SOURCE: 1995 sunfire wont shift gear

There were two different automatic transmissions in the Sunfire that year,the 3 speed trans designated the 3T40,and the 4 speed trans designated the 4T40.If your car has the 4 speed trans,there will be a circle around the "D" on your gear selector indicator.The 3 speed trans will not have a circle around the "D".The 3 speed trans works off of a cable called the TV or Throttle Valve cable.This cable should be checked where it engages the throttle body around the area where the throttle cable attaches to the throttle body,on the engine.If the cable becomes disconnected for whatever reason,the trans will not shift out of 1st gear in most cases.If the car has the 4 speed trans,this model trans is totally electronic,and the vehicle should have the codes pulled out.For every trouble code,there is a diagnostic route to follow to repair the malfunction.

SOURCE: My 1997 Pontiac Sunfire's clutch

Check Your Clutch Fluid It Just Like Checking Your Brake Fluid In The Engine Compartment. If Its Low You May Have Got Air In The Line Which Will Cause The Clutch To Feel Empty. Make Sure Its Full Then Get In And Push It 3 times and hold then get out and check it again seeing if its emptied the reservoir. Keep Adding until the clutch feels good again. make sure that after doing so there isn't any dripping off the bottom of the car which would indicate the line need to be repaired.

Next If The doesn't do it with the car off push the clutch very slowly and listen for any kind of suction sound near your feet. sometimes it leaks around the pedal. If you dont have any fluid on the floor board then all should be well.

Then fallow the line all the way to the transmission looking for fluid.
It is pretty easy to find as it doesn't dry.

Most vehicles use dot 3 brake fluid but your vehicle may differ check your clutch reservoir cap for specifications on fluid.
if it does take brake fluid do not spill it on your paint as it will take it down to the bare metal in no time.

I hope this helpful and look forward to hearing your results if you need more help.

Sincerely,
Michael Scott

SOURCE: I have a 2002 pontiac grand am gt that is'nt shifting gears right

My daughter has a 2003 with the same problem. She took it to a highly regarded transmission shop. They told her it is not the transmisison but an engine performance problem. She took it for an oil change to check the filters etc and the fuel filter is bad. I will follow up if that fixes the problem.

2005 pontiac sunfire 2.2 ecotec. when i put in drive i hear a loud bang and when driving has a quieter bang when shifts gears the motor mounts don't move much what could it be?


Sounds like transmission is low on fluid and gears are banging together when they shift. Probably should check the level and add to fill and hope that no damage has been done. I hope that helps you figure out your problem.

2000 pontiac sunfire 2.4L twin cam. When put in drive I hear a loud bang and when driving it has a quieter bang when it shifts gears.


Check your motor mounts, it sound like your motor is rocking back and forth. You can confirm this by watching the engine while someone shifts it in and out of gear for you.
