Tranny, Transfercase & Diff Fill Hole Thread Sizes

[Peepers]

Hey guys,
I'm looking for the hole sizes and thread pitches for a 2G AWD tranny, transfercase and rear diff. I'm looking into ordering some barb fittings that I screw in making attaching a rubber hose a whole lot easier to fill the units with fluid

Any info would be greatly appericated
Thanks

Until someone knows, my best guess is 3/8" NPT. I don't think they're BSP, like the oil sender is.

However, you're better-off to just use some vinyl tubing put loose in the hole so you can see it going in, and see when it starts to overflow (full). Pumps for the lubes are on the shelf next to the fluids.

If you're doing fluid changes, remember to always remove the FILL plug FIRST. You don't want to find out it's irremovably seized after you've drained the case.

CAPS says "16" for the transfer case and transmission fill plugs (which are the same part number). I believe this means 16mm threads, but I'm not totally sure, and I don't know the thread pitch. Unfortunately, it gives no information on the rear diff plug.
