Hello, 2004 F150, 4X4 4.6, 39,000. I changed trans fliud and filter. Now when I check the fluid cold it checks high on the dipstcik. When I warm it up, drive 10-20 miles, it checks add on the dipstick. Any ideas?
Thanks

 

i'd add till its good when its warm. Your supposed to check it when its warm not cold.

 

Ignore the cold reading. It doesn't mean anything.

 

Check it when WARM and RUNNING.

 

My 07 fluid dipstick says COLD next to the hash markings and pin hole on the stick itself. I presume mine is meant to be checked cold?

Im wondering because i did a fluid exchange yesterday.

 

The dipstick will also have a HOT marking. Ignore the COLD mark, that was somebody's stupid idea. Checking the fluid cold won't get you the right level.

 

Thanks for all the info.

 

I dont recall seeing anywhere it said hot. Only cold next to the hash markings and hole. I will double check incase i somehow missed it.

 

X2, the manual says to drive 20 miles to warm up the fluid.
