Automatic Transmission feels like as if I was driving manual and clutch slips on 1999 Toyota 4Runner

When I turn from a stop I believe I hear something not catching. This problem just started. It is just like driving a manual transmission with a clutch that is gone. This happens when I am at a stop and then go, once I get going I from anywhere from 20mph-40mph (I have n0t tried pushing it past that)and step on the gas to speed up it has that slipping feel

Within 2 months. Not sure if it could be a torque converter problem or solenoid issue?
most likely internal clutch issues or converter. how is the fluid level?
Fluid is fine. When I am in reverse I do not have this problem.
