Took the beast to bunyip today and she performed extremely well until my confidence kicked in an attempted a big bog hole. Water coming in the front door etc. Until I got snatched out. After many attempts to get out, once I was out the a/T check light came on and then it seem to have gone into limp mode. I switched the car off hoping to reset the computer. Bad mistake. Car would not start, after multiple attempts to reset the computer by disconnecting the battery it finally kicked over but was still in limp mode. I drove it home to Cranbourne North and watched the temp on the transfer n seemed to stay at a reasonable temp. The car seemed fine to drive home accept that it was in limp mode. After getting it home I gave it a quick tub so it's easier to work on and then sprayed every electrical point with crc. I also disconnected the battery for over an hour but still won't start. Turn ignition and all lights come on and you can here the power running. The a/T check light still comes on. Could this b a computer fault, fuse or automatic position switch. The car has a built auto in it with a f250 super heavy duty transfer cooler. Please help as this seems like something pretty simple and the car seems to run fine when it's running
