Transmission Cooler Line Popped Out

[j91z28d1]

If the new radiator is defective, not cooling the transmission fluid down could that cause this problem? The upper radiator hose can be squeezed all the way to the middle at running temp, the lower radiator hose looks huge. My transmission got up to 238° at idle quickly today. I do have some forward motion now in 1st-Drive, no reverse feels like it's in park and neutral makes a whining noise at transmission and acts like it's in drive with forward motion. I drove a mile and a half total when pulling in my driveway that's when I saw smoke from under the hood.

this doesn't sound right. yeah, if there's no water flow across the radiator from a blockage, or somehow how the internal transmission cooler is blocked, it might explain why it's getting hot so fast and you don't have any tranny line pressure to engage the clutch packs for the gears.

that said, I've never see it happen. but anything is possibly. I know coolent is expensive but might be worth checking into.

I think this is my next step. If I was to take it to a shop to find out what is for sure wrong, do I take it to a regular automotive repair shop or a transmission shop? I don't trust either. Especially being a woman.

I feel like either could do it if they are even a half way decent mechanic but throw the scammer up from behind the counter in the mix and who knows. I'm honestly not sure which would be better. maybe a tranny shop?

I don't trust walking into shops myself, I know I'm going to end up getting screwed too. I do feel like a woman walking into a shop is like jumping directly into the sharks open mouth just for sport lol.

yeah the tranny shop might be more used to checking line pressure at the transmission with a scanner and know what they should be seeing. Hopefully any tech can tell if water is flowing thru the radiator.


did you happen to replace the thermostat while changing the radiator? did you change it because it was leaking or over heating?

I will start by saying it's physically impossible for the transmission line to have just popped out on it's own IF it was previously inserted properly.
that being said it's likely if you drove it around with no fluid long enough you could have damaged the transmission bad enough that it's internally fried but really hard to say.
how far did you drive it after replacing the radiator? how many miles? if it was more than 5-10 miles you could have cooked it.
there is really no reason for it to get up to 207 just idling unless the fluid is still low or not flowing, blockage, etc.

really hard to just "Guess" without being there, my best suggestion if you want to try and avoid a shop is to pull that radiator out and exchange it for another one and see if anything changes

I changed it because it was leaking, spraying right on the PCM. No I did not change the thermostat. I knew I should have & kicking myself for not.

if it was just leaking the stat is probably fine. good to change but I wouldn't expect it to all of a sudden stick closed because you changed radiator. if it was over heating before hand, I thought maybe the stat was stuck closed.


only thing else besides pulling it out and swapping it, which would eliminate a lot of what ifs if you can. but if you have it out, you could run a water thru it from a hose and see if it flows out the other side.


sometimes things come with plastic caps on the fittings. is it possible one got missed and hose over it, or pushed inside?
