Parts cleaned using industrial parts washers and Aluma Blast coating. Exceptionally clean units is one of the reasons why our transmissions are the highest quality in the business! We have state-of-the-art cleaning equipment which other trans builders could only dream of. More info HERE
With the best cleaning equipment, we also have a very clean facility. All units are built in a spotless environment and using tools, and benches, which are clean and only used for assembly purposes. In other words, the same tools used to pull your dirty old trans out of your car are NOT the same tools used to rebuild your pristine unit afterward. Take a look at the typical shop and check their tools. It is shocking how dirty things are in most shops and that dirt will end up in your unit. That doesn't happen here.
Your unit is also shipped in a double walled custom made box for Jacks Transmissions. Your unit will be sitting snugly, and safely, in preformed foam pads to assure trouble free delivery.
Note: Core charges will be refunded -- depending on the condition of your core!!
CORE RETURNS MUST BE RECEIVED WITHIN 60 DAYS FROM THE ORIGINAL ORDER DATE
