4L80e Transmission Rebuild. A better solution is the 4L80e transmission. This 4 speed automatic is found in the ton and up pickups, and has been around since 1991. It is designed to handle much more engine torque and vehicle weight than the 4L60e, but is also physically heavier than the 60. The 4L80e’s first and second gear ratios are much.

  • Make good decisions even with incomplete information. You will never have all the information you need. What matters is what you do with the information you have.
  • Always trust your intuition, which resembles a hidden supercomputer in the mind. It can help you do the right thing at the right time if you give it a chance.

I've got a couple of 475s and I've had one in my buggy, the gear whine was very noticeable in 1st gear. My wife didn't like the whine and when she built her buggy she didn't want a 475 in hers because we spend a significant amount of time in 1st gear. The 475s that I've gotten came in vehicles that didn't have a park pawl, so I had to add that. Gus.
