Transmission won t engage, check engine light on

well the low cost way to go first would be to try and change the trans fluids. If the problems still remains the it may be an internal problem

I was told to change my Transmission Control Module,located on the transmission . You can get it new for under $200 but, I was advised to get it from a junk yard it's alot cheaper and its easier. I hope this helps

SOURCE: LS430 check VSC light on after check engine light on

My car (06 GS430) began giving me more frequent "Check VSC" warnings. (Code P0455 in my case. Really glad I bought that OBDII tool--resetting the codes is a snap!)

I knew that a loose gas cap could cause this, so normally I just give it a twist and it tightens. Now I found that no matter how many "clicks" I tightened the gas cap, it would not cinch down snug. The lightest turn the opposite way would open it.

I was all set to head over to CarQuest for a replacement filler cap. But I thought I'd inspect mine first just to see why it stopped holding. Upon inspection, I saw that what holds the cap in place is compression of the rubber O-ring at the back of the cap, which compresses against the filler neck. That apparently was no longer happening.

I carefully removed the O-ring from the cap--using screwdrivers to lift it over the edge of the groove it sits in. Like removing a bike tire from the rim--work your way around. Then I cut a strip of electrical tape about 10" long, and 1/4" wide. I wound this into the curved groove where the O-ring normally sits, just to build up a little thickness. Put the O-ring back in place. Done.

Now the cap tightens like it's supposed to, and thus far, it has stopped the VSC error codes. Don't know if it will fix your issue or not, Good luck.

your pump inside the transmission might be bad or governor isnt wronging right..but its all about the tranny here...

SOURCE: Transmission or Engagement issue?

I had the same problem with my 2006 Forenza - the problem was the transmission range sensor. If you look under the hood, on the drivers side, you'll see your trans. cable connected to a round part that also has an electrical cable coming from it. That is it. Part costs $36.07 at oemsuzukiparts.com (search for Neutral safety switch in the mechanical catalog).
