Transmission Cooler Hose keeps popping off

So the line from the tranny running to the transmission cooler has now popped off 4 times in the past year, spilling all the tranny fluid in the process.

The first time the compression fitting just popped off...stuck it back on and was good to go.

2nd time, the fitting failed and wouldnt go back together. Cut off the fitting and doubled up the hose clamps, it popped off again. Put it back on with the tube flaired this time. Was good to go.

Now it just happened for a 4th time.

Now I have two hose clamps, on as hard as they can be, as well as the tube being flaired...this is getting fairly expensive for just tranny fluid.

What can I do to keep it from coming off again??

no idea, maybe if it happens again just replace all the hoses. Hoses will stretch and form to a larger size over time.

If you replace the hose make sure you get one that is for ATF. Hoses for fuel are degraded by transmission fluid

thers a kink somewhere and it builds up pressure and blows off at the weakest point.

Yep, have you verified that the cooler is not plugged completely or partially?
