My 1998 Subaru Impreza automatic revs & thumps into gear when cold.
My 1998 1.5 auto revs and thumps when engaging gears when cold, have read in other forums about similar probs and some say a sensor problem?. Transmission has been replaced bout 10,000km ago by previous owner maybe didn't need to be but not sure. Seems ok later in day when hot, has had fluid changed with recent service
