To start with "P" codes from the engine computer aren't that exact on what is happening with the transmission.

You need to read codes from the trans controller! THERE are 96 codes possible & another 96 intermittant codes!

ALSO P0 730 means that the trans is slipping!
Again a scanner that can read live data from the trans controller will show if the trans clutches can still lock-up.

P0 700 or P0 715 can mean that the RPM sensors have a problem, but can also signal MANY other problems as well!
