H2 external tranny cooler
#12
Hey Citiboy. Im trying to install the same Tru-Cool Cooler on my 2004 H2, and was just wondering if you could explain exactly what I need to cut, seal-off, and which lines to reconnect to the new cooler. Ive been looking for a diagram or schematic, but so far havent had any luck.

Sorry for bringing this back from the dead. Installing this cooler this weekend just trying to get an idea where you cut the lines on the tranny hard lines to install the supplied hose. Anyone that can help i would appreciate it

I just did this install today, I cut one line just under the new cooler, about the midline of the truck. The other line I used an included fitting so I didn't have to cut that hard line.
I went for a test drive, it was about 90 deg. F out and the temp got up to about 125-130 max.
Citiboy or anyone else with this mod have any problems with the transmission temps being too low? I don't want to make a mistake by over cooling the transmission.

Not sure if its a coincidence but after installing the cooler and topping off the fluid a week later and about 100 miles later my trans started to slip....bad. Put a bottle of lucas stop slip and its holding up for now. But i figured i would share

Just installed the H2 external transmission cooler and completely by-passed the radiator internal cooler. Now i don't have to worry about the coolant mixing with transmission fluids when the radiator internal cooler go.
I used this Amazon.com: Tru-Cool Max LPD47391 47391 Low Pressure Drop Transmission Oil Cooler: Automotive
Also, did this:
replaced transmission filter, transmission pan and gasket (old pan we're dented from off-roading)
completely flushed the transmission fluids with oem dexron 6 and reset transmission fluid life to 100% with Tech 2
replaced transfer case fluids with oem dexron 6
replaced front and rear differential fluids with oem 75w90 synthetic gear oil
replaced rear brake pads and parking brake shoes
Serviced front brakes
Need right rear parking brake cable, siezed, parts on order.
Road test result with the new external cooler (about 20 km distance), will update for long term use:
54*C at idle with 90*C engine temp.
65*C at 110 km/hr with 28*C outside temp
I used to run around 98*C with the stock tranny cooler.
I will see if i need to install the by-pass valve in the winter.

I am about to attempt to do this. Any advice before I start? Any complications or hurdles I should be aware of? Also, I want to swap out my radiator. Any suggestions on brands?
