2002 trailblazer LTZ Transmission
 

I just recently bought this vehicle fully loaded. Found out that this model and year has bad transmission problems. My wife has notified me of light indicater for 4wd either 2wd is flickering on and off. Do have to worry about this. Also body parts for spare tire brace bar has rusted out and its hanging low, I don't want to lose this down the road. Plus I tried to lower it down and it won't do anything. Do I need to cut one out of wreck vehicle so it can or can this part be ordered. Help, thanks Tno657...
