Unfortunately for me my 2005 LR3 transmission must be replaced. I would like to buy a re-manufactured by ZF transmission with the "new" valve body (included in the price). That seems to be the best option since it would be new parts. Most transmission shops want to do their own re-build not install an after market transmission purchased separately. Would my general auto service provider be able to do the install of the re-manufactured trans. or is it so complex I need to use a transmission service only? Thank you.
