Replace either the cables, the posts, or the battery, or all of the above :) ..... You can alsu try using a post cleaner, i guess the first step is to see where the connection is loose, if its the battery terminals then replace them first

2001 jetta automatic transmission does not down shift or shift into overdrive


Once again, not enough information given. How many miles on unit? When you say does not downshift do you mean when you press hard on accelerator pedal, or when you slow down? When you say does not shift into overdrive do you mean high gear or torque converter does not lock? The cars are know for transmission problems and while sometimes you get lucky, usually they require a rebuild or replacement. How often do you replace the fluid and filter?

Check & replace if necessary the brake pedal switch placed above pedals on the support.
If the problem still occurs you might access the Engine Control Module (ECM) using suitable diagnostic equipment connected to the data link connector of the car, in order to pull out all DTC (Diagnostic Trouble Codes) memored. Then you will be able to replace bad piece(s) and fix the problem by erasing all DTC's stocked inside ECM & reset it.

Yahoo.com.mxDiagnostic trouble codes reported: P0740 and P0420, The Catalyst was replaced one year ago. Thanks


PO740 -- trans torque converter clutch

PO420 - converter as you said.

Do you have 2 or a bad O2 Monitor Sensor

If a converter goes bad in less than 12 years
or more ,you have to fix the reason it failed,
not just install a new one

My epc light went on in my 2002 volkswagen jetta


Take it to the dealer, the EPC warning light - and even more the failsafe run which doesn't allow you drive faster than 20mph) is an indication of serious motor troubles. They can read the ECU faultcodes, which should be a good startingpoint for troubleshooting the cause ...

You could do some basic troubleshooting like checking the air filter, the oil level, the spark plugs, etc. You didn't fill it up with bad gas, did you ? And does the engine make strange noises/vibration when running idle ? In case you fixed some obvious cause, you can dis- and reconnect the battery to erase the engine's faultcode. If it's not fixed, the EPC (and failsafe run) will simply come on again.

My advice would be not to drive it untill it's fixed to prevent more potential damage.
