5R44E pan and cooler lines

I have a 2007 XL supercab, auto trans, 4 cylinder, 2WD. I will be towing with this truck and I want to make sure my transmission lasts. I think that I can swap the transmission pan from either a 4R44, 4R55, 5R44, or 5R55 4 wheel drive as long as I use the 4 wheel drive filter. This is suppose to add some additional transmission fluid capacity. Also, if this true, can I use the transmission pan from an older truck that has a dip stick. I will also be adding a auxillery tansmission cooler and a B&M remote filter.
To prevent leaks from cutting my transmission cooler lines and clamping hoses over the cut ends I would like to replace the lines where they come out of the transmission. What size, thread, etc. are the holes for the transmission cooler lines where they come out of the housing. I intend to use 3/8" Aeroquip socketless hose and fittings.

i was thinking about this on my mazda i never did it though the 01-08 3.0's also use the 5r44e if you can find a 4x4 in the junk yard you could snag the pan from it and use a 4x4 filter i think the 5r55e uses the same pan but im not 100% sure i would also grab the dip stick from the truck you grab the pan from

as far as cutting the tranny cooler lines you dont need to cut them you can get a fitting kit from autozone for a tranny cooler your factory tranny lines run to a tank thing on the side of the radiator get the fitting kit from auto zone disconect the transmission cooler line at the top of the radiator on fitting screws into the radiator and the other goes onto the line you disconected then run your hose and hook them up i did this on my mazda


OR

grab the factory tranny cooler lines from the junk yard off a truck that came with a factory tranny cooler and use them instead of your factory lines you could also use a factory tranny cooler this way it would be better because it bolts up instead of using the plastic holder things that holder the aftermarket ones to the radiator

Thank you for the tip on the Auto Zone fittings.
I have already ordered a Derale cooler, larger than the factory cooler and less money.
I was hoping someone would confirm that the pans were interchangable, what was the last year of transmission dipsticks, and if I would increase the fluid capacity.

last year of transmission dipsticks? they still have them my 08 Mazda B2300 2.3l duratec 5r44e had one and my 2010 Ranger 4.0 4x4 5r55e has one aswell

i think its like a quart more with the 4x4 pan + whatever your tranny cooler is going to hold

you know all of this isnt going to make your truck really able to tow more its just going to make your tranny last long

To make my Ranger tow more I think I need.

1) Better rear brakes - Explorer discs or larger shoes with Aerostar drums
2) Lower axle ratio (4.56 or 4.88)
3) Hold towing speed down to 55 MPH unless passing
4) 2 sets of tires, 1st for off road 31" & 2nd for towing 27.4 stock to 29"
5) Electric trailer brakes - already have
6) Trailer sway control - already have
7) 2" Receiver hitch - already have
8) Electric engine fan to boost rear wheel horsepower - already have
9) Better breathing; intake (K&N filter) - already have and exhaust (Dynomax VT)
10) Better transmission cooling

An A4LD deep sump aluminum pan will fit the 4r/5r trans. It has a finned bottom and adds 2 or 3 quarts of extra capacity.

Your list there has issues. Number 2 and number 4.

The truck needs to be geared for the intended tires. Generally the 4.56 gears work best with a 35 inch tire. If you run the with a 29 or smaller, you will have issues. Like greatly reduced economy and a top speed of around 75. Just a guess on the speed.


I am running a 24k GVWR aux cooler. On the hottest of days in in street traffic I top out around 180. My trans may run a bit hotter from the higher stall speed converter. Summer high way temps are 140ish, and winter temps are just above 100 degrees. I am pulling temps at the pump pressure port which will read the hottest temp with an autometer gauge.

I believe using the radiator cooler warms the fluid prior to the aux cooler.

1)better brakes are always a good idea the stock 9" drums suck
look at upgrading the fronts as well
2)only change gear ratio if you are running larger tires
3)CA law states when towing a trailer you may not do faster than 55mph
4)stay with stock size and 4.10's or go 31's and 4.56's
8)you truck comes stock with a e-fan and a clutch drivin fan ive heard talk of people removing the engin drivin fan and getting a programmer to change the temp the e-fan kicks on at plus a few extra horses is always good

how much are you planning on towing with this thing?

My trailer is a Casita (somewhat more aerodymamic than other brands) It has a GVW of 3500# but when I scale it during camping trips it is always 100# or 200# below 3000# and assuming 10% tongue weight.
I have been using a F-150 to tow; but liciencing and insurance costs and the problems involved with changing licience and insurance back and forth as I camp have become a problem. I want to use the Ranger to tow the Casita. I now have 28" tires on the Ranger and without a trailer but with my wife and I aboard, a full tank of gas and a moderate amount of camping gear the automatic downshifts from 5th to 3rd gear on even the slightest of inclines. I think I should get 4.88 gears and If that turns out to be too much even when my speed is restricted to 55MPH when towing, I can go to a larger tire (235/75R15) for towing. The other use I have for the Ranger (besides city driving and towing) is running back country roads in Baja. I willl be using 31x10.5x15 tires for that and my city driving; both of which are again not 75 MPH expressway driving. I am inclined to go to 4.88 gears especially when I see that the 2.3 engine is rated for maximum touque at 3750 RPM and the 4.0 reaches maximum torque at 3000 RPM. But this is all reading and no practical experience. As to bigger front brakes, are you suggesting EBC pads and power slot rotors or is there something better?
