For 2005-08 Grand Cherokee Auto Transmission.
I had my blinds disconnect from my shift stick on my shift assembly. I perused through the internet and found very little to help out.
I called the dealer and all you can do is buy the ENTIRE shift assembly from Chrysler/Jeep- which in my area is $700. I saw it online for just under $500, but that is silly to pay for a broken piece of plastic.
Also note there is a service bulletin 21-016-06 REV. A that informs dealerships to NOT replace the entire assembly, but to replace just the bezel... consider that ignored by dealerships in 2010 and beyond.
Anyway- decided to make this post to help people that may have the same issue as me in the days to come- should become more numerous in the days to come. First reference : First read the bulletin referenced above. It is useful for disassembling the assembly: http://www.xkjeeps.com/tsb/tsb_xk_2101606a.pdf
OK- now if you are like me your blinds have broke on the little piece of plastic that surrounds the shift stick- why it is so thin beats me! I tried super gluing it but it didn't hold.
Actually- let me back up. If you are having the limp PRND issue that is common with these jeeps- grab some isopropyl alcohol and swab the circutboard... this definitely helps...
Back to getting the blinds to stay together. So I figured something weaved or elastic needed to bond and spread the force of shifting. What else? Our good friend Duck Tape. I beaded the entire area under the plastic piece and the first few "ribs" of the underside of the blinds, and laid down the tape. Then I cut out the area for the shift stick to move left to right in the housing.
Installed everything and Pow- works better than ever... I did buy it used, but still- managed a $700 part fix for 1.79 (superglue) and some duct tape.
I hope someone else finds this useful.
