injection pump leak

[jpliddy]

hi all
well i got the car back but to late to check leak is ok they tell me all is ok now .
but driving home i noticed in low gear the auto was hesitant . then i noticed going up steep hill the car was staying in third gear i think never done that before . could the problem be anything to do with the adjustment they have made . i may be over thinking all this with whats gone on the garage said they had fixed the cold start tooset it up .
can there now be other issues going on cold start.kick down .gears change playing up , if so won't go back to that garage ,
