Post subject:  Trans Pics ID needed
Does anyone know what I have here. I beleive the trans is around 1969. Can the stall speed of this torque converter be determined from the pictures? What do you think of this front seal?

This isn't a '69 transmission, it's an early-production '66 unit from behind a 225, same as it was last summer when you asked before. :D :D

The stall speed is to some degree dependent on the characteristics of the engine, so no, a picture cannot tell you the stall speed. But, the stall speed on the stock converter in this transmission, behind a stock 225, is around 1600 to 1800 rpm.

Are you aware of the governor weight rattle noise and its correction for early '66 transmissions like this one you're working on?

I know that trans looked familar. :D :D
I not aware of the governor weight rattle noise and its correction for early '66 transmissions like this one I am working on.
Maybe I could avoid this trans altogether. ((2538337Y 2017190)early '66)
Could I install the valve body from the early '66 into the 1967(2801533Y 2539494) My 67 shifts very very hard. I ve been told I may not be able to "unenginer" the hard shifting without a valve body change.

I have very little time with the 66 trans. I test drove it for about 1 mile and it shifted smooth. The car had a bad muffler so I don't know about any possible ratttles with it. The 67 trans I drove 700 miles home and a couple thousand more around town. It only problem that I am aware of is it will chirp the tires with its 1-2 shift and 2-3 is hard also. Keep in mind that this is a stock super 6 225.
Do you think the valve body will swap over and fix the hard shifting. I don't want to spend much money here because I am looking to get a large input shaft trans to build later.

Dan-
I hoped you wouldn't remember that ID. I just wanted to keep a nice package here. Quite the memory.

thanks for the help.

Is that a problem? :) Where, and how did you get it to shift like that?! Wanna do some trading? I'd seriously like my slant to chirp the tires.
I know, I know.....it's harder on things, ect. But it gives me a big grin just thinking of a 225 doing that.
Darn my Hot-Rod soul! :twisted:

Well, my memory ain't all that great. It was just like "H'mmm...I'm sure I've ID'd this trans for him before", then I ran a search on here, and while that was running I went in the '68 FPC...nope, all the trans numbers were higher than 25xxxxx. Went to '66 and found your number immediately.

The governor rattle is not harmful, just annoying, and it is cheap and easy to fix. '66 was the first year for the major redesign of the Torqueflite (new rod-operated gear selection system, eliminated rear pump, eliminated reverse blocker valve, etc.) Up through '65, the governor received pressure from the rear pump. Zero pressure from the rear pump when the vehicle is standing still, 'cause the rear pump is driven off the output shaft. For '66, no rear pump, so the gov had to be fed from the front pump, which does supply pressure whenever the engine is running, including when the vehicle is standing still. Early-production '66s had no snap ring against which for the gov weight to rest, so under certain conditions with the vehicle in "D", "2", or "1" and standing still or moving very slowly, you can get a grumble/rumble/sort of an air-hammer noise coming from the trans. It's the gov weight oscillating rapidly. There's a TSB showing how to install the needed snap ring, and later-production transmissions have the snap ring. I had an early-production '66 trans in my '65 for the last 6 years I owned it, and it made the noise. Annoying, but not annoying enough to tear into an otherwise perfectly good trans.

Thanks interesting info about the rattle.

Are the valve bodies interchangable between the two? If so, whats the difficulty level here?

Post subject: 
Yes, the valve bodies from A904 transmissions (slant-6, V8, doesn't matter) are all interchangeable as direct swaps in the '66 through '77 year range. It's a simple remove/replace operation, but it might be wise to take a careful look at the valve body you intend to install to make sure it's not full of "mud". Also, you'll want to replace the seals that are disturbed in the R&R operation (gear selector shaft/kickdown shaft seal).

Don't forget to save yourself a lot of hassle and prevent a pan leak before it starts; stop by the Chrysler dealer and get the really nice double-seal, reusable rigid pan gasket P/N 4295875AC and use it instead of the floppy original-type gasket.

I have a BB 727 from '65 does it have the rattle? Not that I am running it in anything soon. Just thought I would ask.

No, the rattle was in early-production '66 units only.
