Hi, I am new and since June of '07 I am sorting out my 1981 300sd with various issues, one being the trans. Hot outside temps made reverse was slow,up to 3 seconds, and now cooler temps (40-50F) and no delay cold and 1 second hot off the highway at 85c on the dash. Fresh fluid (Dex 3 Cam2) and filter. A fresh new style B2 piston (used) installed. No leaks,all Vacuum corrected, with 120k miles. Shifts are firm and properly firm when the throttle is lifted to force shift. 1-2 at 4000, 2-3 4000, 3-4 4800, 20-23 mpg driven med-hard by 3 drivers city and expressway currently 50-50 wvo-k1 mix. I changed the exhaust to a pipe and proper single muffler. (nice sound) Ed in Chicago Allan Streib <[EMAIL PROTECTED]> wrote: "Zoltan Finks" writes:

Or > a delay when shifting from Drive to Reverse? I think either one. In my car (the '83 300D) there is a delay of about a second when shifting to reverse from either park or drive. I always assumed it was by design to let the gears stop turning one way before they start turning the other -- a bit of "forced" neutral. > And can the delay be expected to be longer if the tranny is cold, or > if it hasn't yet been run through all the gears that day? I've noticed a bit more delay on really cold days, but not significantly so.

Mine does that -- I always use the parking brake to keep stress off the transmission.
