''Datamaster'' can also read the trans temp.Even though it's not common knowledge a 4L80E(not sure about a 4L60E)has a sensor in it that will read the temp.I've used my laptop connected to the diagnostic port to monitor what the engine & trans are doing.As far as I know there aren't any kits to access the wire that goes to that sensor,I wouldn't want to mess with that wire anyway.What sensor is used for transmission temp when checking with a scan tool? The one on mine seems to be accurate.
