chevy 1/2 ton pullers

just put the Sonnax 1-2 and 3-4 shift servos in my 01 Tahoe, and now the 4l60e has tight shift. I haven't pulled with it yet, but it's gotta help. if you into mods on your 1/2 ton, do this one!

My computer mod tighten my shifts. But when I need my tranny rebuilt was going to do that. It only has 165000 on it and still pulling strong. Thanks for the brand info ...
