I just recently bought a 2000 Oldsmobile Intrigue 3.5L V6 with an automatic tranny for dirt cheap but it had a check engine light on. I ran the scan tool and came up with 6 codes. I just want to know if any of the codes are related. Theres 1 code that gets me nervous too. Here's the codes, P0131, P0137, P0385, P0440, P0730, and P1372. The code that gets me nervous is the P0730 because its a transmission code for Incorrect Gear Ratio. The car does run rough and stumbles but I can't tell if thats the tranny causing it or the bad crankshaft position sensor. The car also needs a new battery. Not sure if that is related to any of these codes. Thanks in advance.

Why would a Crank sensor give you a trans code? Incorrect gear ratio means the transmission is slipping. The input and output speed sensor are not reading correct speeds for the gear you are in.
The P0385 refers to a Cranks sensor issue but not related to the trans issue. This has 2 Crank sensors and there is a problem with one of them or the related wiring.

I wasn't sure since the crank sensor monitors the RPMs, maybe the shift points would be messing up or something along those lines. Is there a way to find out which crank sensor it is? And any input on any of the other codes?

It appears they have combined 2 sensors into one housing so there is only one sensor. You need to resolve some of these issues before tackling the other codes.
