Responding to post from dontcareo:
For an older (70) guy with mobility/flexibility issues, this process still went better than expected. The incentive of buying an $8 part and contributing some time wrestling parts out of my Pacifica was much more attractive than $300-$400 cost at the dealer. Particularly with the complication of not being able to shift out of park and thus not being able to move my car out of the driveway (more discussion on that below for Step 7). After a successful completion, I do have some comments about the steps in the process.
Step 7: After removing this plate, 50-50 hindsight would have given me the view of a pink button area on the passenger side, Pushing down on this button with a screwdriver provides manual release of the shift lever lockout. Then, you could move the shift lever to (say) Neutral where you should be able to start and move the car. With that as up-front info, I may have been able to start the car in Neutral and then limp to the dealer and buy into the dealer cost in a situation with enough urgency. Not knowing that, I plunged on to the rest of the steps.
Step 8: There was no wire cable connection to the second plastic piece. That connector was installed at the rear of the shifter assembly; pushing the top side of it thru an access hole with a small screwdriver allows the connector to be unplugged.
Step 16: The portion of this mated connector assembly plugs into a hole in the base with flexible ribbed sides. This does pull up and out of the base with some simple tugging. Then, disconnecting the front half of this connector assembly from the rear half (with the wires running backwards) is easier done.
Step 21: There was great difficulty in moving the leftside wire cable backwards far enough to free up the "ball" at the end (actually this was more of a cone-shaped crimp-on) securing the wire into the "pink plastic thingy" inside the shifter assemble. What actually worked well was to do Step 22 first for ONLY the leftside wire cable. The anchor/clip)portion for both the leftside and rightside cables each have a small side locking tab that need to be sprung outwards (frontwards) so each anchor/clip assembly can be moved upwards and loose. Then, the wire cable has plenty of slack/looseness to move the crimped end out of the "pink plastic thingy".
The video was very helpful in showing the shifter housing disassembly and then the defective part replacement. In the assemble view, the pink lever used for manual release looked to be activated from the side than from the top (like mine); maybe the ease of access described for Step 7 above might no be possible for all versions (although that does not seem reasonable). The old spring (green sleeve for mine) had fallen out of the shifter assembly and I found it lying loose in the console base. Looking at the old defective part compared to the new replacement, the molded tab for spring attachment was MUCH beefier in the new part. Somewhere along the way Chrysler had seen the weakness in the part and made it stronger. Finally, with my age/weight limitations (and generally insecurity about tearing apart my car), it took two hours one day to disassemble and one hour the next day to reassemble (not 45 minutes). But, as a retired person, the time required was not an issue -- just very glad for a successful outcome.
Thanks Billet Tech for the very helpful instructions.
