i've got a tranny cooler sitting in my garage but i'm clueless as to which lines are which, i found the 2 coming off the tranny to the radiator but i dont know which one is in/out, i'd like to put the cooler after the radiator so it goes tranny-radiator-cooler-tranny. my haines and chiltons manuals are worth fire kindling on this

That's it. You can either cap off the line running through the rad and replace it with the cooler, or just run the new one after the one in the rad.

You can delete the in tank cooler and run lines straight to your ne cooler or you can plumb it in 'series' with the existing cooler.....

i'd like to... but which bloody lines are which?!

If you have an assistant, this method works to figure out which is which on any car. Unplug one of the lines, have able and willing assistant start car for just a few seconds. If the fluid is flowing out of the hose, it's the inlet hose. If it's flowing out of the radiator fitting, then you have the outlet hose. (This is the where to tap in.)

Just let it run long enough to see whcih direction the fluid is coming from.

I did say 'in series', which means it makes no odds if you pipe an extra cooler into the intake or return of the existing cooler.....It will still take out the heat....

would you recommend taking the stock one in the radiator out of the loop all together as opposed to the series method?

Not where its cold,the trans fluid needs to be at optimum temp...re quick warm up.
