My boyfriend drove me to dr. Yesterday at 70mph with my Honda Pilot in 2 nd gear. Did he damage my car?
If there were any real damage, you would know right away. Listen carefully for any unusual whirring sounds, hard shifting, etc. during normal usage.
You might consider having the transmission fluid changed at a shop. Running the transmission at a sustained, high rate could easily overheat and sheer the fluid. Worn fluid will cause damage to internal metal parts before long. A servicing costs about $125 for your vehicle and would be well worth the effort.
