abnormalities. The red cells are observed for size, shape, and hemoglobin content. The number of platelets is estimated as well. The absolute number of each white cell line is then reported using the percentage of each cell type and with white cell count.

In conventional road vehicles an electronic differential is usually a mechanical differential that uses an onboard computer to directly control and adjust the torque split and difference in wheel speed across the axle. This is acheived by electronic actuators engaing clutch packs and locking mechanisms to acheive the desired traction condition. It is esentially a computer controlled LSD and differential lock in one. This means the computer can calculate the optimal torque split and actively vary it on the fly. In electric vehicles with separate motors driving each wheel, an electronic differential is simply a computer that controls the wheel speed of the inside and outside wheels based on the steering wheel angle, to acheive the same effect as a normal mechanical differential.

The rear differential fluid goes directly into the rear differential. There is normally an inset plug that has a square drive on it that accepts a 3/8" ratchet or ratchet extension. Remove this plug. If fluid comes out, you do not need to add any. If no fluid comes out, add enough of the fluid recommended by your vehicle manufacturer (normally 80/90 gear lube, but not always) where you took out the plug, until it starts to seep out the plug hole. Replace the plug and you're finished.

When the fluid falls below the bottom of the filler plug hole it is time to add fluid. Add fluid until the level reaches the bottom of the filler plug hole. In other words, add fluid(while parked on a level surface)until it begins to run out. I have a 99 Tahoe and the manual doesn't list any quantity/capacity for the differential, only how to check the level and refill if needed. Mike

you've made me think about my own 4x4 which has a posi-track rear end. The reality is that most 4x4's are actually only 2 wheel drive. For example if u drive half in the mud and half on the pavement - only the wheels in the mud will have power to them and all power will be lost to the wheels on the pavement. That is just stupid for somone who loves wheelin. Jack one wheel off the ground with a floor jack under the axle and see if u can take off (slowly) in two wheel high (don't lock in the front) - hold on I'm going to go try that right now...if the wheel off the ground spins and u r not getting power to the wheel on the ground then hey - it's worth it to put in the locker.

BRB - well looks like I'll be installing a locker. The tire off the ground spun like mad and if I was stuck I would be going a whole lot of nowhere...

Yes you can. However, it's fairly complicated. You need to source the parts from a junked car of the same year and equipment. It's probably not worth it... less hassle to just trade in for an ASR-equipped car.

Just keep watching eBay or craigslist or find a car being parted on eBay there are tons of them and just keep asking all of them if they have a switch.

If the system is already installed why do you need to get parts from a salvaged car? It seems you can find a switch anywhere.

The full and correct answer to this problem would take up a book, as many things could cause it and a complete list is almost impossible. Possible Causes: *Bad Fluid *Bad Filter *Bad or clogged lines *Bad wiring to the transmission (if overdrive) *Bad Lockup converter (if overdrive) *Bad or incorrect Band Adjustment *Problem with the VSS (vehicle speed sensor) My suggestion would be to take this to a reputable transmission shop and have them check it out.

Of course my first question is, are you moving? If not, have you snuck up on it late at night? Is the engine running? It's very common for a tire to spin when the transmission is engaged and engine running, the main purpose of a transmission is to transmit the rotational power of the engine to the tires. You neglected to say whether the tires are in ground contact or not. If they are your idle is set WAY to high, if not, wheel spin is completely normal with either a manual or automatic.
