Re: Yank SS4000
so a 4k stall and 4:10's on a 100% stock motor....wtf. Lower gears I can see but a 4k stall on a stock motor...might want to consider something closer to 2800 or lower. TC stall and cam specs are what you want to match
If you are not doing this work yourself it can cost some $. Rear gear swap is generally $250-$500 labor if you supply parts. Trans shop likely charge at least $500 to R&R trans to put in a TC. Plumbing in a cooler, IDK but assume shop hr labor rate times x hrs

Re: Yank SS4000
Most A4 owners opt for 3.73 gears, to keep at least part of the benefit of the O/D 4th gear ratio (0.70). With 26" tires, 3.73's will cruise at 70 MPH at 2,360 RPM. With 4.10's RPM jumps to 2,600 RPM. I run 4.11's with an 0.78:1 O/D. Cruises close 3,000 RPM at 70 MPH with street tires - not a lot of fun. But it's a "track" car, not a daily driver.
The idea of the stall is to put the engine into it's peak RPM range for a potent launch. But a totally stock LT1 in an F-Body is past it's peak torque at 4,000 RPM, and the torque is starting to nose dive rapidly. The LT1 has such a flat torque curve from 2,500 - 4,000 RPM that you would be much better off with a 3,000 RPM (or even lower) stall to maximize the "area under the curve".
As far as running 4.10's in the 10-bolt with a 2-series carrier, you can buy gears sets specifically for that application from several manufacturers. Here's one example
