If an early '99 Jetta may be bad Valve body or harness for A/T--again
must check codes including transmission codes. If transmission codes
are hard codes-won't clear and you want to try to fix yourself, we
could point you toward an excellent book our store, www.SelectEuroCars.com
uses to test these. Unfortunately then, when the repair is done,
trans fluid must be refilled to proper level and that should be done
with VAG-Com, a factory computer or the equivalent.
