How much pressure is in the transmission cooler hoses leading to the radiator

i'm not sure about your car, but a lot of cars can have anywhere in the
range of 50-150 psi going through those lines. standard trans hoses and
properly fastened clamps will be okay.

Likewise, I'm not sure about the particular car being discussed, but
when vibration against one of the clips holding it to the frame ate a
pinhole in the metal line of an 80's vintage Ford F-150, and started
spewing tranny-juice all over bottom of the driver's side exhaust
manifold one evening far from home (I thought the freakin' engine had
caught fire, the smoke was so heavy!) I found that 3-4 wraps of typical
black electrical tape was an adequate "until the parts places open in
the morning and I can get a new piece of line" repair. Ended up not
having any option but to drive it for almost 4 days before being able to
actually crawl under and fix it proper, and when I did, found that
leakage after applying the tape was close enough to zero, and the tape
showed no inclination to "blow out". So for that case, the answer is
"comparatively low". Mileage is all but certain to vary from one setup
to the next, though - I have no doubts that there are vehicles out there
running high pressure to the cooler, and that such rides would have
popped the tape almost instantly.

I've been using rubber fuel line and hose clamps for years so there
can't be much pressure. Cooler kits often come with similar hoses and
clamps.

pressure is usually around 5-10 psi, very low. For the Camry, that is,
although it is similar for most newer auto. tran's. If U have the hoses
and clamps on right and tight, no worries.

I have never measured it directly, but I believe the cooler circuit
runs about 10 to 30 psi. You should be OK if the clamp is past the
tubing flare, but I can't help but wonder how you had any difficulty
replacing the hoses. The factory hoses go back on quite easily, and
new hose (of the correct ID) fits easily as well.

That said, the cooler circuit can move fluid at a high rate of volume.
If the hose pops off it won't take long to drain the sump.

they were generic hoses for tranny coolers,,, they were snug and I just
didn't get them inserted as far over the flare as I would have liked,
but they are on far enough that the clamp is fully past the flare so I
should be ok, just my usual bit of paranioa after a big job...
wondering about what I may have done wrong...

thanks

Always rub some fluid on the inside of the hose before pushing it on
the fitting and you will find it goes on easier and further. Do not use
KY jelly.
