Please ask the seller if these liners are the reinforced ones. They might be selling you the older model liners and these will give you the same problems as what you have now. To make sure, you might look for the 2008 or 2009 liners since I'm pretty sure these have been corrected and is a direct fit with the 07's.

RCHILL mitsubishi is a sure bet seller on ebay although I'm not sure how much more they will charge for the liners.

There's a link here on the forum to download the service manual for the Outie. You will get all the information you need regarding the placement of the tranny cooler.

Good Luck!
