i'm hearing a grinding noise that is very brief when i shift from first to second and it's only when i run the car hard. under normal conditions it shifts great also no noise through any other shifts the trans is a t-5 in my 86 lx 5.0 the trans has all new synchros and new gears i bought it with a broken shift fork and had it rebuilt. i have been to the track several times now and have had no problems but i'm not sure if the noise is something to be concerned with also was wondering about clutch adjustment it grabs about 3" from the floor. one more thing it seems to happen more when the eng/trans is cold.
