I assume this is an automatic transmission, you didn't say.
There is no dip stick on the transmission any longer.
You will have to go under the car to check. You may want to go to your local instant oil change and have them check the level.
If you feel you want to check it, here is a description of the location and process.

Make certain the vehicle remains level while checking the fluid.
Located just above the top sealing flange of the transmission oil pan you will find a threaded plug. Remove the plug and see if transmission fluid drips out of the hole. If so, the fluid level is correct. If not, remove the red fill cap on top of the transmission, driver side. Add fluid to the transmission until fluid dribbles out of hole.
Replace and tighten the plug.
Good luck.
Regards,

how to replace a 2005 pontiac sunfire thermostat

Should be in a housing just at the motor end of the upper radiator hose. Trace the upper hose down under the alternator.

Pull the hose off (be sure you have a way to catch the coolant first!) Then you unbolt the thermostat bolts and pull out the thermostat. REMEMBER which way it goes---the part with the "nose" points toward the radiator. Then clean both surfaces of the housing really good, and put on a new thermostat gasket. You can seal it with some light white grease, but just enough to make the gasket stick. Don't use goopy silicone sealant! Tighten the bolts but don't go crazy. Just enough to strain the muscles in your arm using a 3/8 drive wrench. Do NOT put your back into it. NICE and SNUG. Now you have to fill up the plastic reservoir tank. Then you run the engine for for just 30 seconds or so, then shut it off. Now you have to find the BLEED SCREWS and open them up so as to let air out of the cooling system. Then close the air bleeds. Repeat this filling up and running the engine briefly until coolant comes out of the air bleeds. Then top off the reservoir tank.

I think one air bleed is by the pipe where you put in the oil. Once you find it, look for another one like it. Sorry I don't have a manual for your car.

these things are "self protected" and cannot be worked on. Even the lights are optic and cannot be replaced.
Best solution is to replace the whole gage unit (about 50 bucks at a salvage yard).
The dealer will have to install it as it needs to be coded or programed once installed and it's a bear to get the dash apart.
Even better solution....just dive it. :)

locked my keys inside, can't find a door diagram online

I have locked my keys inside my 2003 pontiac sunfire, and I have bought a Slim Jim, however, I can not find a diagram of the inside of the door so I know how to unlock it. Please help!!

A slim Jim is a fishing expedition. What you need to do is not worry about diagrams. Realize that the locking mechanism has just a very few parts that interconnect. The key hole where you insert your key, and the lock button that go up and down (or in some cases forward and back) are mechanically connected. It's that connection your fishing for and trying to move. You need to 'fish' between the lock and the button and try and 'hook' that linkage and move it in the dirction that moves your lock button to the unlocked position. If you really need a diagram many of the car part web sites will display a diagram for car parts. I've unlocked alot of doors with the method described and have never seen a diagram for what I'm doing. Good luck!

Given that most of the trouble codes are for the O2 sensor, I think I would change it. The multiple misfires could be because of improper fuel/air mixture caused by a bad sensor. Disconnect the negative(-) battery terminal then change the sensor. Disconnecting the negative(-) should reset the computer and allow the fuel/air mixture to return to default allowing the engine to start.
P0130 - O2 Sensor Circuit Malfunction (Bank 1 Sensor 1)
P0134 - O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 1)
P0135 - O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)
P0300 - Random/Multiple Cylinder Misfire Detected

the radio won't shut off when door is open and car is off

Possible (rap) problem or door sensor?

If the radio used to turn off but now it doesn't then you have a short either in the wiring or in the radio itself. If you are knowledgeable about automotive electrical wiring and have a volt meter or test light you can troubleshoot it yourself to see where the problem is, otherwise you need to take it to a car stereo shop and have them check the 12 volt connections at the back of the radio to make sure the red (NOT BLUE)accessory wire to the radio is not showing 12 volts when the ignition key is turned off.

The tach first stopped working, and now it appears to work sometimes and working inacurately others. Minutes after the tach stopped, the speedometer became inacurate, slowly rising and pegging out over 110mph. It now appears at 55mph with the car parked. The other gauges (fuel and temp) appear accurate so far.The tach first stopped working, and now it appears to work sometimes and working inacurately others.

I have the same problem.. i installed a toggle switch for the fuse so at least I can reset it while driving.. its still a pain so Im thinking my next step will be to drill a hole through the plastic and put in a small metal post to stop the tach from going past 7

has anyone taken theirs into a shop?

The 03-05 Sunfire instrument clusters have a common problem where the stepper motors on the cluster's circuit board will fail causing one or more gauges to go out. It can be repaired though, check out this page for more on how to get it fixed - sunfire tachometer repair
