So I got my 2001 T&C going again. With the part-time job I have in delivery I have to drive the van very very hard. My previous car was a Prius and I did a lot of passing a lot of flooring. I want to get this van ready for severe use. It will stay on for 8 to 12 hours a day.I have a small time window to complete deliveries and have to go on steep hills and do A LOT of passing. I'm surprised this car can even pass So today I hit WOT about 6 times.The engine has been good but I'm a bit worried about the rest of the car. The transmission does not feel right if I shift over 3,500 RPM. I turn off the AC if I know I'm going to go over a 4,000 RPM just to make sure it doesn't blow up. I also hit 3/4 throttle after second gear to avoid ware. The van was not used like this before. I'm using full synthetic oil. Is there anything I can do to not blow the car up? This car has a power steering and oil filter cooler. It will burn oil fast when I drive hard. I'm am getting a better transmission later so any good brands you recommend would be appreciated. I'm open to looking at better tires with better grip. The ABS is not working on this car at the moment. Does anyone have any experience with taxi service/ fleet use or some kind of severe driving with this van?
