3.73s in an auto?

I've got a friend that drove my car after I installed the 3.73s. He liked the extra power it seemed it give you plus the fun factor now. My car is a manual and his is an auto but he's wanting to put 3.73s in his car. I told him that he probably wouldn't feel as much pick up in an auto that he did in my car. Is this right and which gear should I recommend for him to get? BTW I've tried to get him to put a 2600 stall conv. but says he doesn't want to mess up the tranny. 4.10s with a 2600 stall conv. would be awesome, wouldn't it?

i would go with the 4.10's in a auto with a 3000-3200 stall.. 2600 is to low for the 4.6.. our motors dont make crap for power at 2600..

the way i figure out what converter too get is.. if the car was a stick what is the best launch rpm (figure for good traction) i think 3500 RPM works best for a launch point.. so a 3000-3200 is the best converter too get... th 3000 stall will flash too over 3400 durring launches and thats just perfect for the stock 4.6


if he gets a converter an gears... tell him to install a shift kit ( the shifts will get sloppy with the loose converter.. also he will need a good tranny cooler..

and with that he will be faster than you

Why would you install a shift light in an auto? Does the stall allow you to change the gears manually just without a clutch? I am in the dark when it comes to T/C and shift kits.

Shift Kit, not light.
