Problem has got me.1990 XJ6 drives great some of the time until the little engine light
comes on.When it comes on the transmission sticks in high gear,which makes for a
real problem if I am going up a hill from a dead stop.If I stop put it in neutral turn off
the engine and restart the engine it will ,most of the time clear up (not always).I am
thinking it is something electronic in the transmission.Is this a problem with the 1990?
