Have a 2002 Ford Explorer lately when I start and excellerate the cars jerks its almost like driving manual car changing gears as you excellerate. Local dealer said could be solenoid?

A transmission solenoid is a type of valve that controls the flow of fluid within a transmission. Solenoids are used to engage and disengage gears, as well as to control the timing and pressure of fluid flow. If a solenoid is faulty, it can cause a transmission to shift gears erratically, jerk, or even fail to shift gears at all.

It is possible that a faulty solenoid is the cause of the jerking you are experiencing when accelerating in your 2002 Ford Explorer. However, it is also possible that the problem is caused by another component of the transmission, such as a faulty shift linkage, a worn-out clutch, or a low fluid level.

If you are experiencing jerking when accelerating in your Explorer, it is important to have the vehicle diagnosed by a qualified mechanic as soon as possible. This will help to determine the exact cause of the problem and ensure that it is repaired correctly.

Here are some additional symptoms of a faulty transmission solenoid:

* Transmission shifts gears erratically or slips out of gear

* Transmission fluid leaks

* Transmission fluid is discolored or smells burnt

* Check engine light is illuminated

* Transmission makes a whining or grinding noise
