I just replaced the cooler line fittings on a friends 1998 Taurus SE
3.0L automatic transaxle/transmission, because they were leaking (one of them.. but I replaced both). These are the fittings at the tranny. It was not leaking after a short test drive (it was already warmed up in the driveway). However, after he drove it the next day it started leaking again.These fittings are the ones that have the plastic/nylon 'quick connect' and then tread into the tranny housing. I see that there are some tools for the REMOVAL of these fitting (I guess to make removal easier), but I don't see a referrence to any special tools for installation. I need to know if there is a common fix for this issue, other than making a good old fashoined compression fitting for it.
Can anyone tell me what I might have done wrong or suggest a "fix. My first guess would be the plastic 'quick connect' on the new fitting was defective to begin with, but I am not sure. Many thanks in advance and have a grreat New Years Eve.
