Hi,

I have a 1998 Plymouth Grand Voyager Expresso, and recently I have been noticing a problem with it. When I accelerate, everything is fine, except for a very slight kick when the speed passes through the 50 mph mark. However, as I am come swiftly to a stop (not sudden braking, but just regular braking) after driving at around 40 or 50 mph, I noticed the vehicle "kicks" and shakes the vehicle for about a split second.

Why does this happen? Is it urgent that I get this problem fixed ASAP? If I don't fix it for another year, will the source of this problem and the shaking/kicking cause damage to other parts of the vehicle?

Thanks.

It is a transmission problem or issue. Have your mechanic check it out, look for low fluid level or perhaps it is a software issue.

Dose the kiks happens when braking only?
If yes does it kiks bak or forward when braking?
If no, have you modify the ride high? Or any job done on your suspension system.
When does your vehicle start to act up?

Thank you for more informations

The kick/shake happens immediately before I come to a complete stop, after I have driven at relatively high speeds like 50 mph. So if I am driving at about 30-40 mph on a major local road, and brake, the kick happens immediately before the vehicle comes to a complete stop at a red traffic light. The brake pedal does not kick. Something else in the vehicle kicks and makes the car shake for like a split second.

Drive no more than 10 mph, and slightly (slowly) apply the brake, does the kick happens?
Does the kick look like wheel lock-up? Or do you think it comes from drive train? Does it kick back or forward?
I'm not thinking about brake kicking at all.
Thanks for more informations

Hi,

When I drove at about 12 mph, then gradually slowed down by pressing the brake, I did not notice any kick/shaking or shudder. However, I did notice that when I drove at higher speeds, such as 50 mph, and then slowed down by pressing the brake, there was a shudder/kick immediately before the vehicle came to a full stop. The shudder/kick seem to be kicking towards the back. This did not happen every time though. It only happened sometimes. Do you think the problem has to do with transmission and drive train?

Please let me know ASAP.

Thanks.

I suspect the non-ABS (Height Sensing Proportioning Valve) on your 98 plymouth.
The proportioning valve controls and limits the pressure to the rear brakes.
Under mild braking, the pressure to all wheels is about the same.
As pedal effort increases , the possibility of rear wheel lock-up exists, only that valve is responsable to prevent it from happenning under heavy braking.
here is your hight sensing-type proportioning valve show in different angles

Certain valves are adjustable, I can't find your is.if you can see a spring that connect the bracket to the lever on the end of the proportioning valve, then it is adjustable on the valve adjustement nut.
