Urgent Help
 

I have 3 question!!!!
Is the TCM the ECM/PCM?
Where is the TCM?
and what is especially P0700 and how can i fix it?

P0700 is a general trans code, thrown by the PCM when the TCM side has a code in it for the trans. A P0700 code normally indicates there are more transmission codes stored. You would not expect to see a P0700 by itself.

Most folks end up replacing the whole trans with a rebuilt one when they get this code at dealerships but you can take it apart and try to rebuild it but you'll probably run into more problems. Try to get a shop with Honda Diagnostic System (HDS) to pull out the transmission codes or see if there are any other errors.

You should also notice the D light in the gauge cluster blinking!

Yes D is blinking!

I have change the transmission! I think it is a old code or electronic?
The other Code is P2270 but this is the Oxygen Sensor!
Also is the TCM the PCM? Or is it two different things?
When I change the PCM can I Fix it?

If you changed the transmission and are getting the code you should first try to clear all the codes Via Honda Diagnostic System (HDS) and see if it comes back on.

If it comes back on there is a problem with the new transmission or your PCM/TCM. As far as I know, the TCM/PCM are 1 unit, however one harness on it controls the Transmission while the other controls the engine and so on.
