Automobile repairs

Right now am living paycheck to paycheck. My tranmission went out in my car and it cost me 3500 dollars to replace. I got to where i can make payments but that going to cost me 600 a month and I cant afford that with rent, insurance and car payment along with my other bills. I would usually not do this but am desperate. So i ask, if you can help i will appreciate it and be thankful that there are good people out there willing to help out a stranger. Thank you..
