This is all that's left of a defective 4L60E Automatic Transmission belonging to a 2000 Oldsmobile Bravada. This particular transmission is known for problems with the Reaction Sun Shell -a key internal transmission part. Although Jerry's Auto Repair doesn't have "Transmission Repair" as a part of our name we perform dozens of Automatic Transmission Repairs as a part of our regular workflow. We are able to test and solve electronic problems with transmissions and when the transmission has a serious internal failure (like this 4L60E) we are able to install a new reliable transmission with a 3 Year / 50,000 mile warranty. -Jerry
