    603025 is rated 2.8 out of 5 by 32.
    Rated 5 out of 5 by from 10,000 miles in, so far its great Works great with my 4x4 Sierra stock engine running 35s. Climbs hills with ease and also feels much more stable than stock doing 75-80 on roadtrips. Compared to stock trans, you can feel the shifts are a lot more firm. Highly recommend an upgraded trans cooler to keep your 4l60e/4l65e alive.

    Rated 5 out of 5 by from Powerful Took a trip from Virginia to Michigan, it was night and day. Lower rpm than factory. Plus I could really see the benefits of my engine upgrades done previously with this transmission. Had to remember that I wasn't in a race car lol. Told my avalanche group all about it
