Need help to identify year/model of tranny

I am in the process of replacing clutch in my 78 mod 930.

I have decided to go with KEP.
Before I order I wanted to be sure that the tranny is original an 78 year model.
Looked under to see the number and found "77Hq1521" also the number 12 as seen in picture and 36.

Part number on tranny is 930 301 311 0R

The clutch disc that was in it was a Sachs disk part nr: 1861 568 331
e-bay tells that this sachs part number is for 78-88
A google search showed it was for the 3.0 l 930 tranny





Know that the -77 and 78- are different

I'm not familiar with serial numbers for trannies and would just like to verify here.

Please help identifying so that I can get the correct clutch kit.


Also. What is the different between early and later 930 trannies ?

some more pics






Took out the old Sachs pressure plate with numbers:

3032 052 098 (099) not sure the last digit
TYP GMFZ 240

Can I assume that this tranny is the original from 78 ?

Based on the inside of the bellhousing this specific unit appears to be from an 86+ year model. Perhaps you can look at the date casting just above the shift rod.

Regardless, you definitely have the 78+ design which is commonly called a "long bellhousing". The 76,77 design called a "short bellhousing" is missing the first inch of material from the face of the bellhousing up to the first casting rib.
