Hey Scotty I drive an 82 ford f100 automatic with 5.0 v8. So far it has been doing well however, recently it started to make what I can describe as a "whirring" sound upon acceleration. The sound completely stops around 20 mph which I'm guessing is when it shifts to the next gear. It doesn't do it while in park or neutral if I rev the engine. Hopefully it's not the transmission. I was thinking maybe the alternator? It kinda sounds like a remote control car..

Well a reputable trans shop can help to rule out the trans, most do free evaluations if you wanted to try that. If possible you could drive it shortly to see if the whining stops after removing the accessory belt(s), if it's still making the sound, then it's either the trans or engine internals.

Thanks I'll have to check that out! Also what is the possibility of it being the powersteering pump? I siphoned out the fluid and put transmission fluid after reading youre supposed to use f type fluid in it along with some Lucas oil additive for power steering and it seemed to dull out the sound a significantly? Thanks again!

can't be the alternator, it would do it in all gears. Probably the tranny going out, do this test to find out for sure https://www.youtube.com/watch?v=pqh1oH8mEqY
