You are thinking of the transmissions for diesels. They have a 4.25 ratio
compared to the gas 3.89 ratio. The interesting thing I found is finding
documentation that can back it up. Here's a list of the Bentley and Haynes
service manuals I have and what they list for 4 and 5 speed diesels:
Bentley 75-79 A1 3.89
Bentley 80-84 A1 3.89
Bentley 85-92 A2 3.89 and 4.25
Haynes (US) 74-84 3.89
75-89 none listed
75-92 none listed
Haynes (UK) 74-84 3.89, 4.06 and 4.57
Only the A2 Bentley and the UK Haynes list alternate ratios for diesels.
The others still say that diesels use the 3.89.
I don't have the Bentley 77-84 A1 diesel manual so this may have the
key information.
