I am planning on adding some additional cooling, but not sure which
option to choose? I am considering an after market aluminum deep
sump/pan or a stock under bed type cooler.

I am towing a 7000 lb. trailor and don't plan on going any heavier.
I am hopeing the extra cooling will help for the time being?

I am planning an on a TQ and a shift kit or valve body in the future $$$$$
Thanks Guys

 

Additional cooling is rarely a bad thing. Unfortunately the irony with the non-lockup torque converters is once you get a better TQ you probably don't need the extra cooling.

 

I pull 5-10,000lbs depending on whether its a boat, calves or hay, etc. I can hit 225* pretty regularly depending on the load and terrain. Its spiked to 250* a couple times under a hard pull. Thats with a synthetic fluid.

I plan on adding a PML deep pan and relocating the temp probe from the dip stick to the new pan. I also have a tranny cooler that I want to mount in the OE underbed location. I bought the truck used so I have no idea if the tranny is original or not but it does OK.

What kind of temps do you get now?

 

Actually a tighter converter creates less heat. I have an underbed cooler and unless im really cranking on it i never see over 200 pulling.

 

Don't waste money on a deep pan until you have an underbed cooler. Adding more fluid just means it takes a little longer to get the trans hot.

 

I have seen temps up to 185 in low, on a long steep grade...
I also seem to be slipping TQ @ 2300 rpm in overdrive? (lot of vibration) So maybe the best solution is to just spend the money on a TQ and shift kit.

I hope hughes will be adequate.

OBTW......My mileage is 12 towing 7000lbs and 16 all around, i am hopeing to
improve this.
My dad's stock 93 CC 2wd does 14 towing and 19 all around.
He also does 70 @ 1750rpm compared to my 70 @ 2100rpm.
(Same 3.54 ratios)

Just curious what rpm are others seeing @ 70 on the flat?

Thanks Guys

 

So very true. The concept that all deep sump tranny pan manufacturer's sell about added fluid keeping the fluid cooler is a misconception. The OEM tranny coolers were not made to cool the additional fluid. Now, when combined with either a Derale or BM tranny cooler w/ fan and T-stat, that extra capacity of fluid will get cooled. My thinking of these deep sump pans has changed; I put them in all my trucks mainly for the added strength they provide because of the raised ribs and because of the drain plug and sender ports. With the cost of tranny R&R I don't know why more people don't make auxiliary tranny cooler additions a priority before turbo upgrades, injectors, etc.
