1995 SL1 auto transmission
Just recently in hot weather and stop-and-go traffic my '95s transmission
with 137,000 miles started to skip 3rd gear. It would rev high in second and then finally shift into fourth like nothing was the matter. I stopped for a while (to cool it off) and then it shifted properly. Soon after I got up to 55mph again it slipped out of fourth gear and I was pulling about 6500rpm. I quickly pulled over and kept my speed below 30 (good for second gear under the circumstances I thought). When I couldn't avoid the highway anymore (after a couple miles of 25-30mph) I entered the highway (55mph) and it shifted like nothing was wrong. I know that the car doesn't shift into fourth gear during the winter until a proper temperature is reached, thus being in third gear for extended periods of time here in MN. I was wondering if this could have a wearing effect on "third gear"? Most of my driving is at night out of heavy traffic (65mph) and this has not happened then. When I do drive during the heat and heavy traffic though is when I am concerned something serious could happen. I have also experienced the "reverse slam". Any insights will be greatly appreciated because I know a new transmission will probably cost more than the car lists for. Thanks in advance, Pat |

Sounds like the transmission valve body is clogged (reverse slam) and you
may also have a failing valve solenoid (3rd gear) as well. Check the Saturn Forum web page and search for "reverse slam" to find Wolfman's proposed cure. It is cheap and easy and certainly worth trying before you pay for any expensive transmission work. Web site: http://www.saturnfans.com/forums/arc...p/t-23670.html Regarding the valve solenoids, you may need to wait for this to fail completely to be able to diagnose it accurately. The new fluid and filter from the reverse slam cure process may solve your problem though... By the way, the reverse slam is indication that you do not do routine maintenance on the transmission. If you change the fluid and filter often, you can usually avoid this problem.
