Just wanna make sure i got this right. All i do is disconnect the return line from the original radiator cooler and put the fitting in that which is supplied by the kit. I run a hose from that to the new supercooler. Then run a hose from the line that i disconnected to the other post on the supercooler and im done correct??? Now the bottom line on the stock radiator cooler is the return line correct???? And also just to make sure, there is no need to even touch the supply line right. I want the stock cooler to cool it and then go to the Supercooler. Am i good??
 
yes thats the way i would run it. the fluid will enter the rad. cooler first then it will pass thru to the supercooler and the last line connected on supercooler will be the return, not the bottom line on the stock radiator cooler the fluid will enter at this point.
 
running the fluid thru the supercooler last after exiting radiator cooler will allow fluid to return to the tranny alot cooler than installing opposite just a little added info. to the post i posted above...
 
That is the correct way to run a tranny cooler. Essentially, you are running it in series on the return line. Put the cooler in front of the radiator so the cooler fluid is being cooled first and not heating up the fluid in the stock portion of the radiator. Double check on which is the return line. Usually, the return line will have a fitting so a tranny flush can be done. Good luck.
 
I agree with the in-series after the stock radiator's heat exchanger method. Some people (in frigid climates) like to recommend it backwards, but my take is:
If it's cold out, the stacked plate cooler is going to bypass till the fluid warms up (which your heat exchanger is helping with), so it's not unnecessarily cooling the fluid when the fluid is cold. A stacked plate cooler acts like it has a poor man's thermostat.

I think the AOD and AODE lines are backwards, which would mean the lower line is the return line. Dont go without checking. Loosen the line you think is the return line. Connect a fiting and hose to the radiator's heat exchanger and run the line into a bucket. Bump the starter or start it real quick and shut it down (fluid will fly out if you actually start it - but it might not come out if just cranking). If fluid comes out of the heat exchanger, goes into the ad hoc line you installed and ran to the bucket, that indicates you have the location. If the stock line spurts instead, you got the wrong line. This might all be in your instructions.

Also read up on preferences upon which way to flow fluid through the cooler. IIRC most folks like to have the fluid go into the bottom of the aux cooler and egress (back towards the trans) at the top of the new cooler.



Good luck.
