Slipping transmission

[Paul S]

2000 Expedition, 4.6 Liter , 2 wheel drive. New fluid at 60,000 miles.

The transmission is acting funny. 1st and 2nd gear are fine, the shift from 2nd to 3rd takes a long time and the transmission slips into gear. The shift into 4th and overdrive are fine.

Does anyone have a clue what is causing the problem. It just started happening. The fluid was replaced at 60,000 miles.

Am I looking at a rebuild or merely a fix?

Thank you for any assistance, it is greatly appreciated.

how many miles now?

 

[Paul S]

At the present time there are 75,000 miles on the truck.

do you mean it revs high before it shifts? when is the last time you changed the gas filter

 

[Paul S]

The gas filter has never been replaced. The truck will almost redline before it shifts. It is very weird. all of the other shifts are fine and on time.

i worked on police cars and a dirty gas filter did the samething your discribing change it and see what happens

I will change the fuel filter this weekend. The problem has been getting a little better. It is just weird the way it came on all of a sudden.

Thanks for the help. I will keep you informed.

Just4fun......I replaced the fuel filter on Saturday. The problem is seems to be going away. The revs are not as high and the shift seems to come sooner. $16.00 and 15 minutes sure beats any transmission work.

I really appreciate your help....Thank You
