hi..the transaxle converter clutch . tcc. uses a solenoid -operated valve located in the automatic transaxle to mechanically couple the engine flywheel to the output shaft of the transmission through the torque converter.that reduces the slippage loss in the converter.reducing emissions.but check the vss first.which is called the vehicle speed sensor.they both work together .if the vss is not working right it wont call on the tcc.
check this out..
thank u..

this is normally located under the hood next to the hood release lever if it is missing from yours then try www.autozone.com or go to your local Pontiac dealership in the parts department or an auto parts store like Napa or Autozone

SOURCE: what can cause overheating in a 2000 pontiac sunfire

Replace the thermostat. It will be fine after that. I know thats what everyone says anytime there is an overheating problem but in this case with the way the system works and it has been working fine up to this point, it's gonna be the thermostat.

SOURCE: How do you replace brakes on 1999 Pontiac Sunfire?

The engine size don't matter except when you order the parts. First you will want to chock the rear tires. This is a front wheel drive, when you jack the front, park wont work. you should also set the parking brake.
You will want a metric socket set and rachet, and a fairly large flat head screw driver.
Remove the wheel.
When you look at the brakes, you should see 2 bolts holding them on, If they have a star shape that looks like a screw driver might fit in it, it is a torx bit, you will need to replace the wheel and go get one. The guy at the parts store should be able to tell you what size.
I'm pretty sure it is going to be a regular hex nut, probably 12 or 13mm.
You can loosen them, but don't remove them yet.

First you need to depress your caliper. This can be done a couple ways.
I just insert a screw driver between the pad and the rotor(the shiny thing that the pads make contact with.) Carefully pry the inner pad slowly away from the rotor. Don't scratch the rotor, you can dig into the pad all you want, your putting new ones on.
Once the inner pad is all the way in, then you can remove the bolts and the caliper will slide out.
Remove the old pads and replace with the new.
Put the caliper back on, make sure you get the bolts tight.
Do the other wheel the same way.
The other way to get the caliper pushed in, by the way.
Remove the bolts, remove the caliper from the rotor, Use a large "c" clamp to depress the cylinder.

P.S. Do not under any circumstances remove your brake lines.

When you are finished with brakes and have tires replaced....

Caution!!! Before you start your car, pump your brakes a few times. Check your brake fluid. You more than likely wont need any, but you should always check it.
Also, do not add brake fluid before replacing pads, the level is going to be higher with new pads.

Back brakes will be similar if it is disc, if it is drum, do your self a favor and have some one else do it or get a service manual. I could walk you thru it, but you need more tools and you have to adjust them....
Better to pay $100 or so and have it done right.
