1999 Cadillac STS, transmission & hidden main sump drain plug
#21
This is an old thread, but for those who want to know, the main sump drain plug is over by the shift linkage(driver side) side of the trans. It is visible with the lower pan removed. It takes a 7/16" socket...just a regular 1/8" pipe plug. I can get a pic and post it later...
Anyhow, i heard anywhere from 7 quarts to 12 quarts after pullin that plug, how many qurats is it roughly if anyone knows...
