Overheating transmission?
#11
ATF to the radiator has its own line inside the radiator tank that receives the line and then goes to the radiator that's sits in front of ac radiator right behind the grill. I'm running a gauge on my trans and have only seen 197 once when I was stuck in traffic for like an hour and outside temp was in low 90s. On a regular drive consisting of stop and go I'm seeing about 166. If you're constantly in the 190 to 200 range and you're not in the desert something may be up.

Friday morning I was on my way home from work in my 2007 Lariat with 118,000 miles and got stuck in one of the worst traffic scenes of the year. I idled/went under 5 mph for about 2.5 hours in the Houston morning heat. Amongst all the other cars and concrete around, my external temperature gauge was reading 103*. I also have a Gryphon programmer and regularly have it on the "transmission only" program (program 1) which only firms up the shift points as far as I know. Normally my TFT (trans fluid temp) reads around 150* but that day it was approaching 270 when the message center in my truck beeped at me and gave me a warning about my transmission (I wish I could remember the verbiage but I can't). My AC also stopped blowing cold around that time. Both of these problems I attributed to idling for extended periods of time amongst all that heat but my question is why would this happen to my 2007 vehicle and none of the other thousdands of vehicles around me, including my wife's 2000? Is there something I should look at to make sure everything is functioning correctly?

As others have said;
-Change the transmission fluid, even if it's a series of pan-drops.
-Try to prevent extra shifts, and turn off the OD when in traffic.
Also;
-You could install a larger auxiliary xmsn cooler.
-You could install a larger transmission pan, with greater fluid capacity.
-You could install electric fans, but do your homework and do it right. (that's what the Ford engineers finally did).

I think you need to avoid 2.5 hour traffic jamb’s...

IF the engine and transmission are both getting hot, then my first move would be to flush all antifreeze, install a new thermostat and replace your upper and lower hoses. I would also drop the transmission pan and replace with a new filter and put a drain valve in the tranny pan so you can change out 4-5 quarts of transmission fluid several times over the next couple thousand miles.

If you want to change all the fluid, is there really a down side to disconnecting the line from your cooler and let it dump out while the engine is running. Obviously you need to be adding new stuff in through the dip stick tube. I've considered this because I'd like to flush out all the fluid vs doing pan drops which I've been doing. Seems like a good way to get it all flushed without having to pay a shop to do this.
