code numbers never identify bad parts just failed systems.
you need someone with good diag skills, that can track each code down one at a time.
the 702 is a general trans failure code.
340 is a cam sensor code
1136 is a transfer case position sensor issue.
the fuel rail sensor code may be just that sensor. i have done a few and most of the time, it is the sensor.
dont go throwing any parts at it as most of the time guesses are expensive and mostly wrong.
i would start with the trans code as it is the most vague and may end up with re building the trans.
