Electronic Auto Transmission ECU
	
	
		Sorry to hear about the swim. I did the same (without the water ingress into the engine). See one of my posts. 
 
Auto went into limp home mode and I replaced EAT ECU (from Truimph Rover Spares - paid just over $200 for it) auto was still not right. XYZ switch cleaned out of water to no avail, also looked at O2 sensor which was ok. Had to freight car to Perth from the Pilbara...  I removed the trim guards and put tennis balls under the carpet to allow the sound deddening rubber to vent and dry (it was also over 40DegC which helped though).
 
After 3 weeks in Jordan Rover Tech in Perth it was discovered that the EAT ECU loom was full of water and shorted the replacement ECU. I had all fluids replaced, loom replaced, EAT ECU replaced again and gearbox and diffs filled with Red (anti vibration fluid). Jordan Rover Tech very good if your in WA.
