How can you find the gear ratio on montecarlo ss?
There should be a code stamped into the axle tube of the rear end. You'll have to find this and look for a site that decodes the letters. As far as I am aware, all Monte SS were put out with 3.73 gears.....some posi and some not.
How do you find the ratio of 800 and 640?
you would want to find a common denominator -- in this case 160 is the largest common denominator
800/160=5
640/160=4
therefore the ratio would be 5:4 (said "5 to 4")
Place a 10 amp fuse in the FWD fuse spot. This puts the car in FWD mode for towing purposes . Try moving the car. If the jerking goes away its probably due to the rwd or awd clutch pack at the rear of the transmission. Dont drive the car fast at this point , this is just for test purposes. Let me know what happens.

How do you know if you have a Locking Rear Differential?
Floor it. If both tires burn rubber or turf grass you have locking rear. Lift both rear tires off the ground with your transmission in neutral turn one wheel in a forward direction, if the other goes in the same direction you have a locking differential, if it turns in the opposite direction you don't.

You will need to remove the plate that's on the back of the rear end housing and look inside at the gears to know for sure.

Where do you put in the rear differential fluid?
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.

That all depends on the size of the rearend itself, the 3.46 gear has nothing to do with it.
How do you tell posi rear end?
You have to jack up the rear wheels and spin one of them and look to see if the opposite rear wheel spins and if so it would spin in the same direction. A open diff. will have the opposite tire spin in the other direction and a limited slip will some times leave the other wheel standing still and slowly start turning in the same direction after a certain amount of revolutions are made by the wheel you are spining by had to check as these work off of clutch plates and need friction to engauge them.

How do you know if a GMC Safari has a Locking Rear Axle?
Several ways: 1) put one rear tire on a jackstand and see if the vehicle will drive off the stand - if so it's locking/limited slip. If not - open. 2) Lift the entire rear end up and w/the tranny in neutral spin one tire by hand. If the other spins the same direction it's a locking diff - if it spins the opposite direction - open diff. 3) Put one rear tire on grass and the other on pavement and floor it. If the one in the grass does all the spinning and you barely move - open. If you put rubber on the pavement - locking. 4) VIN Code will tell you.
More comments: The locking rear axle on the later model Safari/Astro is a "fly weight" locker that works like an open axle until it senses too much speed difference between the two rear wheels. When that happens, there is a fly weight that is thrown outward to lock the rear axles. So, Item #2 above, won't work on this axle if you turn a wheel by hand since you can't get enough speed difference (unless you are Superman). Items #1&3 will work OK, just be careful. Regarding Item #4, the VIN won't tell you about the axle. The easiest way to determine if van has a locker is to look on the RPO code placard on the edge of the passenger front door. If it has "G80" listed, then the van has a locking differential. If no G80 listed, then it is an open axle. By the way, if it has "GU6" listed, the van has a 3.42:1 axle ratio. If it has "GT4" listed, the van has a 3.73:1 axle ratio.
Jack up the rear of the van. Place the gear selector in neutral. Rotate the rear tire by hand. If the opposite tire revolves in the same direction then it is posi. If the opposite tire revolves in the opposite direction then it is not posi.
I had a similar problem with my Ford F350 automatic transmission between 2nd & 3rd gears. The dealer said I needed a new transmission, which would've been covered by the warranty, but since I only had about 18,000 miles I thought that seemed unlikely.
A mechanic friend disconnected the battery for 10 minutes to reboot the truck's computer, and I never had a problem again. It's free to try this out and of course, can't hurt. Take care reconnecting the battery correctly, and note it's important to take the full 10 minutes to let it completely power down.
Might be a longshot but worth a try.
What is the gear ratio in a 1977 Toyota truck?

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.
