I recently bought a 89 turbo automatic 2 weeks ago,been sitting around a year before I bought it.I bought it knowing it needed some work in the transmission department,so i finally got it put on the computer tonight.The codes that I am getting are #62-#1 solenoid valve;#63-#2 solenoid valve and #53 knock sensor circuit.What do I need to do to fix the 2 transmission codes?Any thoughts or suggestions would be greatly appreciated.Thanks everyone!
