First when the check engine light comes on then thats your problem half found .

Let me explain what you should do when you have this light ON and what it means ...

The check engine light can not be turned off, unless the malfunction that switched on the check engine light is first repaired .

When the check engine light comes on this means the engine management system has encountered a malfunction with one or more of the sensors.

In your case transmission malfunction has tripped on your check engine light

When a sensor malfunctions the engine management system (ECM/PCM)
will see this and trip on the check engine light to let the operator know that there is a problem.

If the check engine light does not flash then you are okay to keep driving until you find time to have this checked with a diagnostic scan tool to check for malfunction codes .

From the found malfunction codes you will then know what system has malfunctioned and what to do to rectify this issue.

once repaired then the check engine light can be cleared ans switched off and if the repair was correctly carried out then the check engine light will stay off.

What you need to do is drive carefully to a good local transmission shop .your problem may be just a simple output speed sensor .

First before you do anything is check or have checked the transmission fluid level and condition .if this checks okay then have the system checked for codes .

Please get back to me with the reply button and not the poor or bad service rating , so i can get back to you with further assistance with this issue or offer assistance with another expert .
