I had my diagnostics plugged in to help with m and s lights and they came up with " cams time out " and " can time levelling " anyone know these as I dont want to waste more money

Those would be CAN codes (don't be dragged to another area by "cam") -

From the RAVE:

Software in the EAT ECU monitors hard wired inputs and exchanges information with the ECM on a Controller Area Network (CAN) bus to determine gear shift and torque converter lock-up requirements. Resultant control signals are then output to the gearbox solenoid valves.

Those codes are from the tranny ECU, which talks to the main ECU constantly over a network. So you are probably in limp home mode, poor shifting, etc. Could be module, grounds near it, voltage problem (battery needs to be 100%), wiring issue, etc. Not sure if XYZ switch full of water and mud could do it, but you can check that for grounds also when under the truck with a meter. Basically the tranny ECU is having a hard time hearing the main ECU.

RAVE has color coded wiring diagrams, and here are a couple of pages that describe the codes and the info that the transmission finds to talk about with the engine computer constantly.

What are the exact fault code numbers, this will help us help you.

If they are 1842 and 1843, those are CAN error codes for the transmission, and have text message that is similar to your post.
