Mine does that sometimes and I'm wondering if the fan has anything to do with it.

detontation in a nutshell is when your motor runs at a higher tempurature than normal (combustion chamber) and the exhaust valve gets so hot that it actually causes the fuel-air mixture to ignite before the piston gets to TDC.

if your engine makes a pinging noise than it could be detonating at the wrong time. if it was detonating wrong than i dont think it would do it at 1800rpm more like at 3000rpm and above.
it could have to do with the tranny if it only happens with the O/D off. i would have the tranny drain and looked at by a trans guy you trust. have the rear end fluid changed.
