This came up in another thread so I thought I would post an FYI. I've had two tanks were I've been fishing about 20% of the tank and the transmission has started to complain a little. Although that only works out to about 150-200 miles when I move it in to gear now it klunks and when it cold it take about 15 sec for it to engage. Both new symptoms. Once it warms up there is only the klunk. So I'm hanging up my rod until the transmissions goes then will see about a 5 speed.
