Solenoid Pack Replacement 99-04 Jeep Grand Cherokee 45RFE P1781 Fix P0700

My 1999 JGC started going into limp mode last winter with a P0700 code. Auto Zone helped me pull the P1781 code from the computer and after all my research this was my solution. If I shut my car off after a few miles and restarted it would work fine. I researched a ton, thinking it could be the TCM, the battery terminals, or the speed sensors. Turned out to be a bad solenoid pack in the transmission. Here are all the links and info I found in my extensive research. Turns out this wasn't all that uncommon a problem. But I couldn't find a video! It's been 6 months since my DIY fix and no problems! Shop wanted $700 plus the price of the part. I spent $200 on a refurbished solenoid pack and another $50 for the filters and trans fluid. Took half of a Saturday and saved me hundreds, and I'm no mechanic. Here's a copy and paste of all my research & links. Good luck!
