1999 Volkswagen Transmission/Shifting Problems. Advice Please?
My wife has a 1999 Volkswagen Jetta. I think it is the GLX. It has roughly 150,000 miles on it. It has been experiencing shifting problems for a while
now. I didn't realize how bad until I drove it again a few days ago. Then today when she was going to work it wouldn't fully start. It was trying to,
but wouldn't. I ended up taking her to work on my way back to work. I didn't take a look at it then. I am wondering if the transmission could be
preventing it from starting, I read something about the electrical system and emergency modes. I'll try boosting it off when I get home and see if it is simply the battery.
However, to talk actually about the transmission.
She can be stopped at a redlight, and when she begins to accelerate it will first stall for about one second, then it will jolt forward, spinning the tires on the pavement and moving suddenly.
However, if you place it in 1st gear manually while stopped, and then accelerate, it does fine. It also does fine when you manually shift into 2nd gear at around 2500 rpm.
I am worried that the transmission needs replacing/rebuilding. That would probably cost more than what the car is worth. However, since it seems to
shift ok manually (via the "sport shifter), I am clinging to the hope that it will hopefully fix it to simply have the transmission serviced. What is
the likelihoods of this?
As soon as I get home today, I plan on checking to see what transmission specifically the car has. Assuming I get it up and running easily tonight via a
boost of the battery, what sort of troubleshooting, diagnostics can I do to discover more about what is causing it?
I have arrangements to get it to a shop Monday (that is the earliest they can see us). I would like to do everything I can in troubleshooting before
then. I need all the advice I can get, and will provide any further information I can if requested.
Thanks in advance.
