Need Help ASAP!!!!

[93hotrodlincoln]

I was pulling on the highway yesterday in my mark and it felt like it missed a gear at 60 when it shifted. I checked the fluid it is new and good and now the car seems to stay in first gear for a long time and seems to be very slow. When I get on the gas at about 50 the motor will rev to Like 5K and start to hook a little and it gets to 6K and stays there.

It will rev high and seems like the tranny is barley hooking.

Thanks

I have the same problem, just at about 30 mph...i checked the fluid and the same, looks great, added a lil motorslick50 or whatever it's called and its a little better, people talk about the Jmod, check out the boards for that

Do you get and rumble feeling like going over a wash board?

You've been warned, anything other than Mercon V is a big no no. Was your filter changed as well? Symptom of 1-2, and 2-3 accumulator replacement needed.

No, it it dose not feel like it is slipping and trying to grab. It will stay in first gear WAY too long under normal acceleration and if I get on the gas at about any speed it will rev like it is in neutral and not go anywhere. It has mercon V and a new filter.
