No, you didn’t buy a lemon, although, at times, it might seem like it. Your minivan is seven years old and it has 80,000 miles on the odometer. This isn’t a great deal of mileage as averages say your van should be at 105,000 miles but it is still a pile of miles and your minivan is a bit tired. With that said, though, at this time in a vehicle’s life things do start to go.
The good news here, though, is that there probably isn’t anything major wrong with your transmission. The most it is likely suffering from is a case of slightly low automatic transmission fluid (ATF). The fact is that your minivan is exhibiting a classic case of slightly low ATF.
Your minivan’s automatic transmission requires a certain amount of heat to operate correctly. The manufacturer, in fact, designed and built the transmission to work in this manner. The ATF uses this heat to expand to fill all spaces in the transmission properly so that it will work correctly. Now, if the transmission fluid was down substantially, your transmission would have lots of trouble finding and keeping a gear.
You will have to fix this problem, of course, to ensure the transmission performs correctly. To do this, you will have to get a good reading of how much fluid is missing and then replace it. To obtain a reading, take these steps:
1. Find the transmission dipstick
2. Park the van on a flat surface, put it into park and set the parking brake
3. Start the minivan and let it warm for about 20 minutes (or you can drive it for 15 minutes if you prefer)
4. Holding the brake down as an added precaution, run the minivan through all gears, holding each one for a moment
5. Pull out the transmission dipstick and wipe it with a clean rag
6. Replace the dipstick and withdraw it carefully again
7. Take your reading. Be sure to look at the level between the HOT marking
8. Add exactly the amount of transmission fluid that needs to be replaced. An automatic transmission doesn’t tolerate overfilling at all so be as exacting as possible
9. Replace the transmission dipstick and you are finished
