I read somewhere that the internals and tail shaft from a mopar 518 aod trans, will swap into a amc 727 case. Has anyone done this yet?

There was info on this on the old website, It will not work the back of the case is different.
Someone on the old site did make it work but he did it by cutting the amc bell off of a Amc 727 and the mopar case from a 518 and welding it back together. That is not for the faint of heart and you really need a machine shop at your disposal in order to make that work.

I have a 45 RFE overdrive trans in my Javelin but it is bolted to a 2004 Hemi. This is a huge transmission and I had to section the trans tunnel to get it to fit. A lot of guys are going with the Gear Venders overdrive since it bolts up to the 727 easiely since the tail housing on the AMC 727 is actually a Chrysler part, while the front case is AMC specific. The overdrive unit can take lots of torque and aren't all that expensive compared to a complete rebuilt or good condition donar overdrive trans. Gear Venders units are pretty popular in the muscle car crowd for many makes.

"It's possible to perform this conversion with many Mopar, 1972-'78 AMC and two-wheel drive Jeeps that were originally equipped with a Chrysler 727 transmission." Exactly how is this done on the amc 727? |

I know they wrote that, they are assuming that amc's used a chrysler bell housing bolt pattern. But it was there own pattern. Yes it will work with a mopar becuse you can unbolt the 727 and the 518 will bolt right in. I have a 518 and a Amc 727 and belive me you can not bolt the overdrive from a 518 to a standard 727.
Some jeep grand cherokees did use a amc bell auto overdrive, but it a overdrive version of the 904 and is not as strong as the 518 Edited by 71gremmy - Jul/23/2007 at 11:21pm |

Can't happen.
The author didn't research before making a blanket statement. The only OD torqueflite with an AMC bolt pattern is the 42RE that came behind many 4.0 Grand Cherokees only. Besides being a fully electronic trans requiring a controller to operate, mechanically it isn't up to the task of a V-8 much less the 6 cylinder it was bolted to. |

but it is on the internet! I don't recall the guy on the old forum actually getting his working - I think he had the trans welded up and then never came back. His project looked promising! |

I know, I know if it's on the net it's fact. Just like the enquirer as a newspaper. |

I'd have to agree with PMM here........He's just stating the fact's..........as he said, just because it's on the internet or the media, doesn't make it correct........there is really no OD that will work in place of the 727.........518 will not fit the AMC engine! if you want OD and your 727, get a gear venders OD.
