Told to drive in 'Power' mode?

[jixel 78]

All LE BTR autos run in overdrive in power and economy. The reason the suggestions are made to use power mode after a trans service is to try and protect the lock up clutch in the converter,because time and again the converter is the first clutch to fail. They still go into lock up, but at a higher speed.When the converter goes in to lockup(usually 85-90 kms)it is in effect closing the converter which is direct drive through the box to the diff with no slip.At this point,the BTR shows up one of its flaws,which is the weak point in the converter clutch.It gets more load in economy because it comes in at a lower road speed than it would in power mode, causing heat.He probably said these things to you because experience told him the oil that came out of it was very contaminated and after servicing and driving it he would have thought `this box is pretty loose,its probbly going to fall over soon, and I`ve just serviced it,so hes probably goin to blame me. Better tell him to be gentle on it`Sorry for the drawn out post. Been with Ford for 20 years. Seen heaps of it.
