Default Need help on the transmission cool lines

Hi ClubLexus,

I noticed the transmission oil on the drive way, so I look for the source of the problem. It seem coming from the hoses connect to the transmission cooler. I had the transmission cooler installed by SRT in Beltsville, MD by Moe a while back (2008 I think when the car had 80K miles) when I have the 2800 PI torque converter installed. My transmission went at 155K miles last year. So I replace a used transmission. I did not put the PI torque converter back on the used transmission, because I think that was the cause of my transmission failure.

Long story short, I want to remove the transmission cooler and reconnect the transmission lines back to the way it was. I have a few problems

- The transmission cooler attached to the radiator with these square plastic thing, circle in red

How do I remove those squares plastic? Cut it with knife?

- From the bottom, I can see the transmission lines (circle in red). If I disconnect these hoses from the transmission cooler, then where do I connect them to? To the sticking out things near the bottom of the radiator (mark in red rectangle)? From which hose to which connector?

Thanks ClubLexus,

OK, I am seeing the oil is coming from the bottom of the radiator. I need to remove that transmission cooler in order to investigate further. Any help would be very appreciated.
