98 continental shifting erratically

[32valvelincoln]

new to the front wheel 4.6, and new purchase shifts erratically. happily replaced vss today, and new brakes on front, test drove and it is just the same. cruise worked b-4, did not test too frustrated that trans still shifted wrong. any ideas besides the vss? thanks

Could be the MLPS braking down on you, what is it doing exactly?

Thanks for your response, it shifts fine 1-2, but 2-3, it just starts free revving. I can punch gas 2 or 3 times and it will shift to 3, and then 4 pretty normally. wot, it does about the same, winds high, shifts very hard with tons of torque steer. I have seen a lot of valve body replacement rumors on this tranny.

make sure it has enough transmission fluid.

ok will check fluid level today, it is clean and pretty clear actually not very red at all light pink at best, but I did not check while running. thanks

tranny fluid would be bad

The AX4N is a pretty stout trans. I've had a lot of experience with the AX4S and wasn't expecting much when I got my 2003 Taurus. I have to say I've been very impressed with it! I bought it with a "bad trans" so I did a lot of researching before I pulled it apart. There are only 2 problems these transmissions are known for, most common being the torque converter drive strips requiring a reman converter. This is what mine needed. Next is a valve (iirc) that acts up on the VB. I looked into replacing this part but it seemed a reman VB was the best choice to make sure you didn't have to pull the trans apart twice...

I agree with what Chris said though, I would check the level with the car/trans at operating temp on a flat surface first. Good luck!
