The transmission was rebuilt recently. Shortly after the car was wrecked and sat for a while before I got to fixing it. Since then I have had problems shifting from first to second gear. Year ago it did that and stopped after adding tranny fluid. This year it is doing the same thing but the fluid level is good. Took it to Aamco and they said I need to replace/rebuild the Valve body gone thru. I have found a valve body kit on-line. Just wanted to know if it is something I can fix myself. Called another mechanic and was told it is few hours of labor for them to replace the valve body. Can I just buy the valve body kit and replace it on my own? Have moderate skill level in mechanical. Any special tools or procedures for this type of repair?
