1998 Windstar 3.0 engine with the U vin
code, 229K original engine and AXAS transmission.
I have posted on other forums on this issue without any results. I realize this is a Taurus forum but the 3.0 in the Windstar is not very popular so I am asking for help here.
When driving in town and after making turns, accelerating the engine will ping. When it pings the transmission does not shift down, upon letting up on the accelerator and then accelerating again it downshifts. ( acts just like the old tranny's with the vacuum solenoids for shifting) This does not happen all the time but quite frequent.
Work I have done.
Complete fluid and filter change
New Spark plug wires and spark plugs
New Ford TPS
New aftermarket TRS
NO CODES (Laptop with OBDCOM software)
My next move is to replace the Transmission speed sensor or the VSS
Would having a transmission shop check for codes do any good? Would their scanner read any codes that my scanner would not detect, Are the tranny codes all PXXXX????
No speedometer, cruise control issues.
Any thoughts, thanks
