hops Posted April 9, 2004 Share Posted April 9, 2004 Are all like transmissions ( 4wd, 2wd, auto) interchangeable with all models that use the EA 81 engine?. Example: Will the 4 wd transmission from a ea81 brat fit into a ea 81 4wd wagon? Thanks a bunch for your help. Klaus Link to comment Share on other sites More sharing options...
GeneralDisorder Posted April 9, 2004 Share Posted April 9, 2004 Yes - with sometimes a LOT of work. Other times nearly none. Like transmissions are the SAME. But 2WD vs. 4WD are not - neither are Auto's. The difference is in the floorpan sheetmetal. Going from 2WD to 4WD is sometimes difficult.......

DJ_Kuehn Posted April 9, 2004 Share Posted April 9, 2004 hops, If you need one I have still have that tranny i posted the other day with only 26,000 miles on it. Link to comment Share on other sites More sharing options...
AKIRA Posted April 9, 2004 Share Posted April 9, 2004 there is a difference in gearing between 83-84, but they fit in all the same. Link to comment Share on other sites More sharing options...
CIS Subaru Posted April 10, 2004 Share Posted April 10, 2004 I don't think this is an issue here, but just for general knowledge: You cannot connect an '83+ Auto tranny to a manual tranny EA81, nor will it fit on a pre-'83 auto tranny EA81. The '83+ auto trannies (2wd and 4wd) require either the special engine bellhousing from the engine they came on, or grinding of the engine bellhousing you have.

mcbrat Posted April 13, 2004 Share Posted April 13, 2004 Noah, not sure I follow you. where does the grinding need to occur, and why? I have gone the opposite way a couple of times....

MilesFox Posted April 13, 2004 Share Posted April 13, 2004 i put an ea81 in a 2wd 3spd ea82 car, and i had to grind away a lot more than yout typical 5spd setup. the motor was from a 2wd 5spd, noah's point ...

hops Posted April 28, 2004 Author Share Posted April 28, 2004 Do you still have that tranny? how much would you want for it? Klaus Link to comment Share on other sites More sharing options...
mcbrat Posted April 28, 2004 Share Posted April 28, 2004 I believe the tranny that DJ has is a 2wd auto if that makes a difference.... Link to comment Share on other sites More sharing options...
hops Posted April 28, 2004 Author Share Posted April 28, 2004 Yes it would make a difference. It will not work. Klaus Link to comment Share on other sites More sharing options...
DJ_Kuehn Posted April 29, 2004 Share Posted April 29, 2004 Hops, just sent you an email. I believe it is a 4WD automatic, but I'm not positive on that. It has a shaft coming out of both sides on front, whatever that means. Sorry for sounding like a moron, but I only use these motors for my hovercraft projects. I'm not familiar with the transmissions at all. Link to comment Share on other sites More sharing options...
mcbrat Posted April 29, 2004 Share Posted April 29, 2004 DJ, the stubs out both sides of the front are for the front wheel. if 4WD, it will have a spot for a rear driveshaft in the back. In your original post about your tranny, you said it was a 1980 ea81, and all the 1980 4WD had the 1600 ea71 motors... Link to comment Share on other sites More sharing options...
DJ_Kuehn Posted April 29, 2004 Share Posted April 29, 2004 McBrat, you must work for subaru or something... you're always responding to my posts with good answers to (what i consider) obscure questions! (thanks, btw) Well then, this is for sure a 2WD trans. It is a 1980, and it does not have a shaft in back. Link to comment Share on other sites More sharing options...
