New 2006 Tahoe Owner

I meant 3.23 gears. I have the RPO sticker still. GU5, G80, Z82.

1st, those two are contradictory, as the tow package gears were 3.73 & 4.10 ...
2nd, can't presently afford 4.10, but I can barely tolerate 3.73 ...
3rd, forced to choose between 4.10 & a 3rd front seat, I'll take the latter. Getting old, I guess ...

See my RPOs above. As noted in the original post, I've also got a '78 Suburban. Once that's going again, it's got the towing capacity to pull around anything I might need that the Tahoe can't.

Can barely tolerate 3.73, very strongly recommend 4.10.
If you drive assertively on the highway, highway MpG might go down - than again it might not 'cause it won't need to downshift to 3rd or 2nd as often.
Stop'n'go & city & towing MpG will improve, and the 4L60E will last longer between rebuilds.

I've got 4.10s in the race car, 3.73s in the Burb. I have no issues with shifting with the 3.23s. Perfect for my needs. Hauling the family around and a 4x8 HF trailer for our camping gear. The only time the 3.23s may be an issue is when I tow the race car to Tucson in October. But by the next year's race, the Suburban should be going again.

Nice find!
Heading out to Duct Tape Drags?
