TH350 slow into reverse is usually a sign of hardened Low/Reverse clutch seals, especially if the slowness lessens after the trans has warmed up.

The correct way to fix the issue is to pull the trans and rebuild it with new seals and clutches.

I have seen folk change the oil and filter and add a trans seal softener like Lucas etc and it sometimes helps, but the results are usually short lived, especially in cold climates.

Doesn't seem to change cold or warm. I did try some Lucas and it has made a noticeable difference.
