my th350 has a leak from the converter cover and recently it won't shift out of 2nd (when you put it in drive). I'm assuming the leak is a torque converter seal? Can the torque converter also be the problem with shifting? I haven't checked the vacuum line to the th350 yet and will be looking at this closer tomorrow. Took it to the corner gas station and it was running fine going there, coming home it wouldn't shift thru the gears. Any advice from you all would be appreciated.
