Transmission Cooler
This morning i started my truck up. It was about -20 and 7 am. I let her warm up in nuetral. Well anyway i came out, hopped in and put her in reverse.....nothing. Then in drive.....nothing. I put it park and walked around the truck and i could smell tranny fluid. I couldnt see anything under my tranny so i walked to the front and checked under neath.
Thats when i noticed all of my transmission fluid all over the ground.
So i shut the truck down and had a look to see where it came out. The return line from the aftermarket transmission cooler had popped off. I just had the tranny fluid changed 3 months ago along with the filter. Why would it come off? It wasnt even loose.

was the clamp still on the end on the hose ? was it one the the screw clamps, maybe it just falied.
some shop do a trans fluid flush. where they disconnect a line and connect a machine in place. if they stressed the clamp or did not get it on the line "over the hump".

There is usually a check valve at the return side of the trans line at the trans inlet, sometimes the shops add another this will cause a fluid backup......... or restriction.
How many coolers are installed........ does it go into the rad first then the cooler.

FWIW, I would never use one of the worm-drive style band clamps on an oil hose - for either tranny OR engine oil. I've seen too many of them work loose.
For something as critical as an oil line I use the style with two wire hoops and the bridge piece with the bolt through it. I don't know the name for that style, but they have a LOT more grip.
In fact you can over-tighten one to the point that it cuts through the hose. Don't ask me how I know.....

I did the fluid change myself at the shop and i never pulled that hose off and the clamp was tight. I really should have replaced it. The hose goes from the tranny to the aftermarket oil cooler and back again(only one cooler). Its completely disconnected from the rad. In the morning i am going to take 2 or 3 of those screw hose clamps all at once and top her up with tranny fluid. Not much fluid left in it at all. Do you think that there would be any damage to the tranny?

Nah, unless you sat there for a while and kept revving it in gear without fluid, you aren't likely to have hurt it. I wouldn't think sitting there in neutral pumping the oil out onto the ground would be likely to do much damage.

no, you did not get it hot enough to hurt it. when you top it off, do so in small amounts (1/4 qt) at a time with in idleing in park. when you get it close, shift through all the gears just to get all the bubbles out. once you get it near the cold full mark, you should be safe to drive it. recheck it when hot on level ground.
be patient, you will get some funny reading from the fluid in the tube getting on the dip stick. if you happen to overfill it, you know witch cooler line to remove to let some out don't you !!!!!!

It really is recommended to run the cooler lines through the rad to help warm up the tranny. RUnning a tranny under operating temps is as bad as running them over on temp.. the tolerances were set up for running at normal operating temps. In the cold, it takes longer to get to temp. Might be ok in the summer months, but it is recommended to run through the rad...

I live in hawaii so, on the advice of a local mechanic, i also bypassed the radiator when I put an aux cooler in. You don't have to worry too much about warming it up when ambient temp rarely drops below 70. While the warm-up time may be a valid concern, make sure the radiator is really clean before reconnecting it to the tranny. If the cooler was installed after a rebuild the radiator is probably full of old clutch material that will just clog up your valve body on your fresh tranny.
