Has anyone ever had an issue with their transmission cooler cracking. Mine cracked in after 2 months of owning the car, Ford replaced the cooler and transmission lines after 3 months of back and forth diagnostics with the dealer. Now 3 1/2 years later it happened again. Ford is willing to replace at a 70% discount, still $5K, but if this is an issue I have a custom option I can go with and for about the same out of pocket expense. Almost 10K miles on the GT, curious if anyone else has seen this issue.
I've done the replacement twice , two different cars. ( a converted 2017 and a 2018. ) Exact same failure . Get the heavy duty cooler from PWR . The problem is the clutch fluid cooler is rigidly mounted with no allowance for expansion and contraction. I oversized the mounting holes and added silicone grommets to allow some movement. I may do a write up of the process. I worked with Blake when he did his replacement.
Ford made a engineering change from a single plate Setrab cooler in 2017 to the two separate PWR trans coolers and did not do any Rubber isolation. The original Setrab set up had rubber isolators. The oil cooler on the other side is a Setrab cooler and it has full rubber isolation on the mounts..
All cars from 2017 that were updated two the two trans cooler setup and cars built to the end of production are rigidly mounted and are more that likely will fail after repeated heat cycles.. My friends 2020 failed and was replaced under warranty.
Would take a few hours to explain all of the repair procedure and post all the pictures of the failures and modifications .. here's a couple pictures of the new heavy duty cooler next to the OEM cooler and the oversized hole with grommets . You can see the cross flow tubes are much larger on the new HD cooler. And for the record We did a really good controlled side by side drive matching speed and conditions and the larger tube cooler has a higher flow and did run a few degrees cooler across the board which was not a surprise.
This curious cat had that suspicion that's why I did the test..
