I did a little reading about Subaru trannys and I've got a few questions for those who know anything about these beasties. 1) Will any tranny that came from an EJ series engine bolt on to any other EJ series engine (in particular from a EJ22 car to a EJ25) ? I know gear ratios and strength come into play, but I'm just asking about the physical fit. 2) Does the manual tranny (5 speed) have any sort of electronic interface, or is it purely a passive mechanical system ? 3) For the auto tranny, it sounds like there is NOT an available part to convert AWD to FWD, right ? So I guess that means finding a FWD tranny. Anybody know what kind of electronic info is required to control these ? I think I read that some Suby trannys have an input to control the shift points based on RPM and pedal stompage. I wouldn't mind coding this in MegaSquirt, but I have no idea what kind of I/O the tranny expects. 4) srbliss : Have you got your conversion parts ? Any comments ? FWIW, my long national EBay nightmare is entering week 8. Supposedly I have a fresh EJ25 engine that has progressed from NY to a loading dock somewhere in Michigan, but I've got serious doubts..... WIsh me luck. |

1) I "think" any trans from "any" EJ series engine will bolt to "any" EJ engine, some have 4 bolts and the newer ones have 8. 2) The 5 speed has 2 swithes on it. I would guess one is for the reverse lights and the other is neutral switch. No other wires on the trans. 3) I don't know - I do know that lots of FWD autos were made, even the 6 cyl SVX came in FWD. 4) I have not got the parts - still sorting out payment to Australia, looks like Paypal is the way to go. CV joints are "supposed" to be a no brainer as the splines on the Subaru shafts are the same as the 914. I don't have my shafts yet so I don't know for sure if this is true. Steve Good luck on getting your engine. |

Take a look here for Subaru service manuals. Loads of information on the automatic control stuff.

Here's the question I have... How do we shift the damn thing? I know that cable shifting shows much potential...
One thing that concerns me is that I would like to use dog engagement on gears 1-4, whether I get to or not is a different story, and solid linkage is the only thing that really works for that. So... is it possible to fabricate a series of pivots that would allow the use of solid rod linkage? |

Like I said earlier - I plan on using the stock style linkage with the Subaru transmission. I don't see why it can't be done.

I was talking about the manual transmission shift linkage. The auto should be a snap, just use the Suby lever and a longer cable to move the lever on the trans. I am pretty sure they use a simple lever to shift it and not a nest of motors and wires - I hope so at least.
What did you use for axles on yours??? |

I came across this page by a guy putting a Suby tranny in a Spyder. It has some useful info including pictures and measurements. One thing that I had never seen clearly was the shift mechanism. From the pics, it looks like this is a "tail shifter" (which is just what you'd want for a front-mounted engine.)
Info on Subaru Transmissions BTW, I saw this in a forum that might be useful for people reading this thread : Subaru Transplant Forum @ USMB |

Time to bring this to the front again.
I am having a hard time seeing how the cv's actually hook up. are they the 914 or the subaru cv's that are actually used? I have a wrx motor that i am putting in my teener and i am going to try to put the subaru 2wd 5spd in with it. this may not be the best tranny but it is worth a shot. i can get one from an early 90's legacy for cheap. |

here is a view that might help, not a 914 but an approach

That's exactly what I am thinking along the lines of. Might need to use a u joint or 2 but, it should be fairly simple.

Ohhhh. Thats nice. That would make the dog gear shifting possible as well.

Old car....... older driver Group: Members Posts: 514 Joined: 10-July 04 From: San Diego Member No.: 2,332 Region Association: Southern California |
Does anyone know if the output shafts of the Suby trans are in the same vertical and horizontal planes as the Porsche trans? If not how much are they different? I'm not sure how much constant angle a CV joint can take on a continouus basis if the locating points are significantly different. Also I haven't heard a good explanation (either) of what CV's, axles, or adapters are going to be required. Anyone???
