| Post subject: | 4 speed OD linkage question |
Not sure if anyone can answer this question easily but I figure I would try here before I call Passons or someone similar. I picked up an A-833 OD truck tranny that I will transplanting into my slant six powered e-body, I am preparing to have the rear mounting holes drilled and tapped so that I can move the shifter to the rear tail housing location. The question I have is, I know the levers on transmission for the 3-OD are inverted on the OD trans but is the linkage the same (I assume if the linkage is same for the b-body/truck mounting point the linkage would be the same for the rear e-body mounting point). So in short, can i just pick up a set of e-body 4 speed linkage for the A833 to work for the a833OD tranny? Brian |

Somebody correct me if I am wrong. Only the 3/4 shift rod is inverted which means you need a different linkage arm. 1/2 and Reverse should be the same however 3/4 changes based on whether or not the transmission OD or not. |

that is correct, i am just curious since 3/od lever is really just the 3/4 lever inverted on the OD case if the linkage arms are the same and the arm needs to be inverted to work, or if the angles are incorrect and it would require more than just inverting the linkage rod. I may end up calling Passons since I believe they over 4 speed OD trannies as part of their services now. Brian |

The shift rod is a different length. |

When I go home tonight I'll compare a 833 with a 833 od, but I don't see why the e-body rods wouldn't work. It kinda makes me wish I still had my other 833 e body trans with pistol grip still lying around just to see if they will really bolt together. We got rid of almost all of the e body parts a little over a year ago, but a few things were misplaced and I don't think I have the rods anymore. |

Dangit mcnouple, how am I gonna put your old car back to the way it should be if you dont have the parts for me to do it laying around. Didnt you have an OD trans in the car when you owned it or just a regular A833? |

| Post subject: | be careful regarding your shifter mount |
Hello all! Here is a twist on 65Dart...and a comment he is right! Out of rank ignorance when missing a shifter mount plate to start, I got several different mount plates from several different A833OD's. This is because the tranny got used in lots of applications. The GM plate fits a Hurst Competition Plus at a different angle relative to vertical than does the Mopar somewhat oval one. Te Reverse rod, in particular, thus has the most variation in length in my experience. Rod lengths for car applications can vary widely depending on how much curve is put in to get around crossmembers. Trucks can use dead straight. The easiest thing to do is measure up what rods you have and see what you may yet need in length. I have a stash of rods and can probably fit you if you know your lmissing length. I also found the angle of the plate relative to vertical didn't matter much to shifter operation.....I was trying to cock the shifter as far forward as possible so I could have no bench seat interference with the shifter handle. You can visualize how a mount plate angling the shifter relative to vertical will dramatically affect the reverse rod. It is really pretty easy to make a custom mount plate too out of some plate scrap, and then just mate whatever rods you have to the shifter. Oh when you drill that cast iron, go slow and use a good lube as in the kind used for tapping. Iron is easy to work but doesn't like high speed. You are basically worrying out pellets instead of turning a dual spiral from the drill point. rock '64d100 |

Rock, Thanks for information. I have the complete setup shifter, shifter mount for the b-body truck location, and I have bucket seats in my challenger so I was figuring I could just use the hurst shifter and the shifter mount that exists. I will have to wait til I mock up to see if I have any issues with the cross member. Brian |

If it becomes difficult to get the linkage it's not too hard with a little patience and a welder to create your own linkage rods. We went a little overkill on the Dart and used 3/8 rod. It works great though, I've never had a problem with any clearance issues. The main reason we went ahead and built our own was because we were having a hard time finding rods for an OD in a '65, ours are all placed over the crossmember. Caleb |

When we had it it was always a 3 speed. When we still had the challenger we also had 2 73 340 4 speed cudas. One was a cuda the other a barracuda but the options were identical. The cars were never reassembled and we sold them and the parts collection for the e-bodies to one guy. So now from time to time I will stumble across parts for an e-body, but some things like a spare trans I know exactly where they are. At the time I had planned on putting a 833 into my V100, but I only want to weld a floor in once so its T5 time. I thought you were getting a t5 bell made up for it with the rest of us.

I am getting the t-5 bell but that doesnt stop me from being impatient and wanting to put one more gear in at a time lol. I will probably skip the 4speed OD and jump to the t-5 I was just wanting to tear the car apart again so the wife can't start driving it. I dont know I am about to get into my new three car garage and wanna start tearing something apart and the challenger is close by, the swinger and panel truck are both 4 hours away so I don't get a chance to tear into them until I get the challenger is buttoned up and I can bring one of the other two up here. |
