I did a search for solenoid pack and came up with a bunch of references to people they need to change it, but I haven't found a thread detailing how to do it....like a how-to tutorial. Any body have a link and know off the top of their head the associated cost for parts?
I did mine a few years ago. It isn't too bad, but without a lift it will be a bugger! Then there is the issue refilling the trans.
Drop the pan and the solenoid pack is right there. A few bolts and, IIRC, a hard to reach electrical connector and the old one comes out.
Here's a pic:

Removal and Installation
NOTE: When the battery has been disconnected and reconnected, some abnormal drive symptoms can occur while the vehicle relearns its adaptive strategy. The customer needs to be notified that they may experience slightly different upshifts (either soft or firm) and this is a temporary condition and will eventually return to normal operating condition.
Disconnect the battery ground cable. For additional information, refer to Section 414-00 .
With the vehicle in PARK, position it on a hoist. For additional information, refer to Section 100-00 .
