I want to put new gears in my GT. So far my mods are just C&L intake/tune, and FRPP stingers. I was thinking about putting in 4.10s but the speed limmit out here is 75 mph and we often drive 90-100 mph. I think 4.10s would be too much. I was also told 3.73s would be a bit much for those type of cruising speeds. I might go with the 3.55s but I worry if I'll even see much of an improvement. Does anyone have any experience with these in an auto??

Thanks for any input.

if your gonna do an upgrade and youactually wanna feel something go at least 373, i have 4.10s and 80-90 is no problem. 3k-3.5kish...go FRPP for gears!

+1 on the Ford Racing gears, I am getting 3.73 installed in a couple of weeks, I think 4.10s would be a little much for a daily driver.

Thanks for all the input. The car is "supposed to be" my wife's daily driver, yet I'm already modding it. I just want to make sure it will still be a good daily driver and highway cruiser.

You will be happy with 3.73's. They will be just fine at cruising speeds. I run about 2500rpm at 75 which is perfect. Nice pick-up from the stock 3.31's.
