727 vs A-833 Weight

[inri]

Just wanted to put it out there that this weekend I weighed the following:

1969 727 Transmission w/stock transmission pan (no converter, no transmission fluid, etc.) - 126 lbs

1967 A-833 Transmission 18 Spline (no bellhousing, no clutch, no linkage, no rods, etc.) - 113 lbs


I imagine that once the following ancillary items are taken into consideration for each type of transmission, that they would more or less weight the same?:

727 - Torque converter ( 15 lbs) + 9 quarts of transmission fluid ( 16 lbs ) + transmission lines (1 lb ) + transmission cooler (1 lb) = +/- 33 lbs

A-833 - Bellhousing ( 25 lbs?? - this is a guess) + clutch ( 10 lbs - this is a guess also) + 4-speed linkage ( 5 lbs - also a guess) = +/- 40 lbs

Total weight 727 = 126 + 33 = 159 lbs

Total weight A-833 = 113 + 40 = 153 lbs

I was under the impression that manual transmissions were 50 or more pounds lighter than their counter parts? Was that an old wives tale or what? If anyone has better numbers for the A-833 Bellhousing, clutch, and linkage please let me know. The above is just some food for thought.

Every torque converter I ever picked up was way more than 15 lbs and you forgot the flywheel. Your probably a little light on the pressure plate but I have a disc and pressure plate I can weigh

I'm going to weight my converter with flywheel today and post my findings. Let me know regarding the disc and pressure plate. Thanks.

All I can say is this, I cussed more installing my A833 than I have installing a 727 by myself. However, I look forward to jam the gears once I get her back on the road.

Disc and pressure plate 23 lbs

I've never done a girlymatic in a car, but I did a couple 727s in my Power Wagon's. Even with the transfercase, it was easier than a 833. Might be that the truck sat a lot higher and was more worker friendly.

Maybe if you were comparing the later aluminum case 4 speed with an aluminum bellhousing, the weight might be a bit lighter than a 727... Even then, it wouldn't be 50 lbs.

Ive put in a couple 833 i replaced the clutch in a 84 dodge pickup with a 833 over drive that one felt a lot heavier than a regular one. had to get a friend to help me i used to put 727s in on my chest that was a long time ago though ,

Put a few transmissions in like that myself, always found the automatics more cumbersome, bigger, bulkier, harder to see what you are doing. Weight probably wasn't much different.

I could put the 4 speeds up on my chest, but I couldn't balance the 727 well enough to try it.

Wouldn't even think about it doing it without a trans jack now.....

I've heard for years about guys puttng 4 gears on their chest, never tried it myself.

Just did one but I think they are getting heavier I lift and balance the tail shaft with my knees and I use guide bolts in the two lower holes with the heads cut off. The hard part is getting under the tranny

It's my opinion that cast iron gets heavier as it ages. It must absorb moisture from the air or something.

All I know is all that car stuff used to be a lot lighter 20 years ago.

Back then i used to drivw a residential garbage truck id probaly pick up 800 houses a day me and a helper i would probaly jump out of the truck 4 to 500 times a day so . i was in pretty good shape back then but now im paying for it i have a trans jack now,

A bit late, but for those that stumble on this thread in the distant future will nonetheless appreciate the follow up post

A 10" race converter weights 22 lbs (on average), which is 7 lbs heavier than my original guesstimate.

Same here, when I installed my 833 last fall, I was using my old floor jack. Well being and old jack, it lost pressure while the trans was being installed. When it lower the trans became off balanced and fell off the cup and on to the floor and my hand. Thought for sure I had broke something including my hand. Fortunately I did not have the car to far in the air. Eventually I did get it installed using a trans jack.

Oh and Inri, there is no such thing as being late to posted thread, that the reason for the site to share our experiences and give advice.

Thread over at Moparts says 18 spline with oil minus the levers was 120 lbs

Flywheel approx 35 lbs
Clutch and steel bell housing 65 lbs (alum bell housing way lighter but ??)

So total 220 lbs


Does someone have an actual weight of a 727 w/TC and fully filled?
