These days I'm driving Mike's 1970 teener since I broke my 73. With no radio I get to listen to the sweet sound of the 1.7L behind me and I get lots of time to think (probably a dangerous thing!).(IMG:style_emoticons/default/wacko.gif)
So I got to thinking about transmissions and I remember someone commenting that there was a cable-shifter available from Patrick Motorsports, but that even though it is better than a stock side-shifter it still isn't as smooth as modern transmissions that were made to be cable-shifted. It being that Kennedy seems to make adapters to fit anything, is there a cable shifted transmission out there that would be a natural fit for a 914? (Of course you probably have to flip the ring gear.) Subarus come to mind as a possibility just because they have flat-4 engines, but I have no idea about anything else about the cars. |

Anything will fit if you have enough money...
I have heard less than complimentary things about the Patrick cable-shifter. This was quite a few years ago, now, and they may have gotten the bugs worked out of it. The install was on a 915 gearbox attached to a 3.0 Six, and the owner said, "I really should have just stuck with the side-shifter. Better shifting, easier install, and much cheaper." You can try a Boxster trans. Rumor has it that it's the same as some of the Audi FWD ones. Most other transmissions either turn the wrong way (e.g., 911 boxes), or do not have a differential in them (e.g., most RWD transmissions), or are set up to be transverse (e.g., most FWD transmissions). The Audi and Scooby trannies are the only ones I can think of that are FWD boxes mounted longitudinally. Saab might have some as well... If you're willing to flip the R&P, then most of the 911 boxes will work. As will Bug/Bus/etc. Note than in many cases some machining to the inside of the box must be done. In some cases, most of the important parts of the box have to be redesigned... But it will work, if you throw enough money at it. --DD |

The more exotic transmissions are best suited for large HP motors. Stick with the 901 until you have to go differently.....unless you LIKE throwing money into something like that.
DD, that's your best side.... |

The FWD 97-99.5 tansmissions from a FrontWheelDrive Audi A4
or VW Passat are very similar to the Boxster transmission. Probably cheaper to come by also. Gearing will of course be different to the Boxster. Also the cable shifting gear will bolt right up to the A4 or Passat transmission and apparently the stock cables are very nearly the perfect length so no modifications need to be done there. |

I thought the Passat had a transverse drivetrain, like the Golf/Rabbit? If so, that wouldn't be such a great donor.
ZF made some transmissions for cars like the Pantera and other mid-engine'd cars with various motors. Some of them were transverse, but some (like the Pantera, I believe) were longitudinal. You might be able to hunt one of those down and adapt it. But why? (IMG:style_emoticons/default/wink.gif) --DD |

I have a 911/02 (pull clutch version of a 901. MY's 70-71, 911) that I'm thinking of using in the GT project. I e-mailed Bruce Anderson regarding it and he stated that Chuck Stoddard used one in a 6 conversion:
QUOTE He used the 911 transmission case so that he had the pull clutch mechanism. Then he just used a 911 clutch cable to pull the clutch arm. I haven't gotten to that side of things yet. I'll probably need a little more info as I dig into it. In the end it's basically a 901 anyway. I have both the original side shifter and that tranny out of my 71, 911T to make things work. If anybody has any insight on Chuck conversion I'd like to know more. |

The '97 up Passat has a longitudinal transaxle (as does Audi). The 1.8T uses a code EZG (mostly) 012 transaxle, which has ratio's slightly closer than does the 5 speed Boxster. 5th gear (net) ratio's are the same for both. For the Boxster guys; where is the starter mounted on the 5 speed car? Fore or aft of the bellhousing?

Good thread!
I'm trying to figure out the best way to stuff a TDI motor in a 914 and have been wondering what would be the best tranny and gearing to use. Any guesses on how a Passat drivetrain would fit? |

The Boxster tranny wont work. The starter comes in from the front of the bellhousing not from behind. Unless you run an engine in front of the tranny that has a engine mounted starter (on top).. no go.
The tranny on top is a 915.. the lower tranny is a BoxsterS 6 speed. B |

Are you saying a 944 tranny can work? How? Doesn't it output to a rear driveshaft?

Brad,
Does this discussion relate to your desire for an automatic 914.....Im thinking if the Audi tranny fits....mmmm lots of cheap A4 automatic out the in the bone yards... R |

As far as a TDI goes, if it will bolt up to the boxster,Passat,A4 tranny
you could use that option but I am not sure that gearing would be what you want with the diesel characteristics. Scott(SKSfrom Audiworld.com) put in a 350hp 1.8t with an Audi A6 front drive tranny(similar to the A4's) and used the boxster cable shifter assembly and said that it worked out pretty slick. |

Rich, those are just tranny's sitting around here that I snapped quick shots of.. The problem with all the Audi tranny's is the same as the Boxster, unless you run a Audi engine or 986/996 engine a starter solution is damn near impossible. They have NO provision for a rear mount starter. The KEP Audi automatic adapters are for V8 engines with (tada..: engine mounted starters)

If you delete the torque tube from a 944 engine/tranny would be short enough to fit in a 914?
cheers, Jeroen |

There is a UK company that uses the 944 tranny's in a replica GT40 with a V8 in front of it.
I think the 944 box would work fine.. I know it is a Audi box also. B |

I have to see an A4 tranny...Im thinking cut off the front of the bell housing and mount the front of a 914 bellhousing to it...
Sounds simple but I need to see a tranny to see if that would work.. I just watched RIDES the new TV show and watched them do exactly what I am talking about.. The guy band sawed off one bell housing, mad a plate and bolted on the other bell housing.. This would give us a place for the starter. There are plenty of 914 tailshifters collecting dust, so bellhousing should not be a problem. Then you could get an automatic 914.... If someone has an old dead A4 tranny, I would be glad to make up an adapter/bellhousing unit to make it work, then we will have an automatic 914 solution that is affordable. If someone has a pick that would help..if not I will check the local bone yard and see if I can get a dead one. R |
