Hi,
First post here as I am trying to find out what I have and what I should have on my 69 AMX. I am pretty sure it has an AMC shifter but I don't think the floor hump is correct. I have seen the diagrams of both types from the TSM but if anyone could post pictures of both that would be most helpful? Also, are parts available to rebuild the AMC shifter? Thanks in advance. All the best Sandy P.S. I may need lots of advice in the months ahead. |

The "AMC" shifter used a metal hump. The Hurst shifter used a plastic hump.
I've never rebuilt the AMC shifter, but I've read that it is very similar to, or the same as the same year of Ford Mustang shifter. So Mustang parts may work for a rebuild. Best to check the Mustang parts catalogs & see what is offered & if it looks the same. |

The original shifters were mad by a company called Inland Tool and Manufacturing. The main thing is to make sure it is adjusted correctly, and that is done by the sliding pivots on the transmission arms. The main thing that can break on these units is what is called an interlock washer, and it goes in between the reverse lever, and the 1/2 lever. this keeps the transmission from going into reverse, while still in 1st or 2nd gear. it has a small tang on top, and slips into the shifter body, to hold it steady. I have rebuilt a couple, and parts are not listed for them anywhere, BUT, they use the same repair part as fords shifters, made by the same company, so the washer is available from several sources. If you want one, I have a couple spares, as I thought they would be hard to get, and I discovered differently. You can find them lots of places for 15 dollars, plus shipping, but I sold a couple of my spares recently for 15 dollars, and included shipping in the lower 48 states, higher elsehwere, as I found a few in bulk for a decent deal. Another thing commonly missing, is the large Beehive shaped spring, and snap ring, but again, same as the fords.
Shifter rod inserts and clips are available from multiple AMC vendors here on the site, and others, I have used AmarkAMC, to find parts, including the original type knob and retaining nut for it. Do you have a picture of your shifter, to make sure it is original? I am assuming you do not have an aftermarket shifter, like a Hurst, right? Factory shifter used from 1966 to 1969, AMC and AMX cars, for reference. Edited by Cricket - Aug/26/2016 at 5:33pm |

Thanks. That's a helpful photo and great information.
I think that is what I have. The car is in pieces (I need lots of bits too) and not yet at my house but here are a couple of pictures I took. I don't think the 'hump' is correct based on this illustration I found on line:- But all advice and photos appreciated. Sandy P.S. I live in Scotland. |

The pic from the parts manual is probably out of a Marlin or Classic. The one in the pic you took is the correct one for an AMX or Javelin. Keep in mind, many of the pix in the parts manual are generic and don't represent the actual part for every application.
That hump is not in the correct position in your pix. Edited by 71SC360 - Aug/27/2016 at 5:02am |

Sandy,
I think you have the correct shifter and metal hump for an early 69 AMX. The hump is not correctly positioned, but since the screws are removed, I'm guessing it's just sitting there. You can see where the screw holes in the floor are, it just needs to be installed. The reverse light harness is correct coming from the front of the shifter hump, it connects to a 2 conductor wiring harness that lays along the top of the trans tunnel from under the dash. The early 69 shifter was made by Inland Tool & Machine as was the shifter for early Mustang T-10 4 speeds, so parts are available from CJ Pony Parts or other Mustang suppliers. It's not a difficult shifter to rebuild, if nothing's broken, a good cleaning, lubrication and reassembly will have it working as well as it ever did. Which was not that well, hence AMC's change to the Hurst shifter in mid 69 and later cars. One of the main complaints about the ITM shifter was 'looseness' or sloppy shifting, it was sometimes called The Mystery Shifter. I'm working on a partial solution to that problem with a new, improved shifter handle for ITM shifters that eliminates the sloppiness of the original worn shifter handles. Keep an eye on the "New Products" section for availability. Meantime, Good Luck with your AMX and show us some pictures when you can. Terry |

At one time, I used a shifter handle from a mustang, as they have side springs and buttons. This eliminates the sloppiness, and gives a better shift. Honestly, I have one now, and when I get it all cleaned up, I am going to sell it. I'll post a picture when finished.
