Here are possible causes.
Vehicle Will Not Move Or Slips In "D", "1" & "2"
Incorrect fluid level or line pressure, damaged line pressure solenoid, control valve assembly, N-D accumulator, reverse clutch, high clutch, forward clutch or the low one-way clutch.
Seems the transmission has failed internally. Check the fluid level first.
