Q: My truck was running perfectly yesterday, but this morning it won't start.

Hello, a common mistake that people make is thinking the battery may be good because the lights come on. A bad battery may allow power for the lights but not enough power to start the vehicle. The only way to...

The most common problem is the transmission solenoid pack sticks and needs to be replaced. The manufacturer has a technical service bulletin (TSB) number NTB06-005 2005. It calls for replacing the solenoid valve assembly in the transmission.

Hi there. Check the fuel system and see if the fuel injector for cylinder number 2 is malfunctioning. The code P0402 (https://www.yourmechanic.com/article/p0402-obd-ii-trouble-code-exhaust-gas-recirculation-flow-excessive-detected-by-jay-safford) means that the EGR is not functioning and the code P0174 (https://www.yourmechanic.com/article/p0174-obd-ii-trouble-code-system-too-lean-bank-2-by-blake-griffin) means that Bank 2 is lean,...

Hi there. Check all of the fluids in the vehicle and see what is low. If the transmission fluid is low, top off the fluid and see if the transmission stops slipping. If the transmission continues to slip, then there...
