I have a 2008 Edge SEL with 55,000 miles. Noticed recently that there was a slippage between the 2nd and 3rd gear while accelerating. It wasn't bad, just that the RPMs would rev a bit higher than into 3rd it would go. It also stalled going up a hill one day from a dead stop and the "wrench" signal came on. Restarted the vehicle and it was fine. So, i brought it into the shop and they ran diagnostics and it came up with having to replace the TSS and OSS sensors. Has anyone ran into this problem and was it taken care of by replacing those sensors? Thanks, Tim
