How often should this be done? What type of fluid shoul i use?

 

as for the second part, i would use transmission fluid, but thats me. just messin with ya. definatly use a whole bunch of lock tite. it does wonders

 

yeah, your right. good answer punk lol

 

if you have an automatic, flush and fill it and change the filter every 25k-35k miles, use a high quality fluid, or a synthetic one

 

If it's an automatic, use Mercon V fluid. If it's a stick shift, just Mercon fluid. Change every 25-30k like Bob said. Take it to Ford and get it flushed if you don't want to do it your self. It's about $100 @ Ford. If you use a high quality synthetic like Amsoil, use their ATF fluid...works for both stick shift and auto.

 

ok I have an auto matic. it hasnt been changed in im gonna say 100,000 miles

 

is there a noticeable difference when you change it??? I havent done mine since I bought it 2 years ago well actually never done it before at all :(

 

Smoother shifting, cooler running tranny.

With that many miles, I would take it to Ford and have them flush it. They run a cleaning solution through it first to break down any build up and then run the new fluid through it so it should be good to go.

I wouldn't change it my self if it had that many miles. Check your tranny dip stick and see what color/smell your tranny fluid has. It should be red. If it isn't red and smells like burnt varnish, then it's bad and I would get it changed ASAP.

 

Uh yea, it is time. It is supposed to be red. It will probably come out brown.

 

it may already be too late, those transmissions like to give out if flushed after 75k or more intervals. talk to ford and to a good transmission shop first, they may suggest to just leave it be until the tranny blows

 

damn it! I dont want to get another tranny. But when you mess with crap with this many miles on it what can you do? ****.................

 

i have 73 k should i change mine?

 

i would say your in the same boat as me

 

Check your fluid. If it is red then you can have it flushed out. If it isn't red and stinks to high heaven, then take it into Ford and see what they recommend.

 

...So what did Ford recommend? I'm also in that boat.

 

My dads f-250 the only fluid he's changed is engine oil every 5k. Its an 89 and runs like a champ.

/the miles only are about 70k though.

 

well as of now I've got 139,000...I think the guy before me changed the tranny fluid so I'm iight, I Think its about time for new fliud

 

I have the scheduled maintainance guide right next to me that Ford sent in the
mail and it states 150K for transmission fluid change.

EDIT: Mines a 2003 though. I just noticed yours isn't.

 

I had mine changed from my Ford dealer at I believe 46k last fall. They recommended 40k miles, cost me 100$ from what I remember. The auto tranny did shift a little smoother.

 

Damn man, you guys need to be up on your preventative maintenance. I changed mine @ 23k. I'm at 26k now.

 

i did a full flush at around 30k...and switched over to amsoil atf at that time.

i don't think you need to do a FULL flush/fill every time.

when 50k comes around, i'll probably do a normal filter change/fill on it, which i think replaces about 1/3 of the tranny fluid.

 

its easier just to drive stick

 

Yeah til you gotta do the "slave cylinder mod" haha

 

Its super easy to change it on your own BTW....Get two 5 gal. pails and disconect in and out lines from the t-cooler(if you have one). Then fill one of the 5 gal. pails with fresh atf and plop the line in for the tranny in that bucket and plop the line out into the empty bucket. Start your rig place in N and just let it run. Stop the truck when you see bright red fluid comming out of the line out. Connect all of your lines back up to the t-cooler and top of the tranny... less mess and alot faster than the old skool way.

 

nows a perfect time to add a drain plug as well. makes changing the fluid quick and easy like an oil change. just make sure to install it right so it wont leak.

i have mixed feelings on the whole trans flush deal. all i can say is, change it 20-25K and ur way over due. others have the idea with the fluid smell and color.

the sad thing is, most ATF filters in the pan are more of a screen than a filter. they filter poorly and arent needed except for the suction neck. if u REALLY wanna get **** about an auto trans...do the following:
-temp guage
-drain plug or hi capacity pan with drain plug
-shift kit
-remote filter (like a remote oil filter)
-additional or external cooler
