Question about 2001 Chevrolet Blazer
If you are smelling gas it is because you are getting excess fuel somewhere
Most likely it is the fuel injection unit or the fuel pressure regulator inside the intake plenium on top of the motor there is a shrader valve on top on drivers side of air intake on the fuel lines have someone pressure test the fuel pressure when you turn the key on and off three or more times to prime the pressure then turn the key off and watch the gauge while priming pressure the pressure should be 60 psi then after priming pressure and turning key off pressure should drop to 55psi and hold that pressure for 5 minutes minimum if it does not hold that pressure and starts dropping to zero your fuel injection unit and pressure regulator are leaking and dumping excess gas into the air intake plenium and it is easier to replace the injection unit and the pressure regulator as you can buy them cheaper combined a new injection unit comes with the new fuel pressure regulator
And if they are leaking gasoline after a failed pressure test that is why you are smelling gasoline
Have it pressure tested right away as if this indeed is the cause the excess fuel could combust at one point and cause a lot more damage
A pressure tester can be purchased at advanced auto for around 35 or any reputable garage can pressure test it in front of you in 5 minutes it's easy

You have a 4L60E whick is controled by your ECM. It sounds like you need and new transmission, the sun gear in it has failed and is the weak point on this transmission.
When you get a new transmission have them to a corvette servo upgrade. The part is only $45.00 and the shop should know about the upgrade. It will make your truck shift a lot more firmer but last longer.

Good luck and hope this helps

In addition to the great answer above, it is extreamly improtant to torque the front hub nut to the proper torque. If you under or over torque the nut which puts pressure on the bearing, you will be changing it again in a very short time. Refer to a shop manual, or go to the local auto parts store and look at a chiltons manual for reference torque value.
