Greetings,
I was wondering how 3.73s would work in my '95 automatic SC. It has full SCP exhaust including coated headers, 5% pulley, 180 degree tstat, and an Apten chip. It runs very good right now, but I recall sometime back, someone said they put in the 3.73s in an automatic, and said it felt like the car lost 500 lbs. I also wonder about cruising RPMs, gas mileage, etc. With the chip, duration between shifts is longer, and I'm afraid of over-revving in 1st gear. Any problems? I am hoping it turns out to be a fair tradeoff, because already, my car gets some scratch in second. Thanks for comments, suggestions. By the way, having your automatic flushed and filled with Mercon V is a great idea. Better cooling properties. I just did mine at 94,000.
