Some do and some don't. The quickest way to tell if you even have a Limited Slip or Posi-Trac is to jack both rear tires off the ground at the same time. Then try to rotate one side in one direction or the other. If you have a LS the other tire will follow along but maybe a little slow or not respond to your movements real quick. That depends on how tight the clutch pack is. If you have an open diff then the other tire will rotate in the opposite direction.
I can say this with absolute certainty, every single T/A from 69-81 was equipped with a Posi...No matter whether it had high or low gears in it. Once GM took over in 82 and the T/A was more Chevy than Pontiac I can't say.
Yes, a 2000 Trans Am does have posi traction. If a car has posi traction, it means that the car has a limited slip differential. Posi traction is good to have when traveling in ice or mud.
It was an option.
All 79 Trans Am...Yes. Firebirds....NO
Z28's came with a limited slip differential. Trans Ams had posi-traction.
the correct term is posi-traction which refers to the power to the differential then to the rear wheels, a posi-traction equipped vehicle provides power to both drive wheels if one of the wheels starts to slip, a non posi-traction vehicle only drives one rear wheel.
The rear end in a 1988 Trans Am refers to the rear axle assembly, which includes the differential and axle shafts. Most 1988 Trans Ams were equipped with a 10-bolt rear differential, commonly found in GM vehicles of that era. This setup was designed to handle the performance demands of the car, especially in models equipped with the more powerful engines. Upgrading the rear end can enhance performance and traction for enthusiasts.
a 1989 trans am gta has a limited slip differential
The flashing light is letting you know your differential is locked in for more traction
The term "Non Limited Slip Differential" is Ford's way of telling you that your differential isn't special. A limited slip differential has clutches in it that stop a spinning wheel (the one that isn't getting traction) and send the power to the one that has traction, so the vehicle can get out of snow or mud. A non limited slip differential can only send power to one wheel at a time, which is the one with the least amount of rolling resistance (the one not getting traction).

To determine if a 4.10 rear end is posi traction, you need to check the specific vehicle's rear differential specifications. A 4.10 refers to the gear ratio, while "posi traction" (or limited slip) indicates that both rear wheels can receive power simultaneously for better traction. Not all 4.10 gear ratios come with posi traction; it depends on the differential setup. You can usually find this information in the vehicle's specifications or by inspecting the differential itself.
A locking differential is used in tractors which provide increased traction compared to a standard or open differential. It restricts each of the two wheels on an axle to the same rotational speed without regard to available traction or differences in resistance seen at each wheel.
