Philabuster,

Sorry, I don't know the gfear ratios in the 5 speeds but the fifth gear is overdrive. There are some of the SL and SLC gearboxes that are 5 speeds but the 5th gear is not overdrive, therefore they must be closer ratios. They are hard to find and the SLC & SL boxes are very expensive. Too bad you're not closer as you could come by and drive as manual turbo. I'm sure you'd give it some real thought when it's time to repair the automatic! Cheaper and faster.
