Planning on changing the fluid on my transmission this weekend. I have heard that the type, most likely a 4R70W, is listed in the door sill... but I am having a tough time deciphering it.

A: Do I have a 4R70W?
B: I am going to drain the Torque Converter as well, any concerns?
C: How many qts am I going to need? I have heard 9... and its Mercon V

Any other suggestions would be greatly appreciated.

Regards,
Jeff

 

Year and model of your truck and engine size would be helpful..............

A.) Yes

C.) should be in your owners manual

have you already bought the fluid? i heard Royal Purple synthetic is a great buy for automatics

 

True... im an idiot.

99 4x4 XLT Supercab 4.6L

 

You have a 4R70W, and your torque converter has a drain plug. You will need 14 quarts of Mercon V ATF. If you want to change the fluid in the transfer case while you are at it, that's 2 quarts of the same fluid.

 

Transfer case takes the same fluid as Trans?? Show you how much I know---or DON'T know!!! I thought it'd be some special weight gear oil or something---DirtySCREW

 

some do some dont..

i didnt think the torque converter had a drain plug.. the converter alone holds like 3 quarts..

 

The converter holds a heck of a lot more than 3 quarts. A dry fill of a 4R70W is 14 quarts, but a pan drop only takes 5 quarts. Ford automatics had converter drain plugs up till sometime in 2001. All 97+ F-150 transfer cases take ATF.

 

Transfer cases used ATF earlier than 97.

My 91 F250 used ATF in the T-case.

 

I'm sure ATF transfer cases go back farther than that - I was saying it in the context of this exact forum - 97-03 F-150.

 

I have a 97 F150 4X4 4.2 litre Automatic Trans, How do I change the Filter and Fluid best advice

 

Drop the pan, replace the filter, drain the torque converter, fill with new fluid. Reuse the pan gasket.
