my car through these codes today at the red light are they serious codes:
P0755 P0758 help? what are they?

I believe both are tranny related, I wasn't able to find the exact definition of po758, but po755 brought up tranny solenoid b malfunction. The only reference books I have are chevy and obd1 ford. This info was taken off the net. Hope this helps.
