Getting off topic here,but I think it depended on what transmission a vehicle had.
The intent of T.C.S. was to provide vacuum spark advance during high gear operation ONLY,because eliminating vacuum advance in all but the forward most gear significantly reduced exhaust emissions.
Cars equipped with T.C.S. and either a 3spd.M/T,4spd.M/T or Turbo-Hydramatic,only had vacuum advance applied in 3rd gear.(The 4spd. also had vacuum advance applied in 4th gear too.)
Cars equipped with T.C.S. and either a Torque-Drive or Powerglide trans.,only had vacuum advance applied in 2nd gear.
Any T.C.S. equipped Turbo-Hydra also had vacuum advance applied in reverse as well.
