2001 Windstar Transmission Slip
I have a 2001 Windstar with 112,000 miles and the transmission is slipping in first gear. Reverse, 2 and 1 work well. When shifting from R to D the van will sometimes roll a little until the transmission engages. Once in D it will move forward in idle and with very little acceleration. However, once I accelerate normally the engine revs and I go nowhere. This might happen once or twice before engaging normally. If I start in 2 and then shift manually to D everything goes well until I stop. Trans fluid was full. Had fluid flushed a few days ago. Still no help. Went back to the shop and there are no codes. Any suggestions?
