I have a 2001 Honda Accord with the 3.0 v6 and 135,xxx miles on it. Currently I am out of the extended warranty but I do owe another 4 thousand on the car. The shifts are either way too hard, its getting stuck in 3rd and not downshifting or upshifting, its obvious to me that the tranny is on the way out. What I am looking for is tips on what I should do. Whats the difference between a rebuilt transmission or a completely new one, really just need another 25,000 miles on this car. Will getting a flush help me at all or is it too late?
