Transmission Fluid

How can you tell if transmission fluid has been mistakenly used for engine oil if after only 3 days it is black?

Smell it! Transmission fluid has a distinct odor. If you have any doubts, then I would immediately drain the crankcase and replace the oil and filter. Otherwise you will ruin an engine.

Either someone put transmission fluid in the oil filler or the transmission fluid drain plug was mistakenly opened instead of the engine oil. In other words, transmission fluid is red and engine oil should be amber to black in colour. Note some automobiles use red fluid for power steering as well but usually don't have a drain plug for that.

You should never add transmission fluid to a Chevrolet 350 engine. You can add transmission fluid to the transmission through the transmission dipstick holder.

NO!!!! do not do this, oil is oil, transmission fluid is transmission fluid, and antifreeze is antifreeze, do not mix any of these, it can perminately damage your engine.

The transmission dipstick is at the center rear of the engine comparment behind the distributor. This is how you have to fill the transmission fluid as well. DO NOT overfill the transmission fluid, that is the quickest and easiest way to damage a transmission. Transmission fluid is to be checked on a warm engine, idling in park.
