I didn't get the correct tube & dipstick with a 727 that came out of a 72 Dodge 1500. Another 727 tube/dipstick that a guy gave me does not mate up to the housing as there's no boss on the transmission for a bolt that goes through the tab on the tube. Anyone know what the correct dimensions are for the "Add 1 pint" and "Full" marks would be from the base (where the pan bolts on) of the transmission? I may end up having to make a tube and dipstick to get it close to the engine. thanks gatz
Yep to what he said, that is where the tab will bolt to but on 727 dipstick tubes you also have to contend with whether it was built for small or big block applications. http://chucker54.stores.yahoo.net/trststdi.html Worth looking into as their prices are pretty friendly.
The tube that you need does not use that bottom tab. It is secured to a engine to tranny bolt and simply gets shoved into the tranny with an o-ring. The stick has a pointy end which is 3/16 long. The pointy end extends below the bottom of the case (where the pan gasket is) 3/16. The full mark is 1 3/4 above the tip. The add 1 pint is 5/8 below full.
270, I'm chasing the same cat, somewhat. I have a 727 (big block) from TPI (no longer in business). It came without a dipstick assy. I've purchased 2 dipstick assys, (Mopar reproduction parts), one for a big block and one for a hemi. They both are the O-ring type (like you've shown) with a mounting tab high up on the tube. Yes, I know where it bolts to. My problem is that with those type, the o-ring is above the trans housing. My trans does have a bolt hole next to where the tube goes, like in your last picture. Are those type of tube available ? If you need pics for what I'm trying to say, let me know.
i think 65 or maybe 66 was the last year for the bolt down on the trans case 65 and 66 was a big transition period for mopars
Gotta watch what the tube and stick came from. Cars are different from pickups, and vans have a really long tube and stick.
Well, I took the pan off to see just what was going on. Whatever the tube a'y came from; it fits snugly into the case, and the tip of the dipstick is ~ 3/16" below the pan mounting surface. Did they just rely on that tapered fit to locate the tube vertically?...would seem a bit inaccurate. As previously mentioned, there's no threaded boss on the xmsn housing for the small lower tab on the tube. Also, the higher tab doesn't seem to line up with any of the xmsn-to-engine bolts either. The S/N of this transmission is PK349638 3771 5442 and was told via a HAMBer that it was from a 72 Dodge 1500 So, perhaps I should be looking for an assembly from that vintage of pickup - it may be longer than what I currently have, and might be easier to get it closer to the engine. Alternately, if I make one that will "hug" the back of the engine better, I could drill/tap a hole in the case for a tab that would locate the tube more positively. gatz
Gatz, good luck on finding the an original tube assy. Is there a way you could get a measurement for me, in my quest.....From the top of the housing (where the tube is inserted) to the bottom of the trans (where the pan attaches) ? Maybe 270dodge could do the same for me, seeing as how I used his pic Thanks in advance
gatz, in your third pic where the bracket is that bolt hole beside it is where it goes no-one says you cant bend /manipulate the tube to make it fit just dont bend it double
i dont want to be a dick but not just to the OP but how can people not see this kind of stuff i hear things like this every day
Hippy, it was a just a joke, No harm meant. Thanks for the infor on the insert / stop. Now here's my problem....... It's a Mopar Reproduction tube for 68-70 Big blocks with a 727 After doing my homework, I found out my trans was built June 30th, 1967
And here's another oddity. These are both Mopar Repro. 68-70 B-Body, One for Big block, one for Hemi, but both using a 727 trans. (Hemi on top, Big block on bottom) Yet, both dipsticks are marked the same..... My friggin' head hurts
270dodge ! Thanks for the info in the pdf. Here's what I found out.. 727 Transmission PK2081543L 2467 7196 PK = Plant Kokomo 2801543 = Chrysler / Dodge / Plymouth, 1967-68, 8-383, 2BC L = ? 2467 = Build Date, June 30, 1967 7196 = Sequence number built that day
did some reading if you run a stanerd converter it 8qt 103/4 converter 6.74 qt i think the repo dip stickes may have some problems i see no difference in hemi on standerd bbm hope someone may make more sence of this for us
Crystal Blue The distance between the pan gasket and the top of the boss(as indicated by the red lines) is 1 9/16 inches. The top of this boss is actually the full level.While were kicking the fill tubes around I've actually used tubes that were 5 inches long. No problems. I built TFs for drag cars back during the war.
Oh well big block and hemi trannys- there is no difference except for the internals. The case and fill tube are the same. Do not go to drilling holes for bolts, you'll be sorry! Use Ma Mopar's system. Just get that o-ring down into the case and secure the tube with a bracket to a tranny bolt. After that see the pictures to set the stick at the correct level.
chrystal blue in your pic of the two tubes it looks as if the bottom tube didnt get the finish process to roll the edge ive never seen a mopar tube like that one they've allways had the blunt end on them
How short can you go with the fill tube? Here's one that I built around 1968 for a T with a bunch of setback.I needed a short drive train. It worked well.
Crystal Blue, I measured the boss thickness where the tube a'y fits and got 1.24" which is quite different than the 1 9/16" that 270dodge got.
OK fellers, were chasing this rabbit with the wrong kind of dog. I've just drug out 6 different TF's and all 6 are different thicknesses. This casting could be 4 feet thick in that area and that would not affect the relationship of the machined surface to the valve body. The one true measuring surface is the bottom of the case(that 3/16 thing). Oh yea these things get heavier every year and if I gotta drag em out again someone owes me a case of miller.
