2000 TL Won’t Go Into Reverse

All-I’m having some issues with my DD 2000 TL. Ive been having multiple issues for the past month. It all started with the P0780 code. Got the TCS light and flashing D5. I replaced the 3rd gear pressure switch. I then did a 3x3 trans flush using Honda trans fluid. Things were fine for a little while (20 miles) then got the TCS and flashing D5 again. I damn near overheated the engine on the way home from work. I cleaned the shift solenoids and cleared the codes. All the lights are off but I now have one slight problem. I can’t go into reverse. It’s like the car is in neutral. I also checked the coils and all are good. Can anyone help me out? I appreciate it!
