I have an engine code PO332 knock sensor 2 circuit low imput bank 2 what is this problem .the car is a 2001 gmc yukon xl .


The most likely cause of your code is a bad rear knock sensor. You should check the knock sensor wiring harness for corrosion. But if that checks out the sensor will have to be replaced. The knock sensor is under the intake manifold, although it's not too difficult to remove. Both knock sensors should be replaced along with the wiring harness, just because of labor involved in gaining access to the sensors. You could try clearing the code, it may stay off for a long time.

Why wont my 2001 gmc sierra 2500hd go into 4th gear?


There is a speed/shift sensor you could change, but if you haven't changed the fuel filter in a while, i'd go there first. Sometimes, in fact, often, plugged fuel filters can cause the engine to starve for fuel, and make it seem like the transmission is the problem.

Performance Chips, do they work?


Not on this engine. Timing and fuel are already optimized right up to the point of detonation and then trimmed with the knock sensor. Only hardware will help here and it's really not worth the result.
