Ever heard of a 904? Supposedly it's just like a torqueflite, except it's made out of aluminum instead of cast iron like most torqueflites, and it's not as long, and is totally different than a torqueflite, and it has OD, where the torqueflite didn't.

There's a guy on another site I visit who can't understand that all rear-drive MOPAR autos were called torqueflites until the 500/518 came along, and doesn't have a clue. Some people never listen.

 

i have had numerous tranny guys tell me i have a 46rh not a 518 and some say they make both 518/46rh in lock up and non lock up versions

 

I did a search on flea-bay and found a couple different places with reman A518/46RH/47REs listed, too.

 

Maybe this explantion will help.

The 904 is to the A500 as the 727 is to the A518.

46RH and A518 is used interchangeably. There were no diesel lockup versions built, but most of the gas units were built with lockup converters.

 

A 904 is a smaller version of a 727. I have a lock up version in my 90 gasser but they are 3 speeds with no overdrive. They also have a lower first gear ratio than a 727. I have never seen a 727 with a cast iron case they are always cast aluminum at least the ones I have seen.

 

Isnt the 904 dodges small block gasser trans? I seem to remember my 360plymouth scamp had one.

 

Yes it is, I had a 1974 Dodge Dart with a 318 and a 904. Put one behind a Cummins - should be good for one run. Ha Ha

 

As is found here: http://en.wikipedia.org/wiki/TorqueFlite

 

That may be true for all the 3 speeds. The 2 speeds were called Powerflite. Air cooling on the 301 Chrysler, and water/oil on the 331's. The C300 version got extra clutch plates on the drive clutch. None ov them could stand living behind a 392...

I believe the truck transmissions were "Loadflites" in Chrysler propaganda.

 

LOL, ask the NHRA Super Stock guys and they will tell you they were factory behind their Hemis......... Lots of them run them to get the last 1/1000 of a second shaved.

 

A 904 never was made with a bigblock bell housing were they using an adapter plate?

 

That was always what I thought. I don't know for sure, because now all of them run JW Ultrabells for SFI certification, but this article on Hemi Darts was back in the early 80's, long before JW was making them. They said something about a Canadian version, but I fail to see why they would do something like that. Dunno, it could have been pure BS as well, sometimes rags like to put funny facts out, but if I remember correctly, that article was in SuperStock and Drag Illustrated, which had pretty good tech.

I remember it because I thought that was about the dumbest thing I had ever heard, given my experiences in killing 904's..

 

I think the 904 was available in a big block version, but only came behind 383s and 400s.

 

this old man has never seen a big block version of a 904 but i did see one in my shop several years ago with a chevy bolt pattern in a mail jeep. 10 years at a dealer ship 60s-70s and never saw one behind a 383-400 engine either
