Seemed like a great deal and I was cautious as we hadn't planned to replace the Patrol for another 12 months, but the heart gave way with encouragement from the family. We took the extended warranty, had the service history all looked great until 3 weeks later 120Kms into our return journey home warning lights aglow all over, into limp mode, eventual shut down just off the freeway. In short, 2 x JLR dealers failed to locate the cause as there were no relevant fault codes apart from the warning 'transmission overheating". With the support of friends in the 4WD community & fellow LR owners I located an ex-LR mechanic (not a technician!). After some angst our concern was damage to the transmission so off to a highly regarded Auto Specialist who diagnosed the issue immediately. An almost collapsed heat exchanger. On recommendation this was removed from the circuit & a direct transmission cooler installed, with not an issue since.
Thankfully not any damage to the transmission......:thumbsup::whistling:
On contacting the dealer & the extended warranty company, the cover is for "Mechanical Failure only" which the cooling circuit was not listed as being covered.
I concur that if towing beware of the TC cooling issue, and have the transmission serviced earlier particularly if travelling in the dusty outback. Whilst this is not a common fault, it is not unknown among transmission servicing companies and is prevalent with vehicles towing frequently.
