well after hauling our 32 ft fiver to it's final resting spot in an newly developed seasonal site,and encountering all kinds of problems shoe horning it into position with a very tight corner and soft approach getting stuck in the process having to use 4x4 low range for the first time i noticed my trans temp. gauge reading 240 F!!! i almost had a heart attack.As soon as i got home i dumped the transmission fluid and replaced the filter,after which i did the cooling line transfusion which is so easy to do,but in my haste if left out the **** MAGNET from the pan.Would it still help to place it on the exterior of the pan it does seem strong enough and i might pick up a stronger one as well,talk about a DUH!! moment!!

 

The magnet on the outside will work just fine....

 

240 is not out of line when working it hard. Some of these trucks hit that daily.
