Transmission oil cooler
Most of the parts for adding an aftermarket auto transmission oil cooler have arrived:
13 row oil cooler, hose and some (but not all) of the connectors - still waiting on 2 x 10AN female to 6AN male reducers (those 90's and hose are 6AN and the fitting on the coiler is 10AN) and also waiting on 6AN male to 8mm barb connectors (x 2) for connecting the hose to the gearbox.
The setup will be gearbox out to oil cooler in, oil cooler out to stock oil cooler pipe so only disconnecting one line from the gearbox and leaving the standard return line as is and running in series with the stock cooler not replacing it.

Re: Transmission oil cooler
You don't wanna run 5/16th hose! Hole lot easier to just get hose clamps etc.

Re: Transmission oil cooler
I added an ATF cooler to my Verada 5 speed auto.
To be honest I suggest you line it up the way I did:
Transmission out --> Factory cooler (radiator --> Thermostat bypass valve --> Auxiliary cooler --> transmission in
This way the ATF warms up if too cool, and if within operating temperature it bypasses the external cooler and goes back to the transmission, if too hot it goes past the external cooler and then back into the transmission.
Make sure you mount the external cooler on the side of the fan that starts first.
Since the ECU controls the fans (this may be different on an FTO) it activates 1 of the fans first, and if coolant temps go too high it actives high speed and/or the second fan.
This is also the fan that activates when the A/C is on.
What I am now looking at doing is getting a thermo switch to activate the fans if the ATF fluid rises too much.

Re: Transmission oil cooler
I'm going to have to get one of these... My new radiator didn't have trans cooler connections so it's just plugged up for now... Hot weather will be a different question

Not sure if you are referring to my post.PHIL069 wrote:Nice work.

If so, here are pics of the external cooler. To be honest I fear that it is mostly covered by the front bar and unsure of how well it's cooling. When the fans kick in there is lots of flow over it. When they don't work I am not sure

Re: Transmission oil cooler
Are the 2 metal straps holding it on?

Re: Transmission oil cooler
trans coolers bypass cooling when cold anyway?!
