Ford Taunus 20M (EU)

Automatic transmission fluid capacity & service interval

Ford Taunus 20M (EU) automatic transmission fluid capacity is 7 liters. Service intervals include normal use. The data covers 4 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Type	Specifications
Taunus 20M (2.0 ltr.- HC), P7b (1968-1971)	Use: Normal Capacity 7 liter Code: 3/1
Taunus 20M (2.0 ltr.- LC), P7b (1968-1971)	Use: Normal Capacity 7 liter Code: 3/1
Taunus 20M (2.6 ltr.), P7b (1968-1971)	Use: Normal Capacity 7 liter Code: 3/1
Taunus 20M RS (2.6 ltr.), P7b (1968-1971)	Use: Normal Capacity 7 liter Code: 3/1

All four configurations of the Ford Taunus 20M (EU) P7b series share an identical automatic transmission fluid capacity of 7 liters, spanning the 2.0-liter HC, 2.0-liter LC, 2.6-liter, and 2.6-liter RS variants across the 1968-1971 model years.
A 7-liter automatic transmission capacity is a relatively substantial fill volume, consistent with the total system capacity of a torque converter-equipped automatic, which includes fluid held within the converter itself in addition to the gearbox housing.
The 2.0-liter engine family within the P7b body is represented by two distinct variants, the HC (high compression) and LC (low compression) configurations, yet both share the same 7-liter automatic transmission fluid specification, indicating the transmission unit itself was common across those engine tunes.
The 2.6-liter RS variant, which represented a higher-performance trim within the P7b lineup, carries the same 7-liter automatic transmission fluid capacity as the standard 2.6-liter model, pointing to a shared transmission assembly between those two configurations.
All four rows are designated under normal use conditions, meaning the 7-liter capacity figure applies to standard operating environments rather than severe-duty or first-change-only scenarios.
