70 Challenger 440 Auto Dip stick find

[Marksmopar1]

  I thought I would toss this out to the masses

  I am rebuilding my trans for my 70 Challenger 440 R/T Automatic
I discovered this P# on the dipstick tube, the tube was unpainted.

   I have no idea if this is as original or what, just figured I would put it out there for those in the know.
For me it matters very little, but it may be useful to those building a top show car?

Cool....likely a replacement at one time, assembly line parts didn't tend to have part numbers printed or stamped on them

I just finished the rebuild on my 727 last weekend, all new seals/rebuild kit by TransGo.  My only concern when going back together was the dipstick tube wasn't even close to snug going into the case hole.  It felt like the o-ring sealed, but I'd have felt lots better had the tube been at least snug in the port.  This is the original, numbers matching transmission.  Being my 9th ebody, I've grown to hate Torqueflights for their screen door capability in holding back type F.  Last thing I want is another leaker.  Did yours seem a bit loose too?

The tube fit ok in the trans hole.... no leakage was seen...
  The fit really was not that tight at all, but maybe this tube being a possible replacement had a nice fresh O ring?
I know from experience on other similar type fitting that if the tube is even the slightest out of round it will leak.
Maybe best just to install a new tube, O ring and use some glycerin on the O ring when assemble for lube?
    A problem are on these for sure

If you want to stop the leak but keep a stock appearance what I've done on a few trans dip sticks was to buy one of the new tubes that use the GM style seal, cut the bottom 3" or so off, cut a like amount off the original dipstick tube & tig the new end on the old tube...

389 is a later part # I would say. I purchased a few dip stick tubes from the dealer and they did not have a part # stenciled on them, They had a part # written on a tag wired to the bolt hole in the tube. Not saying it didn't happen, I'm just saying what I have witnessed.

Looks to me like someone with a steady hand wrote the part number with a paint pen...

  LOL..
  Well, knowing where this car came from,,,,I highly doubt the previous owner hand wrote anything,,,nor would he have cared, trust me he didnt....
Although I can see how you would think that someone hand wrote on the tube.... But, it is possible a dealer stock employee wrote it on instead of the usual tag with a wire identification method.
   Either way, I shared only because I thought it was interesting, I will not be caring about the number, it will get a nice splash of paint
