You might have a broken motor mount or broken transmission mount. the motor mounts were replaced one year ago.
Park, reverse, neutral, Drive and low
PRDN stands for "Park/Reverse/Drive/Neutral," which are the different gear options found in an automatic transmission vehicle. These gears control the movement of the vehicle in different ways - park for parking, reverse for backing up, drive for moving forward, and neutral for disengaging the transmission from the engine.
It is the transmission gear selector. P = Park R = Reverse N = Neutral D = Drive 3 = Third Gear 2 = Second Gear L = Low Gear or First Gear Park, Reverse, Neutral, Drive, Third Gear, Second Gear, Low Gear
Park, Reverse, Neutral, Drive, 2nd, and 1st. These are the different gear positions in an automatic transmission
If, by 'reverse polarity', you mean the accidental reversal of the line and neutral conductors at the socket outlet or receptacle, then the answer is no.
Reverse, Drive, Low gears
truck will only go forward not in reverse does this mean the transmission is gone
It means that say you reach a speed of 55 mph. Never shift from drive into neutral (Or a gear into neutral) to slow in speed.
D=Drive, R=reverse, N=Neutral, 3, 2, & 1, are the speeds, or gears,of the transmission. So if there is a problem it is with the transmission.
It means the transmission (or it could be applied to the transfer case, as well) is in a neutral position, not engaged in any drive gear.
There is no such thing as vibrates or non-vibrates. Vibration is a concept when dealing with sound waves. However, one may mean vertibrates and invertibrates. Vertibrates are those that have backbones and invertibrates do not.
