It does sound like it's low on fluid.  To make sure put in into each gear a couple times and check the manual for the proper level check procedure.  Some transmissions have to be checked with motor running and in neutral, others cold with engine off.

Good luck.

Checked fluid in park with engine running same thing today almost no reverse but in drive hits pretty hard was not like this in summer,tranny seem to engage pretty hard either way. modulator valve controlled shifts??  "old school thinking"This weekend hope to drive it on the backroads to warm up trans.
