transmission cooling

keep in mind high hp levels build heat in the transmission fast! once the trans fluid temp exceeeds 180 degrees F the trans life expectancy drops, the higher the heat the shorter the expected trans life, trans fluid heat over 220f is sure to hurt the trans after awhile

you can replace the spare tire/carrier with this

BTW your local hydrolic hose supply house can make good high pressure (MINIMUM 200 PSI hot oil (300 degrees F rated) braided hoses with screw ends if you measure carefully.
route it inside the frame rails and away from the exhaust and drive train, up away from the potential for speed bumps and crap hitting the lines

engine oil needs to reach and stay at about 215F-240f
trans fluid I try to keep under 160F,surely below 180F ,Ideally I try to keep coolant in the engine in the 190F-200F range but don,t get overly worried below 230F.I run a 190F t-stat
you can install AUTO temp control switchs and GAUGES (ideal) or manual switchs and GAUGES (FAR FROM IDEAL), your correct that the engine fluids take slightly longer to reach ideal temps, but then they rarely change after getting into the ideal ranges after you set up the system correctly

these allow the fluids to circulate but the fan won,t run untill the temp reachs a set limit



keep in mind the hot engine oil running over the blocks surfaces and trans fluid running thru the lower radiator add a good deal of heat to the coolant in the radiator and removing heat elseware from both reduces the radiators heat load, generally stabilizing the engine temp swings
