Its not engaging into the right gears. When its in park, I put it into drive to go and the engine just revs high and doesnt go into gear. So I have to keep reving it into it pops into gear. Also, once I get it into 1st gear, it shifts through the rest of the gears fine.

It has 130,000 miles on it and I dont know if the oil and filter was ever changed. Im going to do an oil and filter change and see if thats the problem and then go from there.

Also, what is flarring?

Thanks
