Make/Model: Transmission GM 4L60E Auto
Vehicle: 2000 Pontiac WS6 Trans-Am
Just purchased this one. The guy I bought it from took it in on trade, had no idea any of the history on the vehicle. Have AT & coolant samples back, sending off oil and rear diff next week. AT fluid is being flushed tomorrow and filled with Amsoil ATF.

Blackstone Comments:
As far as wear metals are concerned, just iron was readin high in this sample. Averages for the GM 4L60E transmission are based on oil run about 20K miles, so the iron may be from a longer oil run. This would be a normal reading for a fill that's been in place about 40K miles. A long run will also allow insoluble material to accumulate from oil oxidation, and that may be what we are seeing here. The viscosity was thick for an ATF, and oxidation can also cause that. If you decide to buy the car, we suggest doing an oil change for the transmission soon. Not bad, overall.
