I have a 94 LT1. The other morning (sat.) go to start the car put it in OD stayed in 3rd the entire time! Checked the fluid looked a little low put a half a qt in was running perfectly all weekend. Mon. morning go to work same scenario? Was told to pull the pan, drain and change the filter. Left work and drove beautifully! Tue. morning same thing stopped at a light after drivin for like 5 min. turned the car off for 10 sec. and started it back up and drove beautifully! Now I realize its electrical most likely does anyone have any suggestions on what it could be? Im gonna scan it tomorrow to see if its throwin codes.

 

i have a 95 z28 that i just got, doing the same thing. please post the answer if you figure it out and i will do the same. thanks
