Hello,

Ok, your tranny is stuck in what is called Limp Mode, here are possible causes.....

In-Put/Turbine Speed Sensor Failure

and/or

Out-Put Speed Sensor

or the

TCM - Transmission Control Module

next would be the tranny itself - the front pump failed or internal damage.

Changing out the 2 sensors is the cheapest and easiest first step cost of about $35 for both.
