Has anyone seen the quick connect/disconnector fail before? And by that I mean slide off of the metal fitting lip? Story below if you do not want to read..

I had replaced the torque converter and oil pump in the transmission that I was having problems with. Everything went amazingly well, and the truck is completely different and runs like brand new. Awesome shifting, no slip, etc. Well today I was driving to work and I was at a stop light about a block (idk 500 ft?) from home, and when I went to take off, nothing. Checked various things in the vehicle (ebrake, transfer case drive, transmission drive) and finally decided to just slam on the gas and see if anything happens. Well it started to creep along and I pulled in a parking lot right next to the light. Got out of the vehicle and looked underneath, and transmission fluid everywhere. Turns out, the fluid was coming from the transmission feed line to the radiator, and the quick connect was not all the way on. Simple fix, plugged it back on and filled the truck up with transmission fluid (auto store right next door thank god) and truck runs just like before. I just can't seem to figure out how the quick connector came off? When I removed and installed the transmission, I never touched that part of the line, but only those back by the transmission (starter bracket, at the transmission, etc.) I have went well over 1000 miles since the install and everything has been perfect up to this happening. So what gives? If these things can fail and it wasn't human error (which I can't see it being) I will replace them with hose clamps. Thanks.

 

If it failed once, I wouldn't trust it again...... Did you get rid of the check valve on that line yet?

 

Yup I drilled that sucker out a while back when all the problems started. And that's kind of what I was thinking, if it did it once, why trust it? I've seen others talk about hose clamps work really well, so I guess thats the way to go? Just want it to be simple and easy, nothing complex like I have seen.

 

When I pulled mine out, I just used a short length of trans line, and two hose clamps. It's a pain to get the hose over the lip that the quick connect holds on to, but, putting a clamp on the other side of it, guarantees the line isn't going to slip off.

 

I just feel that it had to be my error before the removal and installation, since those things are tight when I try to separate them. And if nobody has seen them fail, then its most likely me messing up

 

+1... did you use the correct tool? or just pull it apart?

 

i'd replace it.

i used a tubing cutter to cut the check valve fitting completely off the hard line at the frame. i didn't cut the flare piece off the radiator fitting, but you could in order to slide the hose on easier.

then just clamp on a piece of AT hose about 3 feet long. simple, easy, done.

 

Yea I used the quick disconnect tool. I am just going to replace them since I will be installing an external cooler here in the next week anyway. These hose clamps better not fail or you all are to blame!!!!! haha

 

If you're worried about the hose clamp, use an Oetiker clamp instead. Not re-usable but won't come off until you cut it off, and easy to install.

 

A good worm drive hose clamp will work...but stay away from the cheap Chines ones that are very thin. The Oetiker clamps are good clamps, but take a special tool to install the best ones.
