open the glove box theres a sticker with rpo codes, take a pic of it, then search google for 07 tahoe rpo gear codes

Will try that thx

code GU6 is a 3.42 ratio

there are no codes in glove box anyone know the GCWR of o7 yukon with 5.3 no owners manual and have not been able to find on internet thx

owners manuals are on the web for free. the only other way is to search the vin# or ask the dealer to call the gm dealer to run the vin and fax them a rpo list of options it has. as they own it. dealers only give info to the owner, not some guy with a vin walking off the street with no proof of ownership.

You can go to the GM site and start a chat support, give them the VIN and they should copy and paste a build sheet into the chat window.

Jim, go to compnine.com and put in the VIN, costs a couple of bucks. It will give you the RPO sheet and other information about your prospect vehicles. Look up the G-codes for the axle ratio.

There should be a sticker on the driver's door jamb too showing the GVWR of that particular vehicle as optioned.

A 4-speed Yukon, the short one, with a 5.3 had these specs for towing:

2WD with 3.42 Gear: 6,400 lbs
2WD with 3.73 Gear: 7,500 lbs
4WD with 3.73 Gear: 7,200 lbs
4WD with 4.10 Gears: 8,200 lbs

Don't know what you know about trailering, there are many other factors and weights to consider when towing.
