cant figuire whats wrong with my 1994 expo.engine starts and idles but wont go. wont back up or anything.i heard it could be a tourque converter. do you know where this is located? i have a cell phone number u can text me its 985-590-8107. thanks

either torque converter, front pump failure or low fluid level. it may have to come out and be overhauled.
