You can get the whole solenoid kit with the shift solenoids for around $100 on eBay. I got all OEM. I have put 100,000 on my car since I replaced the solenoids. The PCs is starting to act up every now and then but I have over 175,000 on the car with original transmission and motor so I can't complain. once you have the side pan off it takes about 5 minutes to replace all of them. I did the whole thing in about 5-6 hours with a floor jack and a few jack stands.
