I agree with goodguy , but I won't argue with wetry either. BUT ......a thought did occur to me ( and I got a headache shortly after) is A/T line pressure below 15PSI , if the cooler is bad then it should be transferring A/T fluid to rad. when line pressure exceeds pressure in cooling system, right? OK , I'm going to take some ADVIL.
DRVING IN DEEP WATER, OR MORE LIKELY DEFECTIVE TRANS. COOLER INSIDE RADIATOR. MECHANIC CAN CHECK THIS WITH LOW AIR PRESSURE. TRANS. NEEDS TO BE FLUSHED BEFOR DRIVING AS GLYCOL WILL DAMAGE CLUTCHES! ANY TRANS. FLUID IN COOLANT? ANY WORK PERFORMED ON CAR LATELY?
Thanks for all the reply's. A month ago I had a shop to replace the engine that my kid allow to run out of oil. Everything was great with the replacement engine but the A/C quit working last week (It was changed out during the engine change). The power steering return hose was leaking fluid, and exhaust flex pipe had a leak(which I noticed right after the engine change.) So last week I took it back to the shop. Picked it up Sat after a day in the shop. They fixed all those problems. I checked it out and everything looked great except that it shifted a little hard a couple of times when I was checking it out but I failed to check the Trans fluid because I checked it after the engine change and assumed it was OK.(my mistake). After a couple of days of driving my daughter said she smelt a funny or odd order. I checked it out and this is where I'm at. I also suspect a bad seal is in this mix also. I see evidence of it. Thanks again.
