The subject of this post basically sums up my problem: My 98 VW Jetta GL's manual transmission won't shift into reverse or fifth gear. I have no problem shifting into first, second, third and fourth gear; but it's absolutely no dice on reverse and fifth. I got a quote from a transmission specialist that it owuld be around $500 just to get the transmission out to diagnose the problem. I found a used transmission with high mileage at a local salvage yard for $550. I really just don't know what to do! Could their be something simple or small causing the transmission to not function properly? Should I try and have it looked at somewhere else, or should I just go for a new transmission? Is it wise to buy a high-mileage used transmission, or is it worth it to put a newer one in there? I found some used ones cheaper on ebay, but that seems risky. Any experience there? I am a layman when it comes to automobiles, so I don't even know where to start. I put $1000 over a year ago into the car, and want to keep it running, I just don't know if it's worth putting another grand or so into. Please use your expertise and know-how to help me figure out what could be wrong, and what step to take next. Thanks!
