tranny issues?

[mstng86]

I have never had a transmission go out so I am not sure how it feels. Our expedition started acting us yesterday. I was on the highway and was cruising at 65 ish and and then felt the car shift lungeing me forward very lightly. The rpms dropped a couple hundred and then goes back up. The wife said it is doing it around town now.

Any help would be great.

most likely.
knew a guy that rebuilt his trans because of the same issue,still didnt fix it.
ended up being a few wires.

I was oing to say it idles fine. So change the ignition coil and see how that goes?

[greenbullitt]

2000 should have coil on plug (8 coils) if i remember right..you need to find which one is the issue and replace it...

It is coil on plug. How do I troubleshoot which one it is?

without a check engine light set, you will need a shop to perform a cylinder balance test would be the easiest

I guess I will leave it up to a shop then. I don't gave the right tools I'd knowledge and I don't like playing guessing games

without a cel, itll save you money and time to pay someone a diag fee to tell you

[mstng86]

Yea, there is no CEL. I can change the coils, if I know which one it is. The only one that looks like an issue is the furthest one back on the passenger side.
