It's my only running vehicle and I'm single on fixed income SS, with 4 kids and 2 are disabled. I'm despirate to get this fixed. What do I do?
Check the wiriung connector on the input and output sensors, the output sensor may also be defective. Here is a link to show where these sensors are on the transmission:
