2003 G35 auto sedan. I was wondering if anyone has experienced any problems where the car goes into a limp mode. It wont shift. I just got the transmission replaced with a used transmission, because the dealer said it was the valve body. Codes didn't clear after the replaced transmission was installed. Any suggestion? What was the actually problem when it was going into limp mode from the beginning? Could it be wiring or a sensor? Ive spent $2700 and i still don't know the problem. Help!!!!!

 

why wouldnt they just replace the VB?

 

No warranty plus vb was the same price as the transmission and they thought the transmission could have been damaged.

 

hahah well your own little mistake for taking a used transmission. if it wasnt shifting, anyone knows the first place to look on an auto is the VB....

 

so your saying i bought another transmission with the same problem????

 

no, im saying that you replaced a perfectly good transmission.

your valve body is most likely the problem. i suggest you request that your dealer change it, as they are stupid not to diagnose the problem correctly.

 

Is the valve body an internal part on the transmission? Sorry for the basic question.I have the feeling its not

 

if you drain the tranny fluid, take off the tranny pan, its RIGHT there.

cant miss it.

big ugly peice of **** that my car HATES>

 

So would i not get a working one with a different transmission or is it not even a part of the transmission?

 

i would call tomorrow and see if you have your origional or a new one..

i have no idea what they did, but from what you posted and from what i understand, you still have the bad VB if it even is the VB.

 

with the replaced transmission would i not get a different vb with that?

 

ill call tomorrow. Thanks for your help.
