[Amc-list] "Volcano" crank end for 61 and earlier auto trannys

[Frank Swygert <farna@xxxxxxx>]

I think that settles it then -- the 61 and earlier auto trans uses a special crank, 62 and later do not. Someone else had told me long ago that 61 and earlier used a special crank, but I couldn't recall who or if 61 was the actual cut-off date. I've only seen the Hydramatic crank, no 57-61 BW auto engines. All mine have been 63 and later, but you can tell from the TSM that the 62 trans is the same as the 63 (M-35). The 61 is definitely different -- uses a vacuum modulator instead of a TV cable.

i had todo an engine swap on a 61 classic cross country a year and a half ago. was going to just put in the 196 out of my parts 62 classic 2 door. the torque converter wouldnt go onto the crank of the man trans 196 from the 62. had to pull the crank out of the 61 196, and put it in the good 62 196.

Don't worry about the trans flange unless it's pre 62. 61 and earlier use a cast iron center section, 62 was the first of the aluminum trannys, and I know for sure they use the same flange as manual cars -- I've swapped 63 models between auto and manual. I'm not sure if the  57-61 Borg-Warner used that "volcano" crankshaft or not, but I don't think so. Pre 57 Ramblers used the GM Dual-Range Hydramatic -- that uses the special crank. As far as I know ALL the Borg-Warner autos use a flat flange crank, same as the manual trans.

HOWEVER there was a funny 195.6 automatic trans crankshaft in some 
years. The 232, and manual 195.6's, the crank flange is mainly flat on 
the end, with a recess in the center; but the funny 195.6 auto butt has 
a large raised volcano in the center. It sticks up a good inch, and is 
rough-cast around the volcano slope and machined in the top for the bushing.
