My company remanufactures the 5R55S transmission. There is no need to check the fluid unless you have a leak. This transmission is different in many ways from past designs. Our techs use a special machine to fill the transmissions prior to shipment. They are installed at factory and at dealerships already filled and ready to go. This is new for Ford but not new to the industry. VW has been doing it for years.
Can you tell us about how the 5R55S is different? I'd sure like to know. And are the seals really that much better than before or is the intention to replace as soon as a leak begins? Thanks.
Raven i work for my grandfathers company and we rebuild alot of the gm and volvo units. I have heard that the auto unit will nto be able to withstand much power is this true? if so what can us auto owners do to beef it up?

So I guess since my 05 mustang 4.0, 51,000 miles, auto trans is slipping, I'm screwed. Every GM that I had just needed fluid checked and never did anything else with them. 1) Chevy 179000 miles. 2)Chevy 119000 miles. 3) Chevy 109000 miles. All were traded in and in good running condition. Good job FORD Guess that I'll wait until the end of the month and see what my GM dealer is up to. Needs tires and transmission fluid, time to trade it in! Just a side note, my current GM has 51,500 and has no problems.
so nobody answered the guy that said the autos cant handle much power.as a owner of a 06 gt i would like to hear more about this and also nobody answered the question does these trannys have a filter in them.i was wanting to change my tranny and all my fluids to amsoil synthic would this be a good idea.will it still be the same as that i will not need to check the fluid or do nothing to it for a nother 30k or is the fluid in it the only fluid that works that way with this tranny i am woried and wanting to do all i can to protect this car that i run hard and have never had much luck with ford trannys motors yes ford tranny no not in fords.transmission places love ford.so my question is will changing to better fluids amsoil the best there is help my car parts last longer since it is ran hard.
The 5R55S can handle about 550bhp (475 RWHP) There are several Super charger guys running at the track each week for years with no issues, Do a search for a guy called "Rygen" Turbo V6 rinning high 10's in the 1/4 on a stock 5R55S for two years.

its probably just low on fluid. you should take it in and get it flushed. that way they can replace 12 qts of fluid, vs, 5 qts if you drop the pan. they do have a filter, but its not really filter media, just a screen. you wont need to replace the filter. they recomend the filter at 100,00+. checking the fluid was described earlier in the post and yes, it is messy to check. with the motor runing at operating temp, you pull that bottom plug, if it doesnt spew out, its low on fluid. you can pump fluid up into it till it does spew, then its full.
