Hey guys...on occasion my car will make a jerky feeling on teh accelerator, kinda like it's either in too high of gear for how fast i'm going and its trying to catch up, or like it's going to stall feeling...almost like it's gasping for air, if I hit the accelerator it goes away immediately, no loss of power nothing...it happens when i'm driving either triptronic or auto...i'm def. in teh right gear no doubt and it happens when i accelerate and then let off the pedal a little bit...anyone experience this?

Acura 2004, AT...only Mod = AEM CAI

 

it happens on all new TLs. My guess it is how the transmission was built because of the power of the engine being too powerful. My guess is that they built the transmission to downshift after you get to about 40 mphs and then at 25 mphs. It happens with my TL too. I brought it to the dealership complainning about it but they give me an older 06 TL and it has the same problem. Somehow hondas V6 transmission don't have the problem, but acuras do. I guess it's shit for a luxury car to do that but I test drove a mercedez before and it has the same problem. So don't feel bad about it.

 

that does make me feel better...wish it didn't do it...but if they all do it, then it is what it is...thanks.

 

It is the car staying in gear, acura's are programed for a bit of more engine braking than hondas, and well engine braking occurs when the transmission is still engaged to the motor, thus causing this feeling.

 

Quotes from Acura -

"When in automatic mode, the transmission incorporates an advanced Grade Logic Control System and Shift Hold control, which work to reduce gear "hunting" and unnecessary shifting."

"To cut down on unnecessary shifting when negotiating winding roads, the Sequential SportShift automatic incorporates improved logic called Shift-Hold Control. When the throttle is suddenly released and the brakes are applied, as is the case when decelerating at the entrance of a corner, Shift-Hold Control keeps the transmission in its current (lower) ratio as it negotiates the corner and accelerates out. This feature leaves the chassis undisturbed by excess shifting, and ensures that abundant power is available without a downshift at the exit of the corner."

From me -

Although the Acura statements says "When the throttle is suddenly released and the brakes are applied", I get it to happen without hitting the brakes (I think). By just quickly getting out of the throttle after WOT in lower gears, I get it to happen.

 

damn guys...thanks for the responses...glad I posted up rather than go through the hassle of taking it to the dealership!

 

I am getting weird rattle or shifting problem when I accelerate to about2krpm or 40 mph.. usually happens im going up an incline. is this the shift hold control.. or is this a bigger problem?
