Shops are swamped in my area to have diagnostics ran, so trying to find out what I can in the mean time. Bought Tahoe from my cousin, he said the transmission was replaced about 8 years ago.
Issues are whining when driving/accelerating and clunking when going (coasting) down hill at about 20-25mph…a bit of a clunk when going into park, drive, reverse etc. Seems to have lack of power. No slipping or grinding.
Any ideas?

Clunk in and out of gear could be U- joints or rear differential slop. Probably both.

Coasting clunk could also be those as things slow down and unload.

Whining could be spindle bearings or the aforementioned u- joints and rear differential.

Lack of power could be fuel pressure, gearing, and/or the feeling of switching to a more sluggish vehicle from a performance daily... like my swap to a Suburban from an 06 Maxima with the V6.
