Which one of these is better for the swap for my 3800SC Sunfire and why ? I've heard kinds of stories about Hp ratings, Shift points, etc... I can't get my car to launch with the 5-spped, so going to an auto will get my gear ratio better out of the hole. Why will hate giving up the 30+ MPG at 75mph though...
You might wanna check with who's done the swap using an auto. But The 4t65-HD would be best if it will fit into the car easily.
