Those big name brands that use bad, cheap, worn, or damaged parts OR don’t include all the upgrade parts listed in their build sheets. Many would be mortified if they saw some of the sub-standard work we see come through our shop. It’s very obvious when we get inside units built by others that most don’t possess these fundamentals.Īnother reason the 4L60E has a bad reputation is due to unscrupulous “builders”. This requires knowledge of lube circuits, apply circuits, apply-rate, accumulation, clamping force, apply-pressure, hard parts strength, and clutch, band, and steel material. In sharp contrast to many “builders”, I actually have a comprehensive understanding of how they work. I’ve been working with the 4L60E very closely since they came out in 1993. You’re not going to be flipping burgers one day, and get a job at a big transmission conglomerate and call yourself an “expert” in 2 days because you manage to assemble the parts in the correct order. ![]() It’s also not a transmission that you can just go in a parts catalog and order everything marked “Performance”, and expect it to work and/or last. This isn’t a transmission you’re going to build correctly, using an ATSG assembly manual or a YouTube video. There are too many “builders” out there who are promising things that are above their grade levels. The BIGGEST problem with the 4L60E is the huge lack of knowledge and qualified builders. How can we do this, while many claim these transmissions won’t hold up in a typical 300 horsepower application? While the stock 4L60E has numerous design flaws and weak areas, they can all be corrected. We currently have our Ultra Pro Race builds eclipsing 1200 horsepower in C5 Corvettes.

The 4L60s use an input shaft that is 298mm while the 4L65 (and 4L70) series uses a 300mm input shaft as well as converters developed for LS applications only. Both units also have input shafts and torque convert that vary from one another. The primary difference between the 4L60E and the 4L65E is that the former uses a 6.5" depth bell housing while the latter a 7\" depth bell housing.
