I'm wrapping up compiling a database of Powerflite and A466 transmission ID numbers and notes and have a few numbers I found in manuals but without notes on the model of transmission and one without engines. I don't know if they are PowerFlite, A466, aluminum A904 (6-cylinder for 1960 - 1961) or standards. I place my specific questions at the end of each entry. Does anyone have documentation that answers the questions? Both digging through manuals and internet searches don't turn up anything.

2124725: 1960, 6 cylinder, Dodge, Plymouth after Serial P22118 (What transmission model? It could be an aluminum TF A904)

2125075: 1960, 6-cylinder, Dodge Dart, Plymouth (What transmission model? It could be an aluminum TF A904)

2229614: Late-1961 Truck, A466 LoadFlite (Did this transmission come behind both V8 and 6 or just V8)?

Thanks for any help.

Thanks Dave, and I too lean strongly toward the A904. The 1960's parts manual you show is where I found the two numbers, but I cannot find them in multiple aluminum TorqueFlite manuals I have. The fact that, according to the parts manual, they apply only to Dodge and Plymouth with a 6 cylinder makes the case for an A904 since the A904 was offered only in the 1960 - 1961 Dodge Dart and Plymouth Valiant with Slant 6. Full-size Dodge and Plymouth didn't use the Slant 6 to my knowledge and continued using either the PowerFlite or A466 behind V8s. The remaining variable is that 1960 Dodge trucks offered the old L-head 6 backed with at least the PowerFlite and possibly the A466, but the 1961 Dodge truck used the Slant 6. Deduction says if the two transmissions under discussion fit a Plymouth with a 6 cylinder, said 6 cylinder is the Slant 6 which makes the transmissions the A904. It would be nice to see that spelled out somewhere, so maybe I should be content now that I spelled it out

As for the 2229614 LoadFlite, I've reached a similar conclusion in that, to my knowledge, the only 6-cylinder offered in any Chrysler Corporation car or truck in 1961 was the Slant 6 family. Any automatic transmission, therefore, would be the A904, so the A466 at question would have gone behind only V8s that year. All the photos I've found of a 1961 truck with a V8 and automatic also have a three-speed shifter.

I suppose my questions are rather moot since I'm already convinced, but I figured someone here might have a manual with the numbers and more details.
