E4OD- While driving it seems to "freewheel" as if manual transmission would kick out of gear. There is not set frequency but does at random. Shows no codes Usually occurs 40 mph or more and often at interstate speeds. Filter and fluid change 6 weeks ago, problem was occuring before change also. Today when drive re- engaged kicked in a bit hard- weather does not seem to effect this event. Any ideas?

I would take it to the trans shop find one you can trust. It could be a torque convertor or a solenoid or convertor lock up problem. Thanks

Took to transmission shop locally, they beat around the bush and said it needed a complete overhaul said there would be filings on the magnet, when fluid changed found none, shifts ok, was hoping one of the techs would have experienced this.

It will more the likely be a torque convertor but with out a pressure test you don't know for sure. My 95 F-150 doesn't have this problem it does have a shift kit and shifts firmer then most but no problems with the lock up. With my info it say's with you problem it is either the torque convertor. Now to test this I need you to drive the truck and at 50 mph you will need to pay close attention to the rpm so hopefully you have a factory tach. Now you will need to use your left foot to do this. Now at 50 mph you will take your left foot and lightly tap on the brake (not enough to try to stop it just like you are riding it for a second or so), the rpm should increase for about 5 seconds if it doesn't then the torque convertor is possible bad or the brake switch may be bad or even the tps could cause this or better yet the MAF sensor. Let me know what you get and we will test a couple of sensors from there ok.

Did the 50 mph road test, first brake tap revs were approx. 1750 and momentarily went to 2050-2100. Drove approxamatly 20 mile trip and suffered no freewheeling, however later in the day took a 14 mi trip and it occurred again. Still no check lights. Doublechecked fluid level and just for giggles checked all electric plugins.

Ok that seems to be working now has the trans been checked for fluid pressure? I would have this done to kill the possibility of needing anything major. Maybe we should check the VSS vehicle speed sensor and the TPS. Get back to me with what you would like to do and I will get the test for that.

This may sound kind of strange, but you might want to have the transfer case checked. I have a 1990 and had a simular problem. It finally just stopped going period. Had it checked out and the transfer case had come apart inside. Just an idea
