Well...Murphy's law strikes again. Just got my 2003 full size Rover back from the head gasket and valve job (nearly $3,500) and was driving great. Out of nowhere the transmission started shifting at a higher RPM than it should have. Within a few minutes I got a transmssion overheat message on the LED display. I pulled over immediately and shut it off...took a cab to my destination and came back 3 hours later. I started her up and drove home no issues transmission shifting normally again. This morning I went out to the driveway and fired her up, within a minute I heard liquid dripping sounds so I shut it off immediately and got out and saw a reddish fluid on our light color concrete driveway which I perceive to be automatic transmission fluid. It was gushing out onto the driveway from the drivers side bottom of the radiator "vicinity." I'm more than certain that the transmission overheat message and this expelling of transmission fluid are related. Could it be coming from my transmission oil cooler or one of the associated hoses? I read that they can get clogged. Where do I go from here? I figure if the transmission is still shifting perfectly fine that I won't need to rebuild/replace the trans...please help I absolutely LOVE this truck but it is acting up so much these days.
