I was just searching the threads again and I can't seem to find what I'm looking for. It's not a big deal but just wanted to know if I have a chance to repair this little issue. Anyway, when I first bought the 91 300E with 172K, it started making a "clackity-clack" sound when I backed up using power. I panicked and took it to an expert "independent" MB repair shop. The tech drove it around and told me I needed a new transmission ($3,500). I sighed and left figuring I'd just drive it until it died. Also, when I go from park to drive or reverse, it delays and then jumps a little (lunges). No big deal. Hasn't worsened or improved. Shifting is still great and firm. I have 186K on it now. The reverse sound isn't there anymore. It still has the delay and I was wondering what that is caused by and if someone could fix vs. replacing the whole tranny. I want to go back to that guy and slam him. Also, another guy told me I needed a new water pump ($800.00 labor + pump I was quoted) when he saw my fan clutch wobbling. Thanks to this website, I replced the fan and clutch...no problems since!!!
