First -- ask yourself "what do I want to do with the car???"

If you are just going to drive around town and want to do the occassional burnout, either a 3.73 or 4.10 will do just fine...

If you want to all out drag race your car, a 4.10 and a good torque converter would be the perfect match...

If you want to supercharge your car, then 3.73 would be my choice...

If you want a higher top speed 3.73 would be my choice...

If none if the above apply to you and your driving habits, then stick with what you have now!!!

Good Luck and flip a coin to make your decision...

manual 4.10's auto 3.73's generally works well for a dd, the auto tranny is geared a little differently

 

i do what i can.

true4.10's will be a bit stronger in auto, but i got 4.10's in manual and wish i went 4.30. i also wish they wouldnt whine, but thats a different story. anyway, 4.10's are a good choice imo.

 

i noticed that people with 4.10s have their sig filled with performance mods and drag race. so i guess if ur going in that direction do the same or else go for the 3.73 which i recommend for daily drivers

 

+1, most poeple suggest 4.10's for a manual, 3.73's for an auto on a daily driver.
