Tranny Fluids etc...
Anyone know where I can find out what type is neeeded for a tranny fluid ? I did most of the fluids when I got the truck at 92K ( transfer/diff's/ etc... ) but did not do the tranny as of yet ( currently 110K ) ... anyone have a list of what is needed for that - filter, fluid type, modifiers etc...? Thanks !

I thought I remember reading somewhere about recent changes to the viscosity or modifier etc... I'd hate to but so many quarts of the wrong stuff

That procedure could use some updating. MERCON V has replaced MERCON. I now recommoned (as does Ford) MERCON V for this truck.
I also would not use this procedure on a 2005 with a TorqShift transmission. That transmission has a thermostat. If the trans cools below 170°F during the procedure the flow to the coolers will be reduced by 90%. All that old fluid that you want pumped out will be redirected to the pan to mix with the new fluid. Also, a 2005 uses MERCON SP. Do not use MERCON or MERCON V in a 2005!
