    Long story short I'm in need of a transmission. I have found a a new in the box that's been sitting for 2 years. It goes to a 07 Chevrolet Avalanche 2x4. And my truck is a 04 Chevy Silverado 4x4. Below are some images of the new transmission and the green tag off of my old transmission. Will it work
  2. Introduction
    I’ve been searching everywhere (monster trans, PerformaBuilt, eBay, etc) and I can’t find a decent transmission for my truck. It went out when I took it to the shop for a suspension upgrade and they took it out and I guess they we’re to rough on it. Which I knew it was on borrowed time as the...

    I reached out to sonnax about how gen 5 LT equipped vehicles shift so well and they told me that the way they do it is by cutting fuel in between the shifts to mimic lifting off of the clutch to shift gears and results of that is smoother and crisper shifts and that sexy shift sound, is it...

    Has anyone ever used a gear vendors here? looking to get some very short gears like 5.13's or 4.88's to use with a 4l60 and then have the gear vendors to be able to cruise nicely on the highway, I'm also wondering about the gear splitting if its worth it for that as well or if its just a gimmick

    Hey guys I’m looking at replacing my transmission in my 1997 GMC Sierra 1500 Z71. I found a fairly new GM crate transmission 4L60E out of a 2004 GMC Suburban Z71 local to me. Would I be able to make that trans work in my 97’ or is there too much difference in the newer 4L60E’s? Thanks!

    I bought this 15 yukon denali with 39000 miles about 3 years ago. My wife daily drives it pretty easy. It starts shifting clunky it seems every 6-8 months and goes to the dealer. 4 of the 5 times the dealer says it need the software updated which lasts for awhile bit time before last a...

    Hi I'm new to the forum but I figured I would post to maybe get some insight or helpful tips. I have a 93 chevrolet blazer 2 door full size 4x4 with 180k miles that I just bought a month ago. When I bought it the guy said he replaced the tranny with one from a 93 suburban so I figured it was...

    I have a 2004 silverado 2500 6.0 with a 4l60e trans. When I am doing 80 on the freeway, it runs at 3000 rpm. Does this sound right? The shop that had just rebuilt my trans had said that my p0300 (random misfire) code is keeping my torque converter from locking up. Does this sound right?
