Gears

meirikm · January 17, 2021

Hey all, I spoke briefly with a guy at a local performance shop here re trying to unlock more power without breaking the bank. I already have an intake and programmer. I did the muffler delete. I’m honestly not too interested in upgrading the exhaust. Unless I can find one that’s super smooth sounding(doesn’t sound like a tractor).

anyways...he mentioned that I could swap out my gears... does that make any sense? Would it make a noticeable difference? If so, how much would something like this cause and what would a good ratio for city/highway driving?

thx in advance

I forgot to mention I’m RWD...not sure if that makes a difference or not..4:10, eh? Does that prioritize low end acceleration?

have the tuner reprogram the transmission. stock is horrible. I have zero engine performance parts, but am slowly tuning the A6 trans , and i swear it feels like i added 15hp by reducing slip, tcc poins, TM, an cooling to 135 F

gears are great for towing and off the line hole shots and shitty MPG. stock is 3.42, which sux for running 35" tires, but in stock trim its great for city and highway MPG, and top speeds with stock diameter tires

Mpg was no change for me, 2wd truck will be cheaper by about 1500.

Ok, sounds good. Would it be worth it to do the rears? I think I can control shift points etc with my programmer. Tbh I’ve never really played around with it. Just set it to 93 octane

I first did tune and trans tune. Wasnt enough for me. Gears was a best hit before a trade to diesel. U have to make tht decision. If u have it i would do it. Especially if u tow.

I don’t tow but I always have tools and stuff in the back and a heavy ass speaker box. I’m guessing about 1000 lbs ish above stock weight very other day or so.
