Question about 2007 Pontiac G6 GT Convertible

Car jerks hard taking off

Car jerks really hard when taking off from a stop. The transmission shifts smoothly otherwise and goes into drive or reverse from park with no problems. The problem occurs when the car is stopped at a red light and you push the accelerator. The car will hesitate then jerk really hard. It is an intermittent problem and hard for an old school car guy like me to diagnose.

Since you\'re old school I would think you\'ve already checked the normal stuff like the fluid level in the transmission. If this is good, has the transmission ever been serviced? I\'m not familiar with your vehicle so if it has a filter it could be that is partially clogged, Does the fluid have a strong smell to it? Does is feel absolutely smooth or can you feel or see little flecks of something in it. You may solve this by dropping the pan and replacing the filter. But if that is the problem it will only be temporary as if there is debris in the pan you are ready for a rebuild.The sooner you do it, the better before you have hard part damage. Another possibility is a bad solenoid in the tramsission that isn\'t sensing the pressure until it is high enough to jerk when it kicks into gear. Again to even check this though you need a transmission guy to pull it and look it over. Sorry guy.

If the transmission shift smoothly, then the transmission is fine and working great. Check fuel,spark plugs ,wires, coil pack and injectors. if they are good the you might have a clogged fuel pump or filter.

Car giving jerks


One of the more likely possibilities is a problem in the transmission. I wish I could be more specific, but I don't know enough to offer more details.

Depends in the mileage since the transmission was last serviced. It sounds like low pressure from the pump. It could be just a filter. You did not say where the leaking seal is, but a leaking seal will not fix itself.

Car jerks when you shift gears


If that oil is transmission fluid, you may be low on fluid. That would cause harsh shifts. Make sure your transmission is full.
Is it just reverse and drive that ****? Do second and third shift smooth? If so, you may have a too-high idle.
If idle is good, and your transmission didn't get low on fluid, then I would suggest you drain and refill the transmission, and install a new transmission filter while you have the bottom pan off. Usually, you can buy a filter and pan gasket as a kit.

I changed the gear box of my 2007 corolla about 5 months ago. Then I noticed the car jerks or kind of pushes forward whenever i change my gear from park/neutral to drive or reverse. Please what do you...


A delay of more than a second in shifting from the neutral to drive or reverse gear, could mean that there is a problem with the transmission. If on changing from a neutral or park position to the drive or reverse gear, the car does not immediately catch the gear and move forward or backward, then it could mean a problem in the transmission. If you change gears, and you hear a sudden clunk or sudden jolt or shudder, then the shifting is not smooth and there could be a problem with the gearbox. If the engine rpm keeps increasing but there is no increase in the speed, then it could be a sign of the transmission slipping.Most automatic transmission systems, nowadays, have a check engine light or an OD light, which flashes if there is a problem with the engine.

When i put my car into drive it jerks forward suddenly and when i put it in reverse it jerks backward also. its never done this before


1. Extremely harsh shifts from P or N, normal shifts at WOT: EPC (Electronic Pressure Control) solenoid failed. Easy fix in pan. Fix as soon as possible or hard parts will eventually break.
2. Shift suddenly become very hard. When going from park to either reverse or drive it slams into gear. 1-2 and 2-3 shifts are also harsh. All gears seems to work. Problem may be intermittent: Check TPS for smooth electrical response. If the response is jumpy or erratic at all, replace TPS.
There are two thing that may be happening that you have described, but you can tell which one it will be since your driving the Blazer. Both are simple to repaire, but to change the EPC. Your going to have to drop the transmission pan so that's going to be a transmission shop and call around, the EPC can be replace the same time there draining the transmission fluid when servicing the transmission which is about $110.00 for fluid and filter replacement and additional $65.00-$80.00 for the EPC valve.
EPC (electronic pressure control) valve TPS (Throttle position sensor)
Thank you for using Fixya and good luck. If it's the EPC failure, replace as soon as possible. may casue the sunshell to fractured or splines to sheared off.
