A4OD problems

I am new to the powerstroke world. I have only owned my 96 f350 for a few weeks now. The truck has about 212k miles, and supposively the trans was rebuilt a while ago.

The other day I noticed it was slipping from 1st to 2nd. It would run up to about 3500 rpms and hold for a bit before slowly slipping into 2nd. It is also shifting pretty roughly into the other gears. The OD light was flashing. It is also acting like it is in netural at times when placed in reverse or drive. Or acting like the parking brake is on and will barely move.

I changed the trans fluid and filter yesterday and noticed that it runs at a lower rpm now and actually shifts thru all the gears, but still slips and shifts ind of hard.

Any help would be appreciated.

FYI the trans is a E4od. Is the od light still flashing? If it is you need to get the codes pulled, it's not good to drive the truck when the od light is flashing because the trans is in limp mode and builds excessive line pressure. You might try disconnecting the harness that is on the passenger side of the trans and make sure that connection is clean and dry. That connection controls all the shifting. Also is your speedometer working correctly?

How much is it bouncing? If it's just a couple mph it shouldn't mess with anything but if several mph I would check or change the vss on the rear axle and check the wiring going to it.

You might consider pulling it and making sure it's clean. Your right at that fine line that is, might want to replace it especially since they are not expensive or if you have a buddy with one and try it.

That is a good price, about $200 less than my rebuild but the builder did a lot of upgrading and a few extra's. If you don't have one already spend the extra money install a high quality over sized trans cooler.
