As you turn to merge onto the freeway, your car makes a "thud" sound and you feel the resistance as the tranny resists the gearshift. This isn?t the first time that your noticed a transmission problem and you know that these repairs are likely to be. Although you believe that car parts aren?t as sturdy as they once were, you might be surprised to discover that the tranny in your car isn?t all that different from the original ones that came off the line in the 1930s and 40s. The fact that people drive more makes it seem like their American made Ford or Chevy transmissions aren?t as good as they once were. Think about how much you use your car on a daily basis, how much time it spends cruising at high speeds and shifting from gear to gear. All of this causes wear and tear, often resulting in problems. The good thing is that the reliable sellers on eBay have a variety of new and rebuilt transmissions in stock. If you end up needing a full replacement, the options are likely less expensive than you might think. Furthermore, if you act quickly, you are likely to repair the issue with only a replacement part saving time, as well as money.
