Default Re: changing transmission fluid and filter on 2008 3500 nc3v

Is it possible to extract transmission fluid via the dipstick tube? I read there is a bend in the dipstick tube. I'd like to just change 3-4 quarts of fluid this way in between service intervals. I had it professionally changed at 40K and am now at 65K with slight RSN downshifting from 2-1 gear.

I did my service yesterday. 2008 2500. 125,000 miles.
I had to use the heat gun to get the plug off.... it was crazy tight.
I did the same, supported the tranny and removed the rear support cross member- then jacked at that location.
Preparation......
put cardboard down (oil we be everywhere)
Have tall jacks available and lots of wood cribbing before you start. All of the floor jack I have were too short. I used a camper screw jack stand (it takes very little force to support / hold up the transmission.
If it not a level surface you will have lots of oil in the pan when you put it out. (seam obvious, yes)
The transmission needs to jacked to get clearance room to remove the 2 front pan screws and to be able to pull the pan out.

Once the cross member is out its easy to get around under there and see what you have. (I had lots of dirt and gravel on top of the cross member - be prepared)

I dropped the pan and changed the filter. I did not attempt the torque converter... too much trouble to get to it and fight it - especially knowing how tight the pan plug was!
Pan only drained 3 quarts so that's what I put back it. I will run it for a few thousand miles and drain again and refill. I plan do this 2 times. My main goal was to get the pan dropped, change the filter and clean the inside.

the first time i changed the fluid i removed the cross member for easier access. it was not too difficult, but sprint guy (iirc) suggested just removing the bolts from the cross member to the transmission housing then using an appropriate size of wood stock, jack the transmission above the cross member. there is a round opening in the cross member to place the wood stock against the transmission housing. it was much easier and way faster. plenty of room to remove the pan.
the torque converter is sorta of a pia, but once you have the correct tool, not so much. a .25" drive socket with an extension with a jointed end makes quick work of getting to that small allen screw. sorry, i don't remember the size of the metric allen socket.

i went back to the original post and copied carls suggestion.
he states it better than i did.........i also noticed the size of the allen screw on the torque converter is 4mm

On the NCV3 3500's only (sorry Jon) , to remove the pan : simply remove the 2 bolts that go in from below the cross member on both sides of the mount , then place a jack and a piece of wood under the center of the mount (round bushing ) and finally jack carefully and the trans will raise off the cross member. I have never removed the cross member to service the NCV3. Lastly you can access the drain plug for the torque converter when the trans is raised (lifted) much easier that way.

Looks like extracting fluid from dipstick tube is very possible. Handy if you don't want to do anything but refresh fluid.

Any idea of the specified torque for these two bolts?

I actually found more than a note.

purchased the ultimate sprinter service manual, and it brought up a wealth of info.

for my 2015 MY 3500 with a motor home on top, (by the VIN lookup)

the following torque is specified. (my conversion to inch pounds)

transmission oil pan drain 22 nm (194 inch pounds)
Transmission oil pan to housing 9 nm (80 inch pounds) I know some folks say 8 nm, perhaps an earlier or different application.
torque converter drain 8 nm (71 inch pounds)

the two mounting bolts for the rear transmission support to the frame get 58 nm (43 ft lb)

At 38,800 miles, the fluid is quite dark.

https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
proved quite helpful (with a T25 bit) for the torque converter drain plug. Dennis had suggested finding a tool truck for a similar tool. I ordered a spare, which came in handy since the bit is stuck in the original plug.
The local MB dealer considers the plug a special order item. (what does this tell you?)

I pulled the bolts on the support to cross member, and used a couple old ones from my VW, then jacked up for clearance.

found that most of a mess can be avoided if you drop the pan, and prop it in place, then pull the filter inside the transmission down a bit let it hang at an angle. this lets most of the fluid above the filter drain out. then place the filter in the pan, rotate 90 degrees (yaw) and remove.

here is the transmission pan and original magnet all cleaned up.



and a photo of the torque converter drain plug



the tool mentioned in previous post makes this a fairly easy job. used a quarter inch hex drive torx bit.

looking at the photo, it looks like a straight sided hex (allen) socket, which may explain why the torx bit bonded to the drain plug on removal.







These are not the drain plug.
