RPM transmission. I have an RPM stage 2 diff with 3.73 gears. When my 4L60 goes, the car will get an RPM trans. Your c5 trans and diff is like the cars second most important part besides the engine. Don’t cheap out on it. Find an install shop that knows what there doing. They can probably have your trans out and a new RPM trans in there in a day or two. Slide a new torque converter in there while you’re at it. Converter like Yank, precision industry, or Circle D.

Good luck.

I second a RPM unit. I have a Level 5 and it is solid. Think about a converter as well. My level 5 was ~3500ish bucks with core if I remember correctly.
