Day's Transmission Repair

I HAD TRANSMISSION WORK DONE ON MY COBALT ALMOST 2 YRS AGO AT DAY TRANSMISSION REPAIR. MY CAR IS CURRENTLY BACK IN A SHOP(NOT THE SAME ONE OF COURSE) AND HAS BEEN FOR 2WKS NOW. THE MECHANIC WORKING ON IT IS VERY EDUCATED IN TRANSMISSION REPAIR/REBUILD. AND HE IS ABSOLUTELY BAFFLED AT WHAT HE HAS FOUND. WHILE AT DAY REPAIR THE SHIFT CYLINOIDS WERE REPLACED...VERY SIMPLE WORK FROM WHAT I UNDERSTAND, HOWEVER HIS MECHANICS MANAGED TO PUT PARTS IN BACKWARDS WHILE PUTTING IT BACK TOGETHER. I DIDN'T EVEN REALIZE THIS WAS POSSIBLE! BUT I GUESS A SHADY MECHANIC CAN MAKE ANYTHING POSSIBLE.
MY CARS ELECTRICAL SYSTEM IS ALL OVER THE PLACE AND THE FELLA WORKING ON IT LIKE I SAID IS BAFFLED, AS HE HAS NEVER SEEN SUCH THINGS IN HIS 30+ YEARS OF DOING THIS TYPE OF WORK. NEEDLESS TO SAY...I WOULD NOT RECOMMEND ANYONE TAKE THEIR VEHICLE TO DAY TRANSMISSION REPAIR. THANK YOU FOR TAKING THE TIME TO READ, YOU WILL BE GLAD YOU DID.
