I got front accident in my 2015 jeep cherokee 3.2L limited , And that caused to broke the transmission valve body and the TRANSMISSION RANGE SENSOR, and the main power wiring that come from the battery been cut off. I already bought them from ebay and replaced them & re- wiring the cutted wires .. But unfortunately after the installation, The transmission did not work properly very slow response ( gear 1 , 2 & Reverse rear is not responding ? on the scan tool it did not show any code ,
So would your guys please give the solution for this problem ? and if any one has the wiring diagram the support the transmission ..

Many thanks in advanced
