Unfortunately the only thing you can do to get your VW Jetta to pass the
smog inspection is the get rid of the TCC P0740 trouble code; and that's by
fixing the transmission. I can only recommend you shop around for the best
price to fix your VW's transmission problem. Depending on the overall
condition of the transmission, you may not necessarily need an entire
transmission rebuild or a new one. A transmission shop may be able to fix
only the torque converter clutch portion of your Jetta's trans.
