98, Explorer 4.0 Code comes up every 260 Miles as a miss shift and its on the dot every 260 miles what could cause this to happen. Help

 

Change your route, the truck is getting barn shy..

 

Just kidding, are there any codes??

 

I cant remember the code but it means miss shift I know that much. If I unhook the battery it gos away untill it hits 260 miles.Any ideas

 

only code that I can think of is the 1-4 shift solonoid, and I dont know why that would be distance related. Need more DATA!

 

That's probably your warning to get the problem fixed.

I'm just guessing, never having owned a vehicle with a slushbox full time, but letting solenoids go to hell can't be good nor cheap to fix in the end...

Unhooking the battery is not helpful, either, since the computer has to relearn its shifting patterns, which is also not gentle on the tranny. Even the easy way (pulling the ECM fuse) does the same thing.

Ooops.

Anyway, the Haynes has several shift solenoid codes, among other tranny codes, but you didn't give us enough to narrow things down with.

 

I will have to code pulled again when it comes back on.
