The first thing I'd check is the level of the transmission fluid. Make sure the vehicle is level, and is up to normal operating temperature. Check It while it is running. If it's low, there's your problem. If it's okay, then you may need to change the transmission fluid and filter. The transmission filter is similar to a filter on an A/C unit. Like a screen to catch the junk in the fluid. It's located inside the transmission pan on the bottom of the vehicle. If you do it yourself, make sure you use the right type of transmission fluid. Filters and fluid are relatively inexpensive to replace.
With all of that being said, all of that information was for an automatic transmission. Not for a standard transmission. If your transmission fluid level is okay, and doesn't need changing. Take heart, that doesn't mean you're looking at a complete transmission replacement either.

According to the owner's manual:
Owners manual says change at 50,000, 100,000 and 150,000 miles if you are driving under one of these conditions:
1) in heavy city traffic where the outside temp regularly reaches 90 or higher
2) in hilly or mountainous terrain
3) when doing frequent towing
4) uses such at a taxi,police,or delivery service

if you do not use you vehicle under any of there conditions ,the fluid and the filter do not require changing per GM.

That being said, I've seen one come into a shop working fine, but being hugely past its "service by" mileage, needing rebuilt after having a fluid change and filter. The old fluid is so filled with particles of the clutch packs that changing it out causes the transmission to slip like mad, the particles were acting like the friction material in the clutch packs.

What you are hearing is referred to as "chatter," and is a first warning of transmission trouble. If your vehicle has over 50,000 miles, and the transmission fluid and filter have never been changed, the fluid likely has lost its viscosity or has become contaminated, and the internal seals in the transmission have begun to leak. Check the fluid: It should be semi-transparent, the color of blood, and should have approximately the viscosity of lightweight lubricating oil. If it is gray, tan, dark brown, watery, or if it has the odor of kerosene, it bad. Eventually, the transmission will fail.
You may start by having a transmission "service" performed, where they will replace the fluid and filter/screen. If that does not eliminate the chatter, it may be time to consider having your transmission rebuilt.

Chevrolet recommends that the transmission fluid be changed every 50,000 miles, but Chevy intended the transmission to be serviced only by authorized repair shops. For this reason, the HHR does not feature a transmission fluid dipstick. However, the HHR's transmission fluid can still be checked without exotic tools.

It is important to check the fluid level only after the fluid has circulated throughout the transmission by shifting through the gears. Failing to allow the fluid to circulate will result in a false fluid level reading. Turn the engine on and shift through each of the transmission's gears with the brake pedal depressed and the parking brake applied. The car should be allowed to idle in each gear position for approximately five seconds. Turn the engine off, then climb underneath the passenger's side of the vehicle. A small plug is located on the passenger's side of the transmission. Remove this plug with a wrench. Turn the engine on and observe whether any fluid drips out of the transmission plug's opening. If fluid does begin to drip from the plug opening, the transmission does not require additional fluid. Turn the engine off and install the transmission plug.

If fluid did not begin to drip out of the transmission's plug, transmission fluid must be added. Turn the engine off, then remove the black breather cap from the top of the transmission. The circular breather cap twists into the transmission. Twist the cap in a counterclockwise direction until it detaches from the transmission. Because of the lack of clearance between the breather cap's opening and the bottom of the vehicle, transmission fluid cannot be poured into the breather cap opening. Attach a fluid pump to a quart-sized container of new transmission fluid. Insert the pump's hose into the transmission through the breather cap's opening. Turn the engine on, then actuate the pump until fluid just begins to drip out of the plug's opening on the side of the transmission. Screw the breather cap onto the top of the transmission, then install the plug with a wrench.

check ur trans fluid to make sure it is full if low add fluid -look and smell the fluid should be dark burgundy not brownish and should smell like oil not a burnt smell u did not say how many miles or if the filter has ever been changed if it smells burnt or is brownish change filter also if high mileage change also

Every vehicle should have the automatic trans fluid changes at 30,000 miles and never go over
3 years,even if the milage is less.
Also,do the power steering at the same time.

the power steering fluid resevoir is located on the passenger side of the engine compartment near the fire wall. mostimes in order to fill it you have to remove the altenator to remove the fill cap to add the fluid.

Check the transmission fluid level, if that is ok have the transmission fluid and filter changed. Sometimes the filter can fall on the transmission pan and can cause problems. Worst it's your front pump going bad. look for bubbles on your dip stick when checking your fluid and that's a abd sign, Good luck

There is a cap on the driver side down at the middle of the motor see manuel for capacity
