Re: [AMC-list] Yet more Borg Warner auto questions

[Frank Swygert <farna@xxxxxxx>]

If the 68 Rebel is a six cylinder, it has a M-37. That would have an aluminum case. If the postal Jeep has an iron cased transmission it is an M-11, otherwise it's an M-4x. They are similar, but the iron case is of course a lot stronger. 

The 290 uses the same bell as the 232 IF the 232 is 1972 or later. I don't recall if the bell for the small V-8 and six auto trans is different in depth or not, I think they are the same. Converter would be different stall, but that should be the only difference between V-8 and six. For a stock vehicle I wouldn't be scared to swap them. The transmission should bolt to the bell though. 

If you have a fixed yoke on the postal Jeep trans, you will need a two piece driveshaft. Other than that there should be no problem.

The console is the same for auto and stick cars. The plate on top and the boot underneath is different, that's all.

I determined that the trans in the '68 Rebel is an M35 (I think?) The one from the Postal Jeep ('75 vintage) is different inside. Maybe M11? (going from casting numbers) 
?? Whoever worked on the Rebel's trans last put a regular o-ring in the piston and it canted in the bore (likely from being adjusted too loose) blowing the ring out. There was a ton of aluminum sediment and clutch material in the pan, so I guess this trans is a goner. 
?? Does the 290 use a different bell than the Postal 232? Converter different too? (the 6 cyl one has a long skinny pilot) I have the Postal one next to the 2wd AW4 that's going into my Spirit. Of course, the length is different because the postal one is a fixed yoke (Ujoint bolts to it) but when I get the one in the car out I'll compare it with the AW4.

?? Bottom line: Will the bell from the '68 Rebel bolt to the Postal Jeep trans? Will I need to change the torque converter too? (after flushing of course) How hard is it to find a flywheel for a 290? Would the console have to be changed to run stick or is it just a boot under the same console?
