Which motor mount? The top one (Torque Axis Mount?) These seem to go bad
with time. Most often it is from the rubber shrinking under load and getting a large gap between the steel frame and the engine mount. This leads to slamming when the transmission shifts between gears. It is very easy to replace and the procedure has been covered here and in the Saturn forum before so Google for more info. The key is to use a jack to support the oil pan using some wood or a telephone book to distribute the weight evenly on the pan surface. You need this to raise the engine back up to bolt the mount in place. As to this causing your 3rd gear problem, I doubt it since you indicated it won't go into gear at all. On the transmission fluid, it is very important that you change the filter as well but you did not mention if this was done. As I indicated previously, after you have changed the fluid and filter, you can try the valve body cleaning procedure in the Saturn Forum (search on Wolfman's "Reverse Slam Cure"). This is basically adding your favorite transmission additive, then putting the vehicle into reverse and letting it idle for exactly 30 minutes with the parking brake set and while you are inside the vehicle. (It probably would not hurt to block the wheels as well, although this is strictly an added safety precaution.) After 30 minutes, stop the vehicle, and then drain the fluid again. In your case since fluid looked so bad, I'd also remove the spin on filter and dump the fluid from there too, then re-attach, tighten, and re-fill to full (do not overfill) with Dexron III fluid again. If this doesn't do the trick, you can try measuring resistance of the 5 transmission solenoids using the procedure I posted in March. All solenoids should measure identical resistance somewhere between 4 and 8 ohms if I recall correctly. If you get one that is way out of line (0 ohms or 2K ohms for instance, then you found your problem. If they all measure the same, then the solenoids are likely all good so it will be time to visit a good transmission service place. Make sure you tell them you just changed the fluid and what the old fluid looked and smelled like as this will be important to help them diagnose your problem. Good luck and remember to change that fluid and filter about 30K or so down the road! Bob |
