i am looking to put 3:73 or 3:55 gears in my automatic 1990 SC and i was wondering is this something i can do. if so how easy is it or would it be better to take it somewhere to have it done. if so what type of place should i take it? the dealer? well any info on this would be great. oh and by the way which gears will i notice the most performance gain with? thanks
 
Take it to the shop.....

If you do it yourself, you will need to be able to set up the new ring and pinion gears to the correct tolerances with a feeler guage. It's not worth the hassle or the pain if you don't do it right (it will be noisy and wear prematurely).

Take it to s respected repair shop. If you can't find one, then maybe go to the dealer.

Good luck, and go with the 3.73 if you want the most performance.
