shifting

[deathcharger71]

if i shift manually anyways, do i really need the attachment from the carb to the tranny? i dunno what its called but do i need it lol

[Jon Smith]

yes, unless you have a manual valve body
it regulates line pressure you'll kill the tranny without it

[ChargerRob]

Just out of curiosity, what exactly is deathcharger71 talking about? 

[Jon Smith]

does he need a kickdown linkage

[andy74]

the throttle presure rod,that goes from your carb to the trans linkage,on an auto controls the line pressure and shift points-run with out and you will break stuff in a short period of time

got it, my new tranny is gonna be a manual valve body but i guess until then ill keep the kickdown on there. does anyone know what cars the A-999 came in? wrangler, cherokee...? what years? it seems to be a much more hard to find tranny than the 727, but would be an easier swap for my 904, i could find one in a junk yard if i knew what car it came in and what year. one more question, could i get a 4 speed tranny with a manual valve body? and which tranny would it be?

You mean the A-518 overdrive auto with lock-up (follow-on development of the A-727), right...not the A-833 four-speed?  You would have to also get a lock-up converter for that tranny and I don't think there is as much availability for custom specs on those pieces as there is on the non lock-up 727 gear.

The A-999 was introduced in '74 for use behind the 360 so you'll find them in just about any 360 powered passenger car after that (unless it has a 727).

John, wasn't the A-999 still a three-speed?  I thought the A-518 (46RH) was an A-999 with lock-up converter and the extra overdrive gear set?
