Hi All, I know there are lots of posts about these 2 codes. But thought I would take a stab at a post. We have a 2001 LX and has 101,000 miles on it. It's never had a single mechanical issue in 11 years!
The other day the TCS light came on and the CEL came on - TCS went out but CEL stayedl on - got these 2 codes at AutoZone
P1738 and P0740
I popped the hood and checked my tranny fluid levels and it's perfect - but noticed I had some corrosion on the battery terminal - so I took that off and cleaned it up. Now the light went out but occasionally it still shifts bad 1st-2nd
I ALSO notice that the car idles about 650-700 rpms - it used to be like 800-900 before. I also notice that when I take my foot of the gas the rpms will dip below 1000 when driving. so I wonder if i could have a electrical issue.
basically I just looking for the cheapest way to diagnose this puppy, don't have a ton of cash.
