If your going to the trouble swapping gears. Also swap the low stalling stock converter while your car is apart. A hi stall T/C like the Yank SS3200 or SS3600 will make a HUGE difference in performance. Excluding nitrous a hi stall T/C is the most bang for the buck in an A4.

I have RPM 3:42's, RPM Level IV Transmission & a Yank SS3200. Car has great street manners and yet when you step on it it's like lighting a rocket!

A stock 2.73 auto is a hopeless slug. Before I learned anything about C5s, I rode in a pristine auto C5 and it was so slow I truly thought something was wrong with it. That same car later had a 3.42 gear put in it with requisite tuning, nothing else done, and I could hardly believe it was the same car. Before the gear swap, I raced him with my newly-acquired C5 manual and walked away from him. After the swap he could usually beat me, 'tho it was more a case of me struggling with that miserable C5 manual shifting than his car actually being quicker--when I did manage to hit the gears right I could edge him out.

I do understand your reasoning for not doing it. I will add though that the extra torque that you'll get from the 3:42's can be enjoyed when leaving every stop, not just the strip.

Thanks again for the information. I found the part on GM Parts House. I like your suggestion. That's what I will do with mine next. I will keep you posted on the result.
