Many Volvo 940 owners complained about the ist gear would not change to 2nd until the engine is warmed up. Some even have to stop for 5 minutes at the side of the road. However, once the gear change takes place everything seems to be ok until the engine stops for 5 or 6 hours. This is a terrible problem I faced as well over the last 1 year. Of late someone has passed this information to me.
He has the same problem rectified by adding a bottle of lubegard additive which is supposed to be friction modifier ( a black bottle). He is sure that it works although it is a month since using it. My question Does it work and hope some feedback.
