Re: Do you have to remove AutoBox for flywheel seal replace Posted by SWEDECAR [Email] (#112) [Profile/Gallery] (more from SWEDECAR) on Sun, 17 Nov 2013 08:30:31 In Reply to: Do you have to remove AutoBox for flywheel seal replace, al, Sat, 16 Nov 2013 14:01:22 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Assuming is always a risk and especially with a monumental labor intensive job like that.
Yes, lifting out the power train and separate engine and transmission is the proper way to replace rear crankshaft seal. Not easy at all.
But the quinky dink is that it could also be the paper gasket between front and rear transmission housing that is leaking.
They did a really weird design in that a very small portion of the engine crankcase oil compartment stretches into the front transmission housing and the whole paper gasket seals that together with also sealing the rest transmission housing.
I have seen the gasket withered away allowing motor oil to leak out close to the flywheel area under the starter.
They could just as easily have skipped the tiny void in front housing and blocked off the engine oil compartment with aluminum wall in rear housing and not had this problem at all.
It is another "dirty" way to get the torque converter out but it is still a giant amount of labor and some risk involved by disassemble the front housing and oil pump through the back and lift converter out. But I'm not sure the flex plate can be removed after that to reach the rear seal.
This was a trick used when the oil pump drive tangs had broken off the converter on a fairly ok transmission and it was just a matter of sticking another torque converter in there.
