HAVE MORE FAITH IN REPAIR SHOPS, EVERYONE IS NOT OUT TO RIP YOU OFF! THIS IS A TRANS CODE I THINK
JUST SITTING HERE KILLING TIME DON'T HAVE ANY DATA. WHAT IS THE VAN DOING.
YOU CAN ALWAYS GET A SECOND AND THIRD OPINION AND ESTIMATE!
get a 2nd opinion from a good shop and believe what they say unless they don't fix your car
