One thing I forgot to mention about the boneyard parts I bought - If you can find an LKQ boneyard near you (They will ship, but drive to the yard if you can) LKQ is one of those breakers that strips the vehicle to the component pieces (like a transfer case or transmission) and WILL WARRANTY the part for a time.
Yea, that time may not be long, but think about this: The 545RFE is designed and capable of handling MORE power and torque than our engine is capable of dishing out, EVEN with Keith's hottest tune options. They hang this thing behind the big monster Hemi trucks and it doesn't fall apart. So the chances are, if the Jeep is capable of driving away from the shop that does the work (provided the monkey installed the filter properly!) then the transmission will probably outlast the warranty period.
Also, a lot of boneyards will know and tell you where the damage on the source vehicle was. The trans is in the middle and behind the engine (I know, duh) so unless the engine took a BIG hit... Chances are that the transmission was fully operational and used to drive the Jeep to the scene of the wreck. It is most likely still operational on all its factory parts. Can you say the same about something that someone tore apart and maybe "rebuilt" with chinese junk parts? Those would outlast a 12k mile warranty too.

If it were me, just like I did before, I would save the money and get the boneyard one that I *knew* was running up until the rest of the vehicle wasn't able to run anymore.
