Lifetime Powertrain Warranty Nightmare

We have a 2008 Chrysler Town & Country (169,000 miles) which now need a new transmission. We have a Lifetime Powertrain warranty and brought it to the dealer. Dealer have had our van for 5 weeks waiting for approval from Chrysler, said there was nothing they can do but wait. Now they say Chrysler wants electronic images of the transmission to see if there was neglect, dealer said we'd have to pay over $600 for these images

First of all I feel like it's costing us $600 to help them to find a reason to deny the claim. Second the dealer said they also may deny it because the cost of the transmission will exceed the value of the van. From what I can see there is no mention of the value of the repair exceeding the value of the vehicle in the actual factory warranty. I feel if they want to buy out the van then that is not honoring a LIFETIME WARRANTY because they are deciding the end the lifetime of the vehicle.

Has anyone had any experience with this. It is impossible to get anyone on the phone at Chrysler except low level customer service agents who do not know anything and cannot transfer you to any supervisors. The best they can do is send a message for a call back but no one every calls back. So frustrated with this whole experience that we will never purchase a Chrysler again.
