Default Can I just say 2.73's suck with a SS4000

I put in a yank ss4000 but have not changed gears yet to 3.73's so for now I have 2.73's I can barely get the car to move I have give it alot of throttle just to move. I can't wait for my 3.73's

With 3.73's and the proper "part throttle" shift points it will tighten up big time. I use 12 mph 1-2 and 22 mph 2-3. Works pretty well with that verter and the 3.73's....

2.73s suck no matter what stall your have i cant even imagine 2.73s, i have the optional performance rear with 3.23s and those even suck. 3.73s and a 9" are on the list of future mods

If you say so...

EDIT: I didn't catch that you drive an LT1. I imagine that 2.73s pretty much do suck behind one of those. The last LT1 I drove had 3.23s and could barely get out of it's own way (at least by my stuck up LS1 standards)

I can easily keep up with traffic at 2500 rpm with ss4000 with 373s. Whats it take with 273s?

Do you mean from a red light? If so, I'm either on someone's ***, or leaving the pack of traffic behind if I stay on the throttle to 2500 in first and second.

My ONLY gripe with 2.73s is that on the rare occasions that I go the track, the car shifts right before i cross the traps. If I was a diehard racer at the track, and didn't use the car on street much, I'd probably go with a lower gear. As it is, I rarely go to the track, and my car is my sole mode of transportation. I'm pretty happy with my "crappy 2.73s"

I like my 2.73's for gas mileage. I get ~20mpg mixed driving almost full bolton's and a 3500 fuddle.

I think the car would be quite a bit faster feeling with a 3.73 gear but I dont feel like I'm missing out. The converter alone got rid of that huge flat spot from ~40 to ~55mph and I can break em loose pretty much whenever I want. It took a long time to get used to it though. The first week after installing the converter I HATED my car. Stick with it and it will grow on you.

I had a vig 3600 with 2.73's for a while. Only reason I took it out was to help me get some of the funds needed to help me start my m6 swap. I sucked when I would get stop lights on an incline cause the car had to rev so high to get going. But you will get used to it, and when you do it wont be so bad. But 3.73's really help out in my opinion.

The problem with 2.73 gears and a 4000 stall is HEAT. You are slowly destroying your tranny. Get the gears first then raise the stall. The only thing that is prolonging the process is lock-up which stops the slipping. Think of your stall verses 2.73's. You are expecting to have a 4' prybar, but you really have a screw driver. There is not much torque multiplication. The result is alot of rpm or slippage down low which is creating alot of heat. If you put the correct gears in, the heat is dramatically reduced and the car has effortless movement forward. In other words, when changing parts on a vehicle, you must change other parts to match. You are reengineering your car to reach your goals of better performance. It's like a peanut butter sandwich without the peanut butter. Some of you might think your car is doing fine, but drive a car with the same stall and correct gears and ask yourself the same question. I'll bet those gears will be installed very quickly. Just an opinion.

I have the 2.73 as well in my currently stock '02 T/A. I read all this stuff about the different stall speeds and such and that it feels "looser" with the 2.73s vs say a 3.73 gear. Does the STR have anything to do with it? Would it be better to have a 2.0 STR vs a 2.5 STR with a 2.73 gear or vice versa? I too would like to hang onto my 2.73s for the mileage as I currently average 20-22mpg combined.

More STR is going to feel tighter pulling away from a stop when comparing converters of equal stall speed. But not many aftermarket converters are going to feel very tight with 2.73's.
