I purchase an Aux cooler from my local Pep boys and went to work on the truck


I used some strip aluminum to make brackets. I used self tapping metal screws to secure the brackets


I cut the fittings cooler lines that come off of the transmission at the front of the engine area


I used a dye grinder to cut the collar off of the hose, then used a screwdriver to split the collar open

The half collars in my drain pan with a bunch of other stuff


The trans cooler out of the box


Mounted on the brackets via the supplied quick nylon mounting rods



I used the supplied rubber hose cut in half and just went directly to the lines factory lines. I completely bypassed the factory in radiator tank "cooler"
The transmission cooler also came with 4 hose clamps that worked well with the rubber line and my factory steel transmission cooler lines

 

that looked too easy

im guessing you just capped the lines going into the radiator somehow?

 

While it is a very clean install and detailed writeup, I'd opt for a stacked plate cooler over a tube and fin type myself.. Do you have a trans temp gauge? I don't know if bypassing the rad cooler is really a good idea?? Did you have a factory aux trans cooler?

Mitch

 

The radiator lines are isolated, once drained they dont leak down any pressure from the radiator if that's what your asking

No i dont have factory Aux cooler
I dont have a trans cooler gauge yet

I had this same cooler and same setup on my silver truck with about 20,000 miles on it, just never did a full write up on it

 

Can't argue against first hand experience and if it's worked for you in the past, should work for you now..

I'd be courious on your trans temps when you get that gauge installed...

Mitch

 

Where is the sensor at from the factory?

I think i might put one in the pan when i drop it to do my Jmod for this trans.

 

The computer probably monitors it thru the electronics inside the trans.. Lots of folks get that plug in 'Scan Gauge' setup that plugs into the com port and reads all the temps as the computer reads them..

So, it would essentially be the same as the pan temps I'd say.

I went old school and went the electric gauge route... Actually, I don't think my computer even monitors the trans temp anyway?

Mitch

 

yea ive heard the PCM monitors it, but you can't get the information off of the PCM or something like that.

So you have a sending unit in your pan? Ill probably end up doing a dedicated gauge as well.

 

No, my temp sensor is in the trans output line that goes to the top of the rad. I'm not sure which line it is as it comes out of the trans, as I've not looked that far back and since you don't have the rad lines hooked up anymore, you can't use that location!

I like reading the temp as it's coming out of the trans, as that gives me the hottest temp the fluid is getting at any one point in time. This gives the largest swing of temps on the gauge, but I like that... I can tell really quick if the fluid temp is rising... Pan temps will give you a nice 'average' of the fluid temps, as that fluid has gone past the coolers and has mixed in with the other 6 or so qts of fluid in the pan. Which is fine if that's all you are interested in, but I personally wanted to know the hottest temp. Just like I did for the Water temp gauge I added too. I'm reading that temp as it comes out of the block and just before it goes into the heater core.. The next best place to get the Water temp is as near the T stat as you can, but this was easier to tap into the hose for my sender... But I digress....

Good luck!

Mitch

 

so how much of a bitch would it be to put a bung into the trans pan to receive a temp sensor?

 

I've had a heck of a time with the drain plug I put in my trans pan! It's holding now, but I've gone thru several trial and error episodes to get to this point where it doesn't leak!

You could weld it if you have the equipment/knowledge to do so...

Most folks use the 'test' port that's on the side of the trans. I guess the sender screws right in?

Mitch

 

ahhh ok, ill have to check it out next time im under the truck

 

Hey Pat, are those hoses 3/8" I.D.?

I don't really feel like waiting for my wife to get home to do all my parts chasing.


thanks,
Frank

 

i think so, it came in the box with the cooler

 

I don't know why I just didn't measure the O.D. of the hard line, your pics said it all...

lol...sheesh. my brain was sun-baked.
