My 2005 grand cherokee had the real seal leaking. When I took it in for service, they "found" the transmission seal leaking and fixed that also, this was not noticable prior to me taking it in. The next day fairly large muddle of tranny fluid on the ground. Now the Tranmission adaptor plug needs to be replaced. Thankfully I bought the extended warrenty when I purchased the vehicle and only had to pay a $100.00 deductible. Had a 2000 grand cherokee with 156,000 miles and the only problem was a fuel pump!?!? What happen?
