Refilling a torque converter....

[rusty ol ranger]

Its not on an RBV...its on my 99 Crown Vic. 4R70W trans.

Its has a drain plug on the converter...but how do you go about refilling it?

Im getting some slight shudder once in a while...hoping fluid/filter takes care of it. Fluid is old looking but dont smell burnt and trans seems fine otherwise

I usually roll the vehicle over after the converter has been drained. Then fill it through the drain plug hole.

Remove drain plug, pour in fluid, replace drain plug?

I don't know. I pulled the plug and drained the one that came out of my Explorer. I just assumed I would get a funnel and fill it as full as I can before I put everything back together.

Have you searched for YouTube videos?

Now I'm going to be lazy and let you figure it out first.

I didnt youtube no.

I googled it..and get conflicting info.

Some say fill the pan, start it, and keep adding...but others say dry firing the converter will eat it up.

I did a bunch of those back in the day. I always just let it idle until I had close to what I thought had come out combined ( pan and converter). Then start working it through the gear ranges.

Says it holds 14qt total.

So top off the pan, fire it up in park, let it run for a minute or two...add more?

Fire it up... and start pouring. Don't wait... pour.

Been awhile... I don't remember it being that much fluid.

Thats what im seeing online. 5 in the pan...maybe 14 total. So 9 in converter

Maybe ill see what a shop charges,i really dont wanna replace the converter

Maybe @19Walt93 has a better way or advice

It has been a while since I looked it up. But it's more than you expect. Don't forget you're filling external lines to the cooler(s) also.

Just fire it up and let it run while adding and checking the dipstick every now and then, you're WAY overthinking it . It literally has a pump for that and since you're supposed to check the fluid level while running just do that...

 

[scotts90ranger]

Fluid and a filter is a good start, could help... as long as the magnet in the pan doesn't look too bad you could have good luck, once they start gaining too many forward gears then you have problems... when I got my Explorer the 4R70W went forward in every gear but park... then did it again 20k later when the gear cluster thing blew up...

Not sure as far as filling it, I didn’t drain my torque converter on my 4R70w, at least not yet.

I would suggest doing the J-mod, that may help with the shudder too. All you need is a couple drill bits and a couple gaskets.

Jmod?
