Thread: bad torque converter?

  1. #1

    bad torque converter?

    Would shifting issues from 1-2 be caused by a bad torque converter? Does it primarily at low rpms. Tranny fluid smells a little burnt, but no metal and no extra noise that I can tell.

    TC is involved in all transmission actions/gears/stuff. An issue with one gear or one shift is something else.

    You could have a servo seal or piston problem, 2-4 band burnt, reverse input drum failed (by the 2-4 band usually), 1-2 accumulator cracked, valve body problem, low line pressure...the list goes on.

    I only needed the rear output shaft changed for 2wd to 4wd and the A hole rebuilt the whole tranny. I will just replace it. Anyone need a 4l80e that needs a little work?? Supposedly only 30k miles on it and was real clean...still is.

    sounds like a good time to build a solid horsepower rated tranny..
