well im slowly getting my V10 EX back up to speed. i have only had it 2 months and i bought it with 144k miles.

next on my list is the transmission. dealer suggested NOT to flush it due to the miles and age. didnt want to blow any seals in it. they recommeded what they call a full service. it includes pulling the pan and changing the filter and refilling. they want $180 for this.

now in my past days, i have done this to my older S10 blazers and if i remember right, only like 5qts come out of the pan. so if this is still true, then i but there is only like $50 in parts in this type of service. is this true? can i really save that much and do it myself? i dont mind and have the time and know how. this is my first big 3/4ton and didnt know if they were that different.

thanks in advance!!!

 

I think the EX takes a whole lot more than 5 qts of tranny fluid. Check the manual for capacity. Isn't a filter and fluid change almost the same as a flush except not all the fluid would be exchanged (leftovers in torque converter)?

 

Way too expensive.

A proper fluid change won't harm your seals.

Here's Mark Kovalsky's step-by-step procedure for changing your trans fluid.

if you take it to aamco they will do the pan drop and filter change then hook the machine up to it and replace all the fluid in the tc as well for like 165 bones......

 

Well I don't trust our local aamco from past vehicles they worked on for me. I guess I'm gonna do it myself. My manual says I have a tc drain plug so I will look first. Now how much fluid will I need if I remove pan and drain tc? Also what and where to buy ATF? Dealer wants $4.75/qt of motorcraft mercon.

 

Ummm, did you miss my response to you? Did you see the link I posted for you in post number three above?

All your answers are found there bro, from the type of fluid to use, to exact step-by-step instructions on how to change the trans fluid.

You can keep asking questions in this thread, or you can click on the link have have all your questions answered. That link has all the answers you need!

ok i reread that article and the only thing it doesnt answer is where to buy. i remember reading somewhere on here that a guy found mercon for $1.95/qt but i cant find it now.

 

You want Merc V, not Merc, and it'll cost you a lot more than $1.95.

Any auto parts store will carry it. Napa, Karagens, Autozone, etc.

My owners manual, and my Haynes manual both say to use MERCON and not MERCON V ATF. But my local auto parts store recommend MERCON V.

Who is right and who is wrong. I am about to change the filter in the (4R100) transmission on my V10 and don't know what is already in there. I know you shouldn't mix ATFs so do I use what Ford recommend or what both you guys and the auto parts store say?

 

Ford discontinued licensing the production of MERCON in 2006. You can still find fluids that say they are for use in transmissions that require MERCON. What is in the fluid? Nobody knows since it isn't licensed.

The spec for MERCON V changed at that time to make it work with the transmissions that used to use MERCON. MERCON V is now the right fluid to use.

 

Ford changed the recommended ATF for the 4R100 after your truck was built and manual was printed. MERCON is no longer certified by Ford, all applications that called for it are now to use MERCON V (except the transfer case which now calls for XL-12). Any ATF labeled as being certified as meeting MERCON V specs is what you want. Following the full flush linked to above will give you the best fluid change at the cost of a few more quarts of MERCON V.

 

Merc V synthetic ran me nearly $200 to fill the 4R100 plus an empty converter. That's fluid cost alone through O'Reilly's since another FTE member and myself built my trans ourselves.
