4l60 which was the new name for 700r4.
You either have 273s or 323s. Gu2 means 273 and gu3 means 323 if I remember correctly. Look for the code on your glove box door.

93s got the 4L60 (sans E), same as the 700R4.

shbox

GU2 : AXLE REAR, 2.73 RATIO

GU4 : AXLE REAR, 3.08 RATIO (V6)

GU5 : AXLE REAR, 3.23 RATIO

GU6 : AXLE REAR, 3.42 RATIO

According to what I have read on other boards from transmission rebuilders/vendors, the 700R4 and 4L60 are not exactly alike with regard to all internals, but very similar.

Cool thanks for answering rear end ? Now should I overhaul my tranny or go for the th350 or th400? I want around 600 rwhp

Get the 600 hp first, then get back to the tranny. And if you want 600 hp get prepared to yank the engine out for a rebuild because there's no way the stock bottom end will survive.

Yea I was planning on that and throwing a yank in. I hear a rattle from near the tranny but it might be that the torque arm mount is broke could that be a reason? It almost sounds like the tranny goin out or the drive line shaking. Don't wanna have to switch the tranny. For a cheap part. Thanks for all the help.
