Have all gears except reverse, what could be the problem? I can drive my car foward but when I go to back up in reverse I have no reverse. What could the problem be? Please help! I tried taking out the shift solenoid, but that doesn't work, does anyone know how this could be happening.

There isn't much you're going to do yourself with this. The first thing your mechanic will do is connect a scanner to see if there's any diagnostic fault codes related to this problem. Next, it will show if any shift solenoids are being activated by the computer. A pressure test may be needed to see what is happening in reverse. If the reverse servo is getting pressurized but there's still no reverse, suspect a broken band. Replacing that is very involved. On older transmissions that were hydraulically-controlled, the clue was when you drive in "low" or "1", it would still up-shift to second gear. I don't know if that is still a valid test with electronically-controlled transmissions.
