Can someone help. I'm guessing its something to do with the tranny, but any insight would be great. Thanks in advance!

I'm pretty sure it means that there is some sort of transmission issue, which is why it is a good idea to make sure the on ein there works, but I have no idea what it actually means.

Tranny flush??

The d4 light is like a check engine light for the transmission. Have the code pulled off of the tcu.

Found that is was the speed sensor. $300 to fix... this sux!

that does suck. :/ but at least it wasn't the tranny itself.

I was going to say VSS. $300 to fix sounds a little steep though. You shoudl be able to replace the sensor yourslef. I'm not sure where it is on the TL but I think its held on by 2 10mm bolts and thats it. Check into it befoire you pay someone else 300 bucks to replace the thing. GOod luck.

so I guess that would be a good reason to replace that D4 light :dog:
