Speedo gear/Tranny question

I found tons of info on "what" gear to get. But the question I have is this, I am going from 3.27 to 3.73. I have the correct speedo gear. Will I have any problems with the tranny shifting? Will it still shift correctly? I am eventually going to get an SCT tuner but I dont have the cash for it right now. I am mainly concerned about how my car will react with the new gears and speedo gear. Thanks

I believe you might hit the rev limiter before it shifts, but I'm not sure. If the trans is j-modded, it may not be an issue.

it will drive the same other than the speed limitier will hit early on like 80 something mph. with a tune that disable the speed limiter then you're all set.

I knew that it would hit the limit due to the lower gearing, I was just hoping it wouldn't affect the shifting too bad. I will get a tuner eventually as i had stated. Just hoping it will be ok untill then.
