Good morning,
This could be many issues. Testing needs to be done to find out what has failed.
There are procedures I attached that should be done to narrow the area of failure. Chances are you have something that failed internally in the transmission.

Line Pressure Test
CAUTION: Carry out the Line Pressure Test prior to carrying out the Stall Speed Test. If line pressure is low at stall, do not carry out the Stall Speed Test or further transaxle damage will occur. Do not maintain wide open throttle in any gear range for more than five seconds.
NOTE: Certain sensor failures may cause high PC, FMEM (Failure Mode Effect Management) actions. Make sure that self test and electrical repairs have been carried out, or test results may be incorrect.
This test verifies that the line pressure is within specifications.
1. Connect pressure gauge to the line pressure tap.
