Start by checking both battery cables on both ends. We've seen a lot of cars with corrosion. this lets enough threw to run lights and stuff, but not enough to turn over the starter.

I did n nothing it still not starting

I have a tranny leak would that mess anything up with the starter

If the tranny fluid is getting on the starter, ya, but you said you put a new starter on and there was no change. If you jump the car, will it crank?

No it won't n yea with the new starter still nothing ....

I would check the battery cables, test them. I've seen several corrode inside the boot

If the battery cables test okay...then I would suggest installing a new starter solenoid.

Is there instructions on a starter seloniod n how do you check the cables
