Well, 6 speeds in FWD cars are somewhat more complicated than in a RWD.

You have to look at the final drive 1 (3.238) for 1st, 2nd, 3rd, 4th and final drive 2 (2.615)for 5th, 6th and reverse. over simplified, final drives are dual rear end gears, what must considered is overall drive ratio per gear.

Here is the speed in gear chart for 5th + 6th all speeds are mph
RPM 5TH 6TH
5500 161.14 193.93
5000 146.49 176.30
4500 131.84 158.67
4000 117.19 141.04
3500 102.54 123.41
3000 87.89 105.78
2500 73.25 88.15
2000 58.60 70.52
1500 43.95 52.89
1000 29.30 35.26

created with Gear-Speed Calculator Program

Hope that helps, hit me up if you are still confused, took me a while to wrap my head around it also.
