Can it be done?

-
This is a complete transmission swap from a 904 or 727 to a500 or a518. They are selling the kit to make the newer a500 or a518 work right in a non computer car. I don't think there is any way to turn a 904 or 727 into overdrive witha few simple steps. If there was we would all be driving around with it. :):)

p.s. also all the work is setting up the the newer tranny in the tunnel.

What he said , you can't turn a 727 or a 904 into an OD trans unless you bolt a gearvendors to the back of it , that link is as he said , how to put a 500 or 518 into the early mopars , CUTTING is required .
 
are you sure? cuz down lower on that page they have a part with this description:

PATC 727 to 518 Conversion Kit
#727518. With these four parts you can convert your 727 transmission to a 518 overdrive transmission with locking torque converter. [FONT=Arial, Helvetica, sans-serif]Lets say you drive an average of 400 highway miles per week, at that rate you could save as much as $1000.00 per year on gas, not to mention the 31% reduction in RPM. Your new 518 will have automatic shifts into overdrive and lock-up, no toggle switch needed. Now with adjustable vacuum switch. The instructions are at the bottom of this page. [/FONT][FONT=Arial, Helvetica, sans-serif](11-25-06. I just saw this kit on the Internet by the copy cat competition for $1654.00.) [/FONT][FONT=Arial, Helvetica, sans-serif]C[/FONT]
[FONT=Arial, Helvetica, sans-serif][/FONT]
[FONT=Arial, Helvetica, sans-serif]sounds like a conversion, since thats what it says. but maybe im just not reading it how i think i am?85.0[/FONT]​

Am I sure ? ABSOLUTELY . There is a picture of the 2 trans side by side on that page , look at them , no way you can do it without sawing the 2 cases apart and welding the back of the 518 to the front of the 727 and there ius absoultely no reason to do that , with a smallblock , because you end up with the 518 case anyway except now it's two halves welded together.

Yes , you are reading it wrong , wishful thinking on your part. They are selling you the parts you need to INSTALL a 518 where your 727 was NOT converting a 727 to a 518 , that can not be done .

Edit , I just read the thing you are mentioning here , all they are selling you is the parts in that picture next to what you posted above , those are the parts you need to make a 518 work properly as OD and the lockup convertor are both actuated by solenoids inside the trans .

You need to go back and READ the ENTIRE page that you linked and get out of your mind that it's turning a 727 into a 518 , that page is all about REPLACING a 727 with a 518 .

well damnit they should rewrite that then! haha o well i can dream of o/d, cant i? i hate the premise of having to hit a button for o/d like the gear vendors $3k part....just want it to kick in automatically like it would on a regular new car
 
The parts pictured for that kit (pressure switches, throttle switch and a vacuum tee) are what is required to get the 500/518 to shift to OD and lock up automatically, not convert a 727 to a 518, similar to what the text in the beginning of the link references doing. I think they worded it incorrectly, should have been more like "allows you to install a 518 into your 727 equiped car and still have it shift automatically".
 
The guys are right. The A518 may look like a 727 but the rear part of the case is actually quite different so there's no possible way to convert a 727 to a 518.
 
:eek:ly C?@! You guys are awesome. I just wish there was some way to forward the info to my E-mail:prayer: does anyone have pics of the required mods for the A 500 series transmissions
