Honda Repair: Coincidence?, transmission drivetrain, suspension component

Question
A week ago, I had my mechanic install bushings on the front tires of my 98 Honda Accord(120K miles on it). When I drove it again a couple of days later,it sounded worse.  Took it back to the mechanic who stated that his worker installed the left sided one wrong. After correcting this, the next day the transmission went.  Do you think this is just a coincidence or are the two related? Especially since he installed it incorrectly the first time.  Thanks for your help!

Answer
Kevin, doubtful. 120K on your car the transmissions generally go out around this time. Bushings? On the front tires? I dont know what service you were getting. Possibly bearings? Bushings = suspension system. Bearings = drivetrain. Transmission = drivetrain. If he installed a drivetrain component (bearing) then yes it could have been possible that this could have damaged the transmission. If he installed a suspension component then it would be very difficult to damage the transmission.
