how often should i change my tranny fluid? how ofted do you guys do it

 

40k and never touched it...

 

I'm at 64K and I wanna do it. Just gotta find the proper tools to do a complete fluid change.

 

im at 85 and never did it.. but to answer the question.. i have no idea, lol. if someone on here gives a proper mileage as to when it should be changed, then i'll have something to do next weekend, lol.

 

And what should I refil it with? Any gear lube?

 

Owner's manual will tell you, and I believe that it's recommended for around 50-60k miles, but not sure about that.

 

just about every time i sink my truck.

 

The Ford manual states 30,000 and 90,000 miles for trans flush and assuming change of fluids cuz I don't think you can do it with out. I would suggest amsoil syn for fluid. For my truck it will cost 85.45 thats with a 4.0 you need 10.3 qts and you should do your transfer case (providing you have one) becaus it is the same fluid, its an additional 1.25 qts which adds 16.40 to the price. Hope this helps.

 

First question - what kind of transmission do you have?

Do not use gear oil. For many years now, all Rangers, automatic or manual, have used ATF although they use two diifferent types of ATF in newer Rangers.

Your owners manual gives fluid specs and capacities. It also came bundled with a Scheduled Maintenance Guide that gives change intervals that vary depending on how you use your truck - see the section titled "Special Operating Conditions". If you don't have these books, you can usually find them on eBay or look it up online.

General 2001 Ranger recommended change intervals:

Auto trans (Normal street use): 150,000 miles
Auto trans (Special Operating Conditions): 30,000 miles
Mercon V

Manual trans: 60,000 miles
Mercon

(Mercon and Mercon V are not interchangeable and should never be mixed.)



How about adding a short signature that tells us a few key things about your truck? Year, model, engine, trans, drive, etc.

 

ive changed mine every 25k

 

Change it every 30,000 miles, and use Mercon V

 

For Curiositie's sake, whats the difference between Mercon and Mercon V, and why aren't they interchangable? And why do all the Ford dealerships only have ONE ATF pump, and whats in it?
