I'd be more worried about the trans then the motor.
IIRC dbtk2 had over 200k on his L36 gpgt.

I agree, you don't have much to worry about with the motor. But the trans will be due sometime. L67'* are more brutal on the 4T60, but have a good feeling about it. The 60 can be BUILT.

Mike, you got Email.

yea i just did a tranny service...the first one (oops) but it was still good tho except for the fact that the tranny fluid was as black as oil, but the magnet wasnt covered in shavings and i broke open the filter and there was nothing out of the ordinary...after i did that the car shifts better and rides nicer...but i was just thinkin worse case scenario
