Trying to find were to check and see if i need more transmissin fluid in my 2002 pontiac grandamGT

To check the transmission fluid level in your car you have to raise the vehicle up and take out the transmission fluid check plug in the transmission. It is locate just below and forward (Towards the front of the car) of where the right axle goes into the transmission housing. To fill it take the plug out then remove the red cap located on the upper side of the transmission housing. You will need a long funnel to add the fluid. Add fluid until it can be seen dripping out of the check plug under the car. Then replace the cap and reinstall the plug. (There is no dipstick on your car)

Google search this (how to check trans fluid on 2002 grand am GT) there are e few recommendations and descriptions that will help you understand. possibly go to pontiac site and download a diagram or location of inspection and fill locations

No dipstick . There is a 7/16 check plug just below the passenger side axle. engine must be running and the transmission warm to touch. very difficult to do without a lift because car must be level.The fill port is a red threaded cap on top of trans. good luck
