If It Does Is It As Simple As Lining It Up With The Access Hole And Draining it out? As far as adding the fluid back in does anyone know how that goes. Is it as simple as pouring new fluid back down the dipstick and the tranny pump will pump it back into the torque converter.

Thanks

It should, and yes--fluid goes in the dipstick tube. Make sure you fill it with the engine running, and when it looks full, get in the truck and work it through all the gears with your foot on the brake, then recheck the level and repeat as necessary.

You are changing the fluid in the pan and the filter also,right? not much use draining and refilling the converter if you aren't changing the rest of the fluid in the transmission.

 

Well I wouldn't say "not much use". The converter holds a lot more fluid than the pan does so you are still getting about 6-8 qts. new fluid if you do the converter only.

On the comment about filling while running, I think we need to clarify. If you drain the pan and the converter, you are looking at about 10-12 qts. to fill it up. Put in about 6-8 before you start it, then finish it off. You do check the fluid on any automatic trans with the engine running, but you should not start it up dry.

 

Does My 1995 F150 4R70W Have A Torque Converter Drain Plug?

It may have a Drain Plug if you have an old Torque Converter as it had one when it came out in 1995.

But if it is like my 1995 with a replacement 4R70W Transmission and a newer Torque Converter made after April 2002 then it will not have a Drain Plug.

 

Thanks For The Input Guys. I Definately Changed The Pan Fluid & Filter (Added A Drainplug For Ease). I just changed the 1-2 Shift Accumulator Springs & Piston. Just Want Everything New As Far As Fluid Goes. I Think I Have Also Heard That You Should Add The Fluid When Its Off. Any Timeline that I should let it run after putting in the first 6 qts before I start adding more to fill the torque converter? Just dont wanna burn anything up.
Thanks!

You can add the rest as soon as you start it up. Look in your owner's manual and see what the capacity of your trans is, if you drain the pan and the converter, it's going to take maybe 2 qts less than total capacity.

 

I can't seem to line-up the drain plug in my torque converter (to drain) and now I'm thinking it doesn't have one either because the tranny was previously swapped and the converter is bright blue color - so it looks like it's not too old and may have been replaced.

Question:
Draining the pan and then breaking the line at the external cooler with one bucket feeding fresh fluid in (and pouring into dipstick tube) and one dumping the old fluid out of the tranny until it runs clean & fresh - Would that be just as good as draining the TC?
