What is my gearbox telling me?

[OldBlue2002]

I’ve removed and cleaned my 5 speed gearbox. Looking at the pictures I took before cleaning it, does the location of sludge make anyone think of a particular seal failure? The grime was mostly found on the rear section. I did find a loose bolt in the circled picture.
Also, my research tells me that the three section gearbox is a Getrag 245, but there is a 242 stamp inside the bell housing and a date stamp of 79/80. Thoughts?

Whenever I pull a gearbox,  I always replace the rear engine seal,front and rear trans seals and the shift rod seal. Probably wouldn't hurt to to snug up case bolts.  Be sure that the breather is not clogged.

Great to hear. I just did a new oil pan gasket and rear engine seal and do have those three seals for the trans.

Also replace the lock ring for that rear flange nut and, the plastic pivot for the throwout bearing arm,if it's worn.

The new selector seal is in and the correct front seal is on order. After getting the rear output nut off, I can’t seem to pry off the flange.

Sometimes requires a puller. Most parts stores rent or loan them.

Thanks everyone. Input, output and shift selector seals have been replaced.
