How can I make her reliable again without breaking what bank I have. Whats wrong

Hello, first - the shift solenoid issue is more than likely an internal transmission. mechanical issue. Changing a solenoid will not likely be a sustainable repair. You should be thinking that the transmission itself is likely in question. Second, you can't continue to drive the vehicle if there is a known issue. It's likely to make things worse. I appreciate that it's your only vehicle, but - what now? You've had to figure out an alternative. If you stopped earlier to repair the vehicle it might not have worsened to this point. Third, You said the alternator is bad, then the alternator is good. Have you had the starting and charging system tested? Starting with the battery, does it sustain a full charge and handle a load? Are you certain the "stalling" issue is due to a charging system concern? You mentioned that the alternator is "good". When you turn the key, is it totally dead? www.repairpal.com/repair-shops That's a link to find a shop near you -- which ultimately would serve you better than the guessing that's been done to this point.
