SOURCE: 2002 pontiac sunfire has check engine light

Your problem is typical for these cars. The throttle position sensor is bad. Go to Auto Zone and have them check the codes to confirm this. i've seen this many times, that's usually the problem. It makes the car feel like the brakes are on. Hope this helps. Let me know. Phil

SOURCE: where to check/put in transmission fluid in 2005 Pontiac Sunfire

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,

SOURCE: check automatic transmission fluid 2001 pontiac sunfire

You need to raise the vehicle and start it. Remove the plug near where the passenger side driveshaft comes out. The head of the plug is 7/16. Trans fluid will stream out of the hole when the engine is running when the transmission is full, If fluid doesn't run out, fill the trans until fluid runs out. The fill cap is red and it is on top under and around the air cleaner box. If you need more help let me know.

SOURCE: getting a code P0440 on my 2002 pontiac sunfire.

the reason there is a P0440 = lare leak evap sytem. this can be caused be several things like a vent valve. which need to be close to check for leaks and if that stuck open this will set a p0440. or there is another problem. but i would start with a vent valve. there is a way to test it but you need a scan tool to do this. this is a common problem. 2734 GM Tech.

Transmission 4T40-E leaking at vented cap


most likely a dirty filter. also the slip can be coming from the tranny being dry. my bro has a 94 camero put all new seals in and still leaks. sometimes transmissions malfunction and build too much pressure inside and need rebuilt

What kind of auto trans fluid


The 2003 Sunfire has been updated from Dexron II or III to Dexron VI per a Technical Service Bulletin from GM.

Automatic Transmission, 4T40-E Initial Fill..........6.5 liters
Automatic Transmission, Total Fill 4 speed 4T40-E..........12.2 liters


Good luck and hope this helps, if you do use Synthetic transmission oil, make sure it's a Low Viscosity Synthetic Transmission oil. High viscosity transmission oil will cause the gear shifting to stick and will cause shifting issues.

Thank you for using fixya and good luck.

Where is the dip stick for transmission oil


Looking at the motor from the front, in the middle all the way to the back, near the windshild. It has a red o-ring handle. Three speed 3T40 transaxles (2.2L only) will have a dipstick, whereas the four speed 4T40-E (2.2L or 2.4L) will not have a dipstick. The 4T40-E has an oil check plug located above the pan in the center of the torque converter side of the transaxle; it is recommended to check fluid only when a leak has occured.

Good job.

Where is the dipstick located for the transmission fluid on a 2005 Pontiac Sunfire


According to the owners manual unless you drive in hilly, or heavy stop and go traffic like a taxi, you should never have to add trans mission fluid unless you have a leak. The manual doesn't even give a fluid capacity for the auto transmission. So I guess when you have to have the auto trans. filter changed, you have to take the car to a transmission specialist. If in fact the filter even needs to be changed. The manual leaks you to believe that the transmission fluid and filter are lifetime products.

How do you check tansmission fluid level in 2002 sunfire? 2.2 engine


Ensure that the transaxle case temperature is 70° to 90° F (21° to 32° C). With the engine running, shift transmission through all gears. With engine idling in PARK, remove the check plug from the transmission. If transmission has been overfilled, allow fluid to drain out. If no fluid drains out, add fluid through the TRANS FLUID fill cap under the hood on the driver side in 1 pint (0.5 liter) increments until it slightly flows from the check plug. Reinstall the check plug.

Please let me know if this information is helpful. Positive feedback is appreciated. Thank You!

I have a 200 Pontiac Sunfire when I put the car in gear it takes it a little bit of time to actually go into gear. I have seen that there is some fluid leaking out. What do I do?


I am thinking that you have an automatic transmission so if the fluid that os leaking is pinkish in color, your shifting problem is from low tranny fluid. You must fix the leak first and then top up your tranny fluid. That should probably fix your shifting problem

1998 SUNFIRE GT TRANSMISSION PROBLEM


There are 3 transmissions that could be in your car,the 3 speed auto and 4 speed auto overdrive,and of course the manual 5 speed.The 3 speed is designated the 3T40,the 4 speed auto is the 4T40E trans.To check the fluid level,first,the car has to be warmed up to at least 100 degrees Fahrenheit.The car has to be raised in the air,as there is a steel plug in the trans case that has to be removed to check the fluid level.The plug takes an 11 mm or 7/16" socket or wrench and is located on the passenger side of the trans case,near where the passenger side axle engages into the trans.The procedure is to warm the car up to at least 100 degrees,engage the shifter into each gear selection pausing for about 5 seconds in each gear,then remove the plug.If fluid drips out,it is full.If no fluid drips out,add fluid through the top of the trans after removing the red plastic cap,and make sure to use a long funnel to avoid a mess.Add fluid until it drips out the hole.When done,replace the plug and cap.Just a note,a transmission does not "use" fluid like an engine uses oil.If you have to add fluid,that means there is a leak that needs to be repaired.Good luck
