I'm in some dire need of help.

I changed the fluid in my 2014 Jeep Grand Cherokee 3.6. I bought an aftermarket pan but used OEM fluid.

The car is now having a terrible time shifting. I opened the weep hole and fluid came out. I also measured how much fluid I removed and it matches how much I put in, about 5.5 quarts. The car has an OEM trans fluid cooler that is using new generic rubber tubing but is the original cooler.

I cannot figure out why the trans wont shift. I get error codes P1D96, p1D8f, P1D95, and P1D90 which all seem transmission related.

Any help would be greatly appreciated!!
