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

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!

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.

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.

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.
