Hi, I need to replace my transmission oil cooler pipes but can't get them off the oil cooler... I fear that they will break.. Who knows of any aftermarket oil cooler??

 

I've taken them on/off radiators several times, I believe an adjustable crescent wrench was the tool of choice with some PB Blaster oil. On using an add-on unit, there might be an issue as there is a tranny heat temp sensor on one of the oil cooler lines, and the tranny oil is warmed up by the radiator. That temp sensor inhibits overdrive until tranny oil gets above 150. If you only have an external cooler, that could be a problem in winter. Of course on the Disco 1, there tranny lines are on the driver side and the engine oil cooler lines are on the passenger side (found a good looking radiator on a Disco that had been killed by blocked oil cooler lines - had to return it).

 

It helps if you put your vehicle info in your signature. For all we know, you could be looking for pats for a Kia...

 

Isn't the tranny cooler the little round one in front beneath the grille?

I had to replace one of my cooler lines due to a pinhole leak it sprung. That was my first repair on my "new " Discovery.

 

Yes thats it.
I only have that one... I don't have any tranny pipes going to the radiator.

 

The front tranny cooler (horizontal unit in front of AC condenser) line on the left side runs back and up to the upper connection on the radiator below the upper hose. So we are both right, it has both. Guess the radiator warms up the tranny to 150+, and the front cooler keeps things under control when towing. In the RAVE workshop manual there is a drawing on section 26 page 5 that shows this. Lots of pickups don't have a tranny front cooler, and just depend on the radiator. So you might be able to use one of those after market ones.
