Had a couple of these, found a couple of broken wires under the floor shifter at the BTSI connector. Here is some info:in some instances, the wiring looms are tangled, causing stress on the wires in the connector at the BTSI. If the BTSI harness is routed incorrectly, it may result in a wire pinching issue because the length of the BTSI harness becomes shorter making it difficult to install. Remove the center console in order to get access to the shifter solenoid. You might have to re adjust the automatic transmission shift cable. Post back with what you find there are several problems that it might be, post back with any other info.
