I have plowed quite a bit this year and since i have plowed so much i wanna get my trans fluid changed, how much will the dealer charge to get it changed, also any other fluids that may have to be changed from prolong periods of plowing?

 

Trans flush/fill service is ~$130 in my area.

Maybe change the transfer case too since it's Mercon also?

 

Anyone know if Ford rates the tranny fluid up to 100,000??

 

i'd say to look in your book and follow that....should give you an amount of miles when the tranny is supposed to be flushed and re-filled...

they actually have a pump at the garage and they hook that to your truck then just pump the old out and put the new in.....it's pretty quick and usually around 100 to 130 bucks...

 

The 5.4 tranny fluid is considered lifetime, not sure if I believe that. Not sure what the 4.6 calls for. Flush is $132 in my neck of the woods, but a flush does not replace the filter, it does get the fluid out of the torque convertor. So maybe a flush the first time around and a filter change on the next one will surfice.

 

Lifetime, really? Yikes. The only application I'd trust any ATF for lifetime would be sitting on a shelf in a hermetically sealed glass jar.

 

ha-ha-ha, yeah thats about it.....

my suggestion would be to as a mechanic of find one on here that will give you a strait answer...

 

Don't believe me go read the manual it's lifetime on the 5.4 transmission. That's where I got it from. Doesn't anyone read the book!

I wouldn't trust a mechanic either. Lots of them still state to change your engine oil every 3,000miles.

ENHANCED AUTOMATIC TRANSMISSIONS

Matched to the new 5.4-liter V-8 is a new 4R75E automatic transmission, an evolution of the 4R70E used on the current F-150. Upgraded to handle the torque of the 5.4-liter engine, this transmission shares patented upgrades with the 4R70E, which backs the 4.6-liter V-8:

• A redesigned torque converter improves launch performance and increases efficiency.
• A turbine speed sensor improves transmission control, providing the basis for fully electronic shift scheduling to limit "hunting" and to fine-tune shift speed and feel.
• Increased microprocessor speed improves responsiveness and precision of the control system.
• "Smart" fully electronic shift scheduling knows what the torque will be in the next gear so it chooses the shift points based on the vehicle's projected performance in the next gear.
• Coupled with the electronic throttle strategy, the transmission computes the output torque required to maintain the vehicle speed, and chooses the correct gear and converter state accordingly.
• A sealed case and lifetime transmission fluid make the transmission maintenance free, while adaptive pressure control maintains consistent shift feel over time.

By predicting the performance of the truck in the next gear, the computer-controlled transmissions provide a more sophisticated solution to heavy demands than a simple shift delay switch, such as the one-size-fits-all "towing mode" some competitors use.

 

cool....i'd still ask a mechanic...(that you know) what he thinks....

 

How about pulling out the dip stick and actually checking the fluid? If it smells burnt or looks discolored then change it. If not, leave it be.

 

thats a good idea also....hopefully it doesn't smell burnt....

 

I don't know how ford could call this a selaed case when it has a dip stick not very sealed IMO, most ford techs will recommend every 30K or so if you are doing any towing.

 

Do your self a favor and change it every 20 thousand, I always do and it works for me, they only do the flush now , depending on where you live it should be below 150 bucks for the flush, If Im rite the book says at 20 thousand it should be changed to keep up with the warranty ! but what do I know ? Check your book..

 

The reason Ford can claim lifetime fluid is the spec on the transmission fluid now is much better then in the past, It's a part synthetic and has much better additive package for longevity.

I would say every 20K is a little excessive in today's world! The owners manual makes no 20K claim on the 5.4 trans.

 

Where did you get the info from? Your service manual recommends changing it every 30,000!
