Here is a list of the different T10's.
I believe our cars had the "Y" code not the "CC" code.
I split mine like an egg in my driveway trying to piss off my neighbor. That was a $1500 burnout. I bought a brand new T10 "S" code. the car was a dog off the line. Later on I did a Keisler 5 speed conversion. Much better than the T10.
My engine was only putting out 340-350hp with 380 ft.lbs. torque.
