4T65-HD
Bought the car in May 2014 with 136k on the clock. It needed a new rear strut or mount so I replaced both rear struts with OE Bilsteins and Moog upper mounts = $800
Lifetime wheel alignment at Firestone = $180
Replaced cruise turn switch, due to accidental high beams = $175.00
Transmission drop replace filter and refill with M1 Dextron VI = $100
Pair of Moog lifetime front hubs & labor = $350.00
Replaced all 4 rotors and pads with Raybestos Advanced Technology & labor $700.00
New plugs & wires with dealer labor = $375.00
Oil pressure sensor = $15.00
Pair of front tires = $345.00
Transimision cooler lines & dealer labor $375.00
So in just under 3 years of ownership not counting fuel and oil changes about $3,400.00 the majority being struts, brakes, performance tuneup. I could have saved myself money with cheaper parts and doing it myself. This car was used for a work sales vehicle for the first 1.25 years of ownership. In less than 3 years I have racked up over 36k miles. The car drives amazing and you would never guess it has the miles it does.
This is a do not attempt 130mph TAPShift pull.
