auto to five speed in a 73' 240

[doug73'240]

has anyone succesfully swapped a auto with five speed in a 240. if so, i'de like to know what year transmission would work, and everything i will need to get from the manual car. Also any links would be nice.

Thanks, doug

Doug, I think you can use any 5 speed thru 83, you need the trans, mount, pedal, new holes in your firewall and all the linkage, and backup light stuff, there's an article about where the shifter comes out on this site, but I believe if you use a Z trans as opposed to a 510 it will line right up. I think I have all that stuff at my wrecking yard by the way.

Doug, I asked the same question a few months back. Ken laid out the part you need. I was told that the 5sp from the early 280's (up thru '78) had gearing that matched up better with the early 240s for what that's worth. I was also told that most 5sp trannys need to be checked out before installing them. Apparently, folks drive around in 5th gear and blow out some important bushings or bearings. Now a used 4speeds is reportedly less prone to this damage. Food for thought. Good luck partner!

go to this site for a run down on what is involved by someone who has done it before.

Doug , if you do the swap I am looking for a flexplate with a good ring gear . If you have one for sale let me know. Thanks Gary
