2003 galant surging while foot is on brake

When ever I am at a stop light and holding down the brake, my galant will surge. If you can imagine a dog barking and then lunge at something that is the same effect. I was told that this can be due to a possible thermal breakdown of the transmission fluid. this problem can be fixed by flushing the transmissions fluid and then refilled with revised fluid. is this true? and if so, how much would this cost me? I am very worried.

It could also be a problem in the power brake booster valve too (It could be many different things, however tranny fluid is not on my list).. Is the tachometer surging or dropping as well more than 200-300 rpm? How many miles are on the car and or the tranny fluid?

What caused my Lincoln ls to surge while foot was on the brake?

My 1st guess or 1st instinct would be to say it's a computer software issue, becasue I can't think of anything mechanical that could cause this type of issue. I suggest instead of asking here, you contact your car dealer or manufacturer.

When I brake the car surges. Feels like disks are warped but has recently had new brakes. This started surging about 8 months after the brakes were replaced. Could it be the fuel pressure regulator??

If the vehicle only surges when braking sounds like you have a brake pulsation. If the brakes have become overheated like when driving down a mountain this can warp the brake rotors. They will need to be machined or replaced.

Car surges when stopped at traffic light or stop sign. This is a 1998 galant.

You are probably having problem with your Idle Air Control Valve (IACV). It can rev your motor up to the point where you are driving down the road at 40-50 MPH with out touching the gas pedal. Fortunately, unlike that other brand,you can use your brakes to slow back down. If the new part is too expensive($435 on the 2003 Lancer) you should be able pick a good one up at the salvage yard cheap. The IACV for most cars new sells for $25 to $50.

2008 Ford Edge engine surge while stopped in gear

Sounds like a faulty Throttle position sensor. Warranty should pay for parts & damage, talk to your dealer. The 88 -90 ford tempos had same problem & a driving school was using them, lots of kids & instructors got the heck scared out of them, but luckily no-one injured badly.
