Have a Jetta with 238K miles. Bought car at 120K & serviced transmission, then at 180k and now at 238K. If I leave it outside in the cold (below 30 degrees) it takes 5-10 minutes before I really can drive. Before then it doesn't want to shift smoothly. When cold you can put it into reverse and it won't move even if you give it gas, takes 5-10 secs of giving it some gas and it might shift hard. I keep it in the garage due to this issue. My other issue is once it's warm if I give it gas (to get out of the way of other drivers and not get ran over) it may hang in the present gear, might have to shift manually until I get up to speed. I also have the issue if I try to drive it pedal to the metal it stutters doesn't want to accelerate if giving it gas. Really not sure what to do?
