Me and my wife just bought a 99 e320 with transmission problems. We changed the conductor plate and 13 pin plug. Cleaned everything with electric cleaner and it drove for a few minutes then just gave up. It will rev and hold in place while in reverse and just holds in all other gears. Will roll in N. Can anyone help up with might be the problem? We put in Valvoline high miles for Mercedes. It gives code p0700. No others.
