What it means, what causes it, and what it costs to fix.
What P0700 means
P0700 is a flag, not the problem itself. It means the transmission computer has stored its own code. A basic code reader often can't see that code, so you need a scan tool that reads the transmission module.
Can I drive with P0700?
Severity: Medium. Fix soon so it doesn't turn into something bigger.
Depends on how it shifts. Many cars go into limp mode, stuck in one gear. Drive gently and get it scanned with a tool that reads transmission codes.
