2007 toyota camry v6 automatic transmission has 202,214 miles. The car will accelerate by itself and not pick up speed sometimes. Scanned the car and codes
P0746 Pressure Control Solenoid "A" Performance/Stuck Off
P0776 Pressure Control Solenold "B" Performance/Stuck Off
P2714 Pressure Control Solenold "D" Performance/Stuck Off
came on should Buy and replace the solenoids or is there a way of diagnosing what the issue is?
I would say replace the solenoids and pray. Because if that doesn't fix it, it would mean generally that the transmission itself is just wearing out internally. Sometimes it will trip those codes if it's wearing out internally and it's not the solenoids that are sticking, but the actual internals of the transmission sticking which would require a full rebuild
How does the fluid look? Was it changed regularly? Have you drained it recently and looked inside the pan?
If it wasn't maintained regularly then the trans is probably done, and I wouldn't waste money in solenoids.
