check the linkage and possible a bad tranny mount..read up on how it works Everyone should have a manual for their vehicle, and the library should have a professional shop manual available, for FREE, in the reference section(make copies of the correct sections) read up and fix it like a PRO! :) good luck-Dave
A transmission that shifts through gears after moving lever to "d" without driver doing anything no clutch pedal
yes
An automatic transmission is a type of car transmission that shifts gears on its own. Therefore, cars with automatic transmissions will not have a clutch pedal and will have a selector lever as opposed to a shift knob.
The year, make and model info would help.
A mongoose shifter consists of a lever, linkage, and transmission. The lever is used to change gears by moving it back and forth. The linkage connects the lever to the transmission, allowing the driver to shift gears smoothly. The transmission is responsible for transferring power from the engine to the wheels, enabling the vehicle to move forward or backward. Together, these parts work in harmony to control the speed and direction of the vehicle.
Lubricate all linkage parts and check for bent, misaligned or worn parts
In a manual transmission vehicle, jumping gears involves moving the gear shift lever to change the gear ratio, which determines the speed and power of the vehicle. This process requires coordination between the clutch pedal, which disengages the engine from the transmission, and the gear shift lever, which selects the desired gear. When shifting gears, the driver must match the engine speed with the vehicle speed to ensure a smooth transition and prevent damage to the transmission.
put petrol in it
The shift cable for a 1998 Ford Expedition allows the transmission to be shifted throughout the available gears. It is linked directly from the shift lever to the side of the transmission.
Usually either Park (P) or Neutral (N). Pretty much any car will only crank in those gears, and even if the car could crank in other gears it would probably damage or destroy the transmission
The gear shift lever mechanism in a car allows the driver to change between different gears, which control the speed and power of the vehicle. When the driver moves the gear shift lever, it engages different gears in the transmission, which in turn changes the speed and torque of the engine to the wheels. This allows the car to accelerate, decelerate, and maintain speed efficiently.
When the transmission lever is in 'Park' it activates a small rod (known as a "pawl") that slips between the teeth of the transmission gears and locks the transmission at a standstill. It is possible that through age (or mis-use and abuse) the pawl may have been bent or broken (e.g.- someone tried toput the vehicle into 'park' while it was still moving). If you're lucky, perhaps the rods running from the shift lever to the transmission have gotten out of adjustment (or bent) and the lever is unable to activate the pawls action.
