Tinkering with a 99 Suburban

[nathanadams16]

You've been busy. It looks sooooo much better!

Thanks, still a bit to do. As for cosmetics I’m going to strip the rattle can black off the bottom of the doors and repaint it to match my wheels.

I have always liked either silver or white rigs with black accents/trim.

I wasn’t sure how the black grill was going to look but after seeing it all come together I see what you mean.

Put a factory air box on the burb today to remedy a half assed attempt at a cold air intake. Put on a new filter and changed the oil. Used Pennzoil high mileage 5w20 full synthetic and a Fram XG3980 ultra synthetic filter. Also dumped some high mileage sea foam in the fuel tank. She’s a 200k rig and I don’t know the vehicle history so I figured a little TLC wouldn’t hurt her. Anyone have any experience with these products?

Looking better already! Keep up the great progress.

Digging through RPO codes looking for some specs on the burb. Ran into an unclear area. Anyone know the difference between a MD8 and a M30 code 4L60e?

Welcome back! Already looking good.

The TH700R4 was renamed "4L60" (RPO MD8) following the new General Motors naming convention when the electronic version, 4L60E (RPO M30), was phased in as the 4L60 was being phased out.

So basically it’s the same trans but one is mechanical and one is electronic? Tbh I was hoping for an 80 but I figure it was utilized in 2500/3500. I think I’ll pull the 60 from the Yukon and send it out for a beefier rebuild.
