At 16000 miles my 2005 Titan CC SE started leaking fluid. Took it to the dealer - and they replaced the black plastic control unit and tightened the bolts. They drained about 2 cups of blackened fluid full of fine metal shavings out - and refilled with Nissan D-Matic fluid. Said everything is fine. OK - so I drive the truck around for another few months - now have 21600 miles - transfer case is leaking around the drive shaft seal. I brought it back to the dealer again - the unit had run almost dry a second time in 4 months. They changed a seal, put new fluid in and said it was OK. They stated on the repair order that it only took 1/2 quart fluid. I know this is not true because I watched them pull the drain plug - and NOTHING came out except a half cup of black **** with lots of metal shavings. Then they refilled it with 2 1/2 quarts. What kind of game are they playing? - When I questioned this they said "don't worry about anything you are fully covered in case they might be mistaken - and they have never had a failure on a transfer case on a 4x4 Titan pickup. They also said I still have lots of time and milage left on my standard Nissan factory drive train waranty and the truck still drives. I am worried - because I had intended to keep this vehicle for a while and get my $$ from use far after the warranty. I usually keep vehicles at least 6 to 10 years. Please advise!
