check all the fuses before you do anything else. After all a fuse provides power to the electronic box that controls the transmission. Other than that I would not advice on a more complicated troubleshooting since there is no way for you to test a bad transmission computer, even mechanic shops don't know how to test them. The only thing they would do is slap a known good one and see what happens.

SOURCE: P0700 code?
P0700 is a code that tells u the TCM [transmission Control Module] has requested that the PCM [Powertrain Control Module] turn on the check engine light, u now need to ge the TCM tested for the transmission fault code(s) that were stored when the check engine light was turned on by the TCM through and by the PCM

p0700 is pretty much the generic code for saying the computer that controls your transmission has a problem, it may not be the actual computer its self, but one of its sensores, or a bad wire, i would recomend taking it to a reputable transmission shop

P1130: Most likely you have a bad oxygen sensor. This would be the first oxygen sensor if you have more than one meaning the one closest to the engine and BEFORE the catalytic converter. They're pretty common and inexpensive enough where I'd recommend changing that first and see if the light goes out on it's own.Hope this helps Tim

The vehicle until warm runs off a different set of
parameters for the computer as far as timing and fuel are concerned.
Temp is not a problem at 200... and it is normal for the oil pressure
to lower once warm. ( as long as you have 10 psi oil pressure for
every 1,000 rpm's you are ok.)
The two codes cam/crank sensor are timing related related. So I would suspect something that deals with both sensors,Timing chain maybe?This particular engine has a problem with chewing up timing chains. If you find this to be the problem i recommend using factory GM replacement parts. I have had to re-do several that i tried to use aftermarket parts on. The only other thing that comes to mind , dealing with the drive ability, is the fuel pressure. These vehicles are sensitive in the fuel pressure area, but this should not make the light on the dash come on. You may have more than one issue. The other part of the vehicle that deals with timing is the ECM. If you have access to a scan tool with data stream on it , you can look and see if the ECM is receiving a signal.
