I paid $1300.00 to have my ZF re-built. It looked new when I picked it up, unfortunately it works exactly the same as it did prior to the "re-build". Extremely displeased with the product I received and their non existent customer service. Supposed to have a one year "no questions" asked warranty. What I didn't realize was this meant they wanted your money and you weren't supposed to ask any questions! My advice is to carefully select a rebuilder, and completely understand their warranty prior to spending your hard earned money. For example, ask about removal and installation labor costs, towing charges, & rental car fees in the event their re-built transmission needs to be removed. They may also require you purchasing other new components (clutch disc, throw-out bearing, etc.) to activate warranty....
