Tc Or Gears
If someone can afford one or the other what would you do with an auto and 2.73 gears.Put in a high stall TC or change the gears and why.

BUT.... I would not hesitate to do the TC only if the number$ were better... Can you not do both? I would think that the labor on both at the same time would be less than the two at different times given the work...

A T/C may involve installing a tranny cooler so keep that in mind. But you will need to get your car reprogrammed with the new gears unless you are going from 3:15 to 3:42's so there are costs involved both ways. Just something to think about when push comes to shove

Wow...im gonna have to eat it on this one!!! Can I ask some of you the gains you recieved from doing a gear swap only compared to those of you who have done a converter swap only? Track times only please, no SOTP. I'll start...2.73 car with a 3200 2.5 converter. Went from a 12.99@108 1.99 to a 12.47@108 1.77 with only changes being the converter, trans cooler, and a transgo shift kit. This was in a 99 z28.

GEARS...BUUUUT save a little while longer, and since you're paying the same labor, go ahead and get both...i think it'll be worth the wait.

Especially if you plan on doing the other in the next year or so.

Do both at the same time - it will cost you twice because the labour is the same for gears or stall.
I went from 2.73:1 and stock TC to 3.90:1 and Yank SS3600 stall
Night and day difference. Love it.

Gears would be best if you can only do one, but I agree that you may want to wait and do both at the same time.

Since I was tearing it down anyway, I decided to go "all in". We did Yank 3600 converter, trans cooler, transgo shift kit, and 3.42 gears.
I also had some transmission tweaks using LS1-Edit....quicker shift points, higher red line rpm....
I run at 2400 RPM at 78 mph on the interstate. In my MN6's I run at 1800 at the same speed.
I would recommend though if you go higher than 3.42 that you research getting the hardened shafts too.
