petroski Posted October 1, 2006 Share Posted October 1, 2006 Greetings all, Anyone out there ever replaced the front transmission seal in an old style, 1979 4 speed? How much trouble was it? Thanks, Ski Quote Link to comment Share on other sites More sharing options...
SUBARU3 Posted October 1, 2006 Share Posted October 1, 2006 What seal are you referring to? Quote Link to comment Share on other sites More sharing options...
petroski Posted October 1, 2006 Author Share Posted October 1, 2006 The mainshaft seal. I've never had to replace one before. This will be the second engine rebuild for this wagon, so its got a few miles on it. and the trans is leaking ( I'M TALKING ABOUT BIBLICAL PROPORTIONS) from behind the throwout bearing. Clymer shows installing the seal with the mainshaft during final assembly. I believe I would buy good a used trans before I dissassemble this one to replace a seal!

SUBARU3 Posted October 1, 2006 Share Posted October 1, 2006 Well, I would consider a replacement. You have to pull the trans to do the seal anyway. It's a job to split the case. Not impossible, but certainly not fun. Why not upgrade to a 5 speed? You just have to replace some of the shifter linkage. ....pretty easy. I'm sure other will chime in here.

Todd 5 speed 4wd hooked to an ea71, is the fifth gear overdrive or 1-1? Quote Link to comment Share on other sites More sharing options...
moosens Posted October 3, 2006 Share Posted October 3, 2006 I was going to ask but it seems you answered.....yours is 4WD already,right? I'm pretty sure Todd meant that if you have the old four speed FWD tranny that an upgrade would be the 5spd FWD from a GL,or Coupe,etc. Quote Link to comment Share on other sites More sharing options...
SUBARU3 Posted October 3, 2006 Share Posted October 3, 2006 Paul...your right. I assumed it was a FWD. Todd Quote Link to comment Share on other sites More sharing options...
moosens Posted October 4, 2006 Share Posted October 4, 2006 Yeah,for 4WD unfortunately that's a case splitter if it's the main shaft seal.Looking at the manual makes me want to rip one apart.Sooner or later I'll be needing mine done too. I'm pretty sure you can search for an '80 1600 4WD too,if you search online.Just have to make sure it's the top starter. Quote Link to comment Share on other sites More sharing options...
