I think your transmission has failed internally. Very sorry to tell you it sounds bad.
Ask a VW specialist or a transmission shop and get a diagnosis and estimate of the price to fix it.

thanks a lot for your care & answer yes as you said it was bad & it went worse i just changed the whole gear box with a new one 2004 but after they fix it the gear goes only reverse & 1st shift only they talking about gear sensor or somthing in car wiering is that true or what ???
update i think the car went into limpmode the TCM needs to be programed thats what the VW dealer told me ???
reverse light switch is causing all you promlems $20 from vw
