i was having transmission issues, this is at idle. i have reverse, but in drive or all forward gears disengage and engine revs slightly when shifting to drive also my speedo moves up to 50 mph when i give it gas. then i got a p0172 code.
so, i replaced all 3 o2 sensors with Walker brand. had to replace the exhaust after cat to rear of car. i also replaced all 6 shift solenoids with a new aftermarket brand. Also, both valve bodies were rebuilt. also replaced both speed sensors aftermarket brand and new neutral safety/range sensor. new fluid and filter.
i disconnected both battery cables before work was done.
when finished i drove it for 3 drive cycles then all of a sudden it reverted back to same symptoms as before work done. i checked everything out then did the battery cable thing, then drove it again for 2 drive cycles and it reverted back again. but when i did drive it it drove great. strong. great shifts up and down. like normal except for a little hard shifts and such as per relearn.
so today i reset PCM by battery cable way and now i still have reverse but drive disengages again.
i have an Ancel fd500 scan tool with ford system scan and came up with 201 systems scanned. It also scans transmission systems.
i have those live data results if needed.
What could be the issue here?
Oh. I also bought a remanufactured ECU/PCM programmed to my VIN with the latest update.
