If you have a laptop running windows, you can get a fairly inexpensive scan tool to read live data. I would recommend http://www.amazon.com/ScanTool-423001-ElmScan-Diagnostic-Software/dp/B002PYBZJO/ref=sr_1_5?ie=UTF8&qid=1391118306&sr=8-5&keywords=obd2+usb
You can get cheaper ones, but they are generally not very good, it’s crap shoot with the copies in china. But that one comes with OBDWiz software that will allow you to view a decent about of generic obd2 data. You should be able to use it to view throttle position, and see if that is your issue. You will want to see a smooth increase of throttle position as you step on the accelerator, if you see jumpy readings, you will know your TPS is probably at fault. If not, you will have to dive deeper.
I would recommend looking at fuel trips, great video on that: http://www.youtube.com/watch?v=oRX2V6_a3dc
I second spelunkerd on this one. To properly diagnose this, having a lift is invaluable. Trying to do this on the ground can get sketchy very fast.

Sounds like a good starting point, basic maintenance, but don’t be discouraged if that doesn’t fully fix the issue. Proper diagnosis tools will be required to pinpoint the issue.

That kind of noise from an automatic transmission is never good. They are a beast of their own. Are you sure it is the transmission making the noise? My guess is it might be the differential(s), as you mentioned it was pulling to the left.

Do you have a decent scantool that can read live data? Any Check Engine Light? Trying to diagnose without a good scantool will be next to impossible.

I don’t think that reader can read GM misfire per cyl pid’s, but you can try. Look through the live data PID’s on the tool and see if you can see misfire’s per cyl.

The best way is to get access to a more powerful impact. Even a 3/4 or 1 inch gun if you have to. The impacting motion will be much nicer to the bolts then twisting them with a huge cheater bar. Remember, impact guns generate torque over time, so keep on it for 10-20 seconds.
