GMstomper said:What RPM range are you lookin at with 3.55's or 3.73's on AOD car...same as a T-5???
Actually, they're about he same. .68-.70 O/D gear._JB_ said:The RPMs would go a lot higher...well maybe not a lot, but more than the T-5
With 373's and an aod , at 80mph, Im doing exactly 2500rpm !! At 70 Im doing 2300,,and at 60 Im at 2100,,thats with a stock tire size!GMstomper said:Went from 2.73's to 3.27's and loved it. May go higher now that I'm starting all over again (she was in hibernation for 2 years!) and shes not my dily driver. But I'm not sure about it with the AOD...dont want to burn thru second and third too quick. Also concerned about my cruising RPM's...especially since I have a problem driving under 75 on the highway. I keep driving faster the older I get. LOL
No, the AOD has a taller overdrive.Highbredcloud said:RPM's will be higher with the AOD since the AOD only has 4 gears with both the 3.55 and 3.73's...the RPM's will be lower with the T-5 since it has one more gear...

2500 @ 45mph in OD? I need to rethink gearing my aod (don't have the car yet). That is horrible. I don't know how to convert the numbers off the top of my head but wouldn't that put you well past 3000rpms at only 60mph? That doesn't sound right to me but I don't have experience with aods so...Highbredcloud said:Before I converted my AOD I ran 3.73's...at 45MPH I was doing 2500 RPM while in overdrive...with my Tremec I'm at 1900 in 5th gear...that extra gear helps out with a rear differential swap.
