Worn trans mount bushings? Or other issue
My apologies if this has been discussed. I might not have been using the right key words in my searches. So i'm hearing 2 distinct sounds coming from under the car when I'm accelerating at anything more than feather-light throttle.
Sound:
1) imaging a heavy wood table being pulled across a wood floor. That low frequency, strained grunt sound. I would hear this sound the most when my car shifts from 1‐2, accelerating at normal speed of traffic, especially while turning.
2) turn a plastic lowes bucket upside down on the floor and thump it with the handle of a hammer or large screwdriver. This sound occurs at tge 1-2 shift with a more spirited sort of acceleration. While driving, it's hard to pinpoint where the sound is actually coming from.
The car is a 1974 duster 318. TCI streetfighter 727. Not sure on stall model or size, feels like 2800ish. Just put in a fresh filter and atf+4. The old oil looked suspicious to my ignorant eyes. Smelled like normal trans oils, but it did have some pearl dust size metal fragments settle out in the catch bucket. Enough to where there was a thin layer across the bottom.
Ford 8.8 rear end
Not sure what other information is relevant. Thanks guys.
*Oh one more thing, the bushings on my trans mount look tired, and I don't see anywhere in the tunnel that looks to be taking a beating.*
