good evening and thank you for choosing JustAnswer, its a pleasure
to assist a fellow michigander tonight. Since i am unable to physically inspect the vehicle i will have you check a few things to see if this might correct the concern. Below i have posted the R&R procedure of the shift cable, as well as the cable adjustment procedure, for you to review what you have already done. The concern is still a bit vague for me as it could be either that the shifter and linkage will not engage the gears in the trans, or that the vehicle will not shift out of park. If it is not shifting out of park then first check to see if you have brake lights, if not then likely the brake switch at the pedal has failed. If the concern is that the shifter will not move then first check to see if the shift lever feels 'sloppy' when wiggled, if so then the 2 plastic bushings on the top of the steering column that secure the shift tube will need to be replaced, they only cost $8 each. If the shifter feels tight and the lever just wont move then the cable or the trans lever or cable is binding, or there could be an internal trans concern. First disconnect the cable from the lever on the trans and make sure that the wheels are blocked and the parking brake is on, and with the cable off, have someone move the cable P to 1 or L and observe the cable movement and ensure it moves freely and without much effort on the lever, also check the lever on the trans and (making sure the vehicle is on level surface and wheels blocked ,parking brake on) move the lever on the trans from its rest position towards 1 or L which would be towards the cable's bracket, and ensure the levermoves freely, if so then the fault is either the cable,its adjustment or in the column. If the lever does not move freely then remove the Trans Range sensor and check lever movement again,if it moves freely now the the TR sensor is binding and will need to be replaced, if the lever is still tough to operate then the concern is internal and a shop will need to perform in depth inspecting. Below are the R&R and adjustment procedures for the cable. hope this helps you, please let me know if you have any further questions, i will be online workdays 8-6.

ok, you are referring to what is called the prindle, for the gear indicator. There are 2 cables in the steering column, one that connects to the trans to shift the desired gear, and another that connects from the lever to the indicator on the dash, the prindle has that small black thumbwheel that adjusts the i ndicator. Sometimes the indicator sticks and spraying it with some silicone spray and operating it frees it, or if it does not move at all the cable usualy is broken..
