That's not normal. Call a transmission shop and get their input.

First thing you need to do is make sure your full of fluid. They do lose fluid and without a dipstick you cannot tell if its low.
I drag race my car every month and it stays below 180 even hot lapping it. That cooler is cheap so for $89 it might be a decent mod.

808 you mean coolant?

Our transmissions are sealed, if he's losing fluid, he's def got a problem.

No I mean trans oil. While they are sealed you can and do lose fluid. When the trans oil gets hot it will vent into the bell housing. My car did this so I installed a trans catch can to collect the fluid. Its a must have if you have a blower and or race your car.

I learn something new all the time. I don't track my car, yet. Plan to get involved with a local autoX club. Is this only an issue with the 5R55?

So those times my tranny was extra hot it could have been venting into the bell housing and then leaking onto the road and I would have never known? When this happened to you did you notice the center console extra warm and were some downshifts clunky?

Also do you know of there is a stock trans cooler?

From Mishimoto website on performance radiator:

This item is for Manual Transmission vehicles. For automatic applications, please purchase optional Mishimoto transmission cooler (P/N: MMTC-U)

leads me to believe the autos come with a trans cooler built in.

That is correct you could have been venting fluid and yes we have a stock trans cooler. First thing you should do is check your fluid level. There is a DIY on how to check it. You do need an adapter to be able to do this. Not having a dipstick is quite the double edge screw job. Checking the fluid the ford way is a PITA and easy to get wrong. Installing an aftermarket pan and dipstick makes checking and adding fluid a simple job. Performance Automatic makes a deep pan and a stock pan with dipsticks. Because I race so much it was a must have item.

Alright thanks for that info. I'll find the DIY and go from there.

808 you seem to push that 5r55 hard. No issues with it?

Auto's come with a trans cooler built in. I know because I ordered a trans cooler when I was replacing my wounded stock transmission. When my mechanic went under the car to install it, he came across the stock cooler, wedged between the radiator, and A/C condenser. Funny thing is, it's actually bigger than the mishimoto unit. I just let him keep the mishimoto cooler for himself for any future project he came across.

I honestly didn't know the thing existed. Kind of deceptive marketing by americanmuscle putting that trans cooler in the 05-09 mustang catalog...
