Just got a 97 Jetta Sedan 2.0L I4 EFI about a month ago. It's been sitting for a year-hardly ever driven, so I knew it would have problems. After putting in about $500 to bring it up to maintenance, The transmission has since been slipping progressively worse. Went to get the fluids flushed, filter replaced, and transmission serviced, and it's running a little better in low gears (was slipping in low gears to make it jerk real hard), so now it just does it a little in the high gears...Mechanic told me it probably needs a valve body- $1400. If I pay that amount of money, will it just go out again? Having trouble finding answers online...Are Jettas notorious for transmission problems, or do y'all think it's just from sitting for a yr? Plus, it's going to need $500 or so more work done...and it's staring to show signs of electrical issues...How long do you think I have before this car breaks down on me?
