Ok it could just be your quick connect fittings, so don't panic! My 07 was leaking at the quick connect fittings on the transmission side. The two fittings were under 20 dollars for both from the dealer. I got a quote from the dealer ship to fix it and it was around 100 dollars. It probably took 10-15 minutes to pull the lines off and replace the fittings. Very simple job.

That's a lot of money to replace a simple part. Just for future reference, the transmission operates under fairly low pressure. Most aftermarket kits simply use rubber lines and hose clamps to secure them. You can easily fix a busted metal line by cutting out the split part and reconnecting it with a rubber piece and some hose clamps. If you have a flaring tool that is recommended. I had a '99 Grand Prix which is similar to the Impala for those years. The tranny line rotted out right where it goes under the radiator. I took a tubing cutter and cut out a 2 foot section of rusted hose and replaced it with a rubber hose. Never had a problem.

But the proper parts really aren't that expensive, no reason to go rednecking like that

Well I'm not sure how expensive those lines are but I'm going to say around $50 (don't quote me) but i will tell you that Ford uses the above method for their transmission lines on their big trucks, rubber line with a clamp over a metal line. What can I say, it works but it isn't pretty lol.

It's called a transmission cooler line fitting, they are a dealer only item. To disconnect them, pull back the plastic collar, and carefully pry the little spring clip out with a small flat blade screwdriver or pick tool, then pull the line out. After that you just unthread it from the tranny. Remember, the two fittings are different, the dealer will need to know exactly which ones you mean.

I just fixed it today it was something as simple as buying 3$ clamps the original clamp was no longer holding the rubber hose on to the medal part of the line coming from the radiator .....and my mechanic was trying to charge me 350$ to replace the whole line sure am glad I didnt go with him

Who should have replaced leaking fittings

I had a new radiator put in my 2002 impala in January of this year...$300. The shop told me cooler lines were leaking and the tranny was making a funny noise when idling (which I knew about the noise as had them look at it) In February I had a rebuilt tranny and new cooler lines put in...$2500.00. A few days ago the tranny jerked on take off like it wasn't in gear. Took it to the tranny shop & they informed me the cooler line fittings were leaking. WTH...!? Which one of the shops should have replaced the fittings? I believe one if them spoke have been responsible enough to do so rather than wait 8-9 months for this to happen. Thank goodness guess nothing else was damaged but it's another $100 now

No warranty on the work done? I wouldn't have paid a dime to them

They obv didn't torque it down good enough or something
