Question about 1998 Saturn SL
My mechanic put a used transmission in my 96 Saturn SL and now the gear ratios are all wrong. It revs too fast - it runs rpm 3000 at 70 mph in 5th gear, it used to be 2300.
It seems like the mechanic put the wrong transmission in, is that possible? I took it back to him and he adjusted the transmission cable but it didn't change anything (though he claimed it made it shift easier).
The original problem was that it wouldn't shift into first except on a lucky try and the problem was starting to happen with second gear too.
Is your car sohc or dohc ?
1995 to 1997 years are the same
1998 to 2002 years are the same
find out what year he put in

I have the same problem. on the passenger side under the fender you will have access to the transmission. Remove the cap on the end. You will need to drain the transmission fluid and replace all the gears in the end cap if damaged hopefully they are not and you can just tighten up the nut. What happens is a nut comes loose and backs off the pressure on the bearings and you loose 5th. I removed the entire transmission and opened it up. There is nothing wrong with the other gears, because your problem is with the 5th gear synchronizer assembly. I let mine go too long and I'm having to replace everything. Make sure you put the appropriate torque on the nut and hit it with a hammer to lock it down. This should really be designed with a different method of keeping that nut in place. It's costing me lots of time and now money at the stealership. Good LUCK.

Saturn says and I quote
there transmission fluid is not to be changed after the first change at 6000 miles.
Now I say it should be changed at every 30000 miles. If changing out the fluid doesn't work then you need to go to a transmission repair shop.

I had this same problem with my 1998 SL2 after about 170,000 miles. There is a plastic bushing at the end of the shifter cable that holds the cable to the shifter - it probably broke. Remove the center console inside the car to access the bottom of the shifter. I checked my local Saturn dealer to find the replacement cables (come as a set) are more than $200. So I went to Lowes and bought a beam clamp and a large washer to hold the cable to the shifter. It has been working fine for more than 28,000 miles and cost less than $3

Now i dont know a lot about automatics especially modern ones with all this fancy electronics thats used nowdays but i think its a fault with the temperature sensor for the gearbox.But where its located and what it looks like i have no idea it could even be mounted inside the gearbox .Sorry not a very good answer from a mechanic but?? very few of our europeon cars come with auto transmission .Evan when i do know whats wrong i cannot buy the parts for the gearbox as only re-con boxes supplied by the dealer so best advice is to try a specialist in auto box repairs only .PS some of my best students when i used to teach mechanics many moons ago were the girls so no excuses like iam only a girl please
