    Rated 2 out of 5 by from Wouldn't recommend Got this to replace the 4l60 I blew in my Silverado. It arrived poorly packaged (it poked through the flimsy box it was packaged in), but I figured whatever, it didn't have any damage. Im happy it comes fully assembled with electronics and all, it made install smooth, paired the trans with a new oem torque converter. Started it up and it ran great until it hit the highway. After that it got a p1870 code. I plan to replace the valve body since I have a new fully assembled one in my garage. Hopefully that does the trick. Ive also noticed trans fluid seeping slowly out of the bellhousing access hole/dust cover. Should have bought a rebuild kit and rebuilt my existing 4l60, overall disappointed with this product for apparently being dyno tested and built to last. They should also package this MUCH better. The box it came in was a joke. Price is pretty average, but should reflect a product that won't have problems out of the box. Time to sort out this p1870...

    Rated 2 out of 5 by from Shift solenoid a I really hate writing bad reviews. But I bought this 4L60E in Hopes to have my GTO back but now after installing. Trying to figure out what's going on with shift solenoid a for a P0753 code "shift solenoid a electrical" pretty bummed after installing to find out my car would still be on jack stands. Packaging was great and transmission looked great on the outside but its stuck in limp mode for now..
