Transmission went out at around 44000 miles. Dealer said the "lip seal" failed inside transmission, after taking it in several times for diagnosis. Would not assist with repair cost. Ended up having it repaired at aamco. A/c is currently out on the low setting (#1). Not yet repaired. Just repaired the cooling system. Dealer said it was an internal leak. Van kept getting low on coolant, had to keep filling it up, however never saw a leak. Dealer said problem with the manifold, and coolant was leaking thru and being evaportated, therefore no telltale leak. Cost $600 to repair (at 53,000) miles. I hate this van. This is the worst one I've had. Unfortunately, I did not buy an extended warranty.
