my 2.5l will make me drive at 20-25mph befor it wants to shift but it shifts to 3rd it feels like i can make my gear selector drop to 2nd and i can get in 2nd that way but it jumps from 1st to 3rd i can start with the selector in 1st then go to 2nd then drive no problem but it slams trying to go from 1st to 3rd what could be a consern i just serviced it after it started doin this and the o/d lights flashes sometimes
