How many miles are on your car? It's a 3.5 V6 engine, should have lots of pep, unless the transmission is damaged? Are you a taxi driver? Seems like you might be from your name above?
Maybe you have been OVER LOADING your vehicle? Did you consider that? Not sure, but, even if you had purchased the extended warranty, they might not cover it for commercial use. I think you have a transmission problem? Did you have that checked out?
If it is the transmission, it will cost thousands of dollars to repair/replace. Don't get an exchange transmission, they are garbage. My advice is find a reputable independent garage that specializes in transmission work and have the install a heavy duty unit with a transmission cooler. Otherwise, go get yourself a Mercedes Benz Sprinter with the 3.0 V6 diesel engine and 5 speed transmission. They can go 500,000 miles or more. You need it in your business. Good luck.
By the way, the Sprinter is expensive, but, your in business, it's a write off. And, the vehicle with the diesel engine gets phenomenal mileage for a vehicle as large as it is. That thing is so powerful, you can even tow a 5,000 pound vehicle behind you, not that you would, but, that will give you a pretty good idea on how much power these things have.
Is it possible it could be a leak... or the pan is damaged.......
