Transmission Gear Slipping problems of the 2008 Dodge Nitro

4 big things wrong: first, the fuel spills out onto the ground when filling it up at gas station because it does not click off. I am always in a hurry to leave the gas station so no sparks ignite the fuel on the ground and then blow up my truck. Second, there are electrical problems. None of the inner dome lights work and the passenger headlight has a short in the wiring. 3rd, the heater stopped blowing through the main vents and also it gets cold then hot then cold again. The temperature on heater wont stay warm. 4th:the transmission is slipping and wont run right. It will not move when gas is pushed then after a few seconds it will kick in and go. Then it slips between gear shifting. Its an automatic.
