Transmission Dipstick Problem

[Gregory OConnor]

Eric, one other part that fatiques often in the 3208 is the oil
pickup in the sump. I was surprised when Cat had the part instock.
The clerk said it was a high failure item. The truck had 300,000+
miles whin it failed on me but record from the previous owner showed
it was repalced twice prior when the pan was dropped.
