Limp it home if you have to, but get it diagnosed immediately. Transmission damage gets expensive fast.

What P0700 Means

P0700 is a generic notice from the transmission control module that something is wrong, but it does not tell you what. There will always be a more specific code stored alongside it.

Common Causes

Internal transmission fault
Failed solenoid pack
Wiring problems to transmission sensors
Low or burnt transmission fluid — see repair cost

Diagnostic Tips

Always get the secondary transmission codes (P07xx series) read along with P0700.
Check fluid level and condition first, it is the cheapest diagnostic.
Avoid hard acceleration until repaired.
