The 186S was the standard engine for HK/T/G Monaro GTS, but the base Monaro had the two lesser engines (161 & 186) also available, the 161 being standard issue. I'm pretty certain that no GTS had a standard 186 engine when it left the factory. Also all of these had the 3-sp manual, 4-sp manual or Tri-Matic optional.
I'm not sure what you mean by "had a standard 186 fitted if they were automatic". Are you saying that you know of Monaro GTSs which have standard 186 engines fitted instead of the 186S, or do you mean that you could only get the standard 186 engine in a base Monaro if it was an auto ?
