RE: Deep Tranney Pan --46RE
Turns out: (1) Removed the torq. converter check valve and replaced it with a T fitting that accepts an an oil or tranny temp. gage. (2) From the T fittingthe plumbing is configured to go to a 11" x 14", 6 pass cooler mounted with (AL) bar stock in front of the air cond. evap. (3) From the cooler oil goes to the lower radiator tranny inlet. (4) From the upper radiator outlet it goes tothe factory oil cooler mounted between the air cond. evap. & the radiator. (5) it then travels to the tranny return line. (7) On the drivers side in front of the air cond. evap. is a 1250 cfm12' X 12" fan that isenergizedwhen the radiator temp reaches 200 deg. F. (the engine termostat is 180 deg. F). (8) The tranny pan has a drain plug. (9) For good measure the fan clutch and water pump were replaced.
Too make a long story short. It seems with or without a trailer, pulling long steep grades causes the tranny temp to be excessive(over 240 deg. F.). When the truck bogs down and the torq. converter unlocks , the tranny temp begins to rise. It seems the only way to control this is to increase the RPMs(3500-4000).On some grades it is necessary to go from 3'rd, to 2'nd, to 1'st and if necessary to 4 wheel low.
Back to my original question.
A recent Summit Racing catalog is advertising a Hughes deep trannsmission pan for a 46RE/47RE@ a price of$186 plus shipping. It claims 4 qt. extra capacity.
Has anyone had experience with this pan(HUP-HP1580+) page 203 in Jan. Feb. 2008 Summit catalog?
Are their other comparable tranny pans from other companies that are less expensive?

I AGREE WITH THE GUYS ABOVE! SPEND YOUR MONEY ON A GOOD COOLER 12X12 OR BIGGER! THERE IS A ONE WAY CHECK VALVE IN THE COOLER LINE THAT SHOULD BE REMOVED ALSO! JUST DONT CROSS YOUR PRESUIRE AND RETURN LINES! IF YOUR PULLING A 22FT TRAILER I WOULD INVEST IN A TUGGER KIT OR A JR SHIFT KIT SOME REDBACK CLUTCHES! I PULL A 4,000 POUND BOAT AND A TRAVEL TRAILER AND IT WILL SLAP YOU IN THE BACK OUT OF EVERY SHIFT! INSTALLING A DRAIN PLUG IS A GOOD IDEA IF THE TRANNY WAS REBUILT BUT IF IT HAS MILES LEAVE IT ALONE!
