Shandra1174, As silly as it sounds, the Pontiac Sunfire 4-speed automatics and some of the later model 3-speed automatic transaxles don't have a dipstick to check the transmission fluid level. I'm not sure why GM decided to do this, (It's Crazy), but they state that as an owner you do not have to check the fluid level, that it must be done by a professional. To check the fluid level the vehicle must remain level and must be raised high enough to access the fluid level check plug on the transaxle. With the vehicle safely raised and supported, start the engine, move the shift lever through all gear ranges, ending in park. With the engine running, (remember this car is probably up on a hoist at this time), and the transaxle at normal operating temperature,(having idled for three to five minutes), you are to remove the fluid level check plug on the transaxle, it is located near the transmission pan, adjacent to the engine oil drain plug. Place an oil container under the check plug and remove it. Observe the fluid as it drips into the pan, indicating correct fluid level. The fluid should be at the bottom of the check hole. If fluid pours out excessively, the transaxle may have been overfilled. Make sure the vehicle is level. If no fluid drips from the check hole, add small amounts of fluid through the vent/fill cap at the top of the transaxle until the fluid level is at the bottom of the check hole. You can verify this procedure in the repair manual. You can purchase a Haynes manual for the vehicle much much cheaper than a General Motors manual. I found this silly process to be how they designed it after I purchased a 2001 Sunfire, and I too looked high and low for the dipstick or any information telling me where it was. If your like me, and like to know whats going on with your car, this procedure is not what I wanted to find. It was very upsetting to me. I hope it helps, at least now you know why no dipstick. Good luck, PapaJohn

The transmission dipstick on a 1994 Pontiac Sunfire is located on the left side of the engine. It connects to the transmission via a long tube which also allows for adding transmission fluid.

Some early model Sunfires have a dipstick. In my '96, the dipstick is located near the firewall, down and inboard from the brake fluid reservoir.

The transmission dipstick is located about 1.5-2ft from the fender on the drivers side, about at the back of the engine, in front of the windsheild/firewall.. it's sometimes yellow, or black. it's also pointing upwards at an angle

There is no dipstick for the transmission. It has a check valve on the side of the pan.
