Randy, I would stay where you are unless you want power at take off. IMO that consumes more gas. So, if you want more power, you might want to consider a tune up. Do you know when it was last done? Besides, regular servicing is also very important. Good luck.

SOURCE: Sluggish Tranny through 1st and 2nd, when I get to 3rd it is fine?

Transmission seems to be slipping and may need to be rebuilt. This transmission may be stuck in a high gear and the on way to repair is to have it rebuilt. Good luck and thanks for using FIX YA

SOURCE: 4L60E won't shift to 3rd on 1993 Chevy Blazer

Hello;
It sounds as though your trans is going out. How is reverse? If reverse is real strong then you may just have a solenoid going out. Drop the pan and change the oil and filter if you are comfortable doing that. Inspect the pan for metal shavings and contaminents. Otherwise it would need to go to a shop for repair.
Thanks;

SOURCE: 1993 olds achieva-gears won't shift-what sensors on transmission

Had this problem when I rebuilt my engine. Turns out, that I had plugged back in a sensor that was previously unplugged. There is a known manufacturer's defect on some Achievas where a sensor on the transmission was mounted upside-down. Symptoms caused by this are primarily the car staying in gear (and thus stalling) when stopped, and failing to downshift while slowing down. Just unplug this pesky sensor, located roughly underneath and to the battery side of the throttle body. Be careful, though, because I don't know if running long term in this configuration will lead to transmission damage (although my transmission doesn't show any signs of troubles now that the thing is disconnected.)

I HAD THE SAME PROBLEM WITH MY CAR. 93 LS 400. THAT WOULD BE YOUR FUEL FILTER OR THE FUEL PUMP GOING BAD. TRY CHANGING THE FILTER FIRST. THE DEALER TRIED TO CHARGE ME $980 TO CHANGE FUEL PUMP.

1993 LS 400. Starting out the car just is slow. It's not the tranny. Tranny shifts perfect including reverse. I smell gas. Old lady drove car the whole time. 118,000 miles

IF WHAT YOU SMELL IS RAW GAS THAT IS AN URGENT PROBLEM THAT SHOULD NOT BE PASSED OVER. IF YOU SMELL A ROTTEN EGG SMELL THEN YOU MIGHT HAVE A CATALYTIC CONVERTER PROBLEM THAT GIVES POOR ACCELERATION. CHECK FOR FUEL LEAKS AND CHECK FOR ENGINE VACUUM AT IDLE. MUST BE AT LEAST 19 INCHES,. IF NOT, YOUR CONVERTER IS PLUGGED.

Car won't up shift or down shift at hot temperature

your tranny shifts according to pressure the transmission control unit regulates the pressure to provide smooth shifts you need to take the car to a good tranny shop that has a scanner that can check the shift points

Transmission Problems?

An automatic transmission with 300,000 miles on it should be in some kind of record book it's unheard of !!! It seems counterintuitive but changing the fluid on a tranny with this many miles can be the death knell. I have seen it many times but if you got that many miles out of it was on deaths door anyway. If you are really attached to it don't even think about a junk yard tranny, they will be just a little less worn out that the original in you car now. FYI it's going to be at least 2G's to have it rebuilt.

I have a ls400 1993.My car starts fine. But when I accelerate it moves very slow them picks up speed after a few minutes. repeats at every stop... Please help.

Throttle position sensor may be faulty. They do not always show fault codes.

There is a vehicle speed sensor too that may also be at fault. but the TPS is easier to get at initially.

WHEN VAN FIRST STARTED TRANNY WONT SHIFT NORMAL. AFTER WARMED UP AND TURNING OFF IGNITION AND RESTARTING ITS FINE. COULD THIS BE A CENSOR?

I would say it's not likely to be a sensor. Be certain your transmission fluid is full, and always allow your vehicle time to warm up in the winter months. Older cars such as yours tend to have high mileage, and most never even get a routine transmission fluid change, so you may consider replacing the fluid and filter to help extend it's life and performance.

My 1991 Saab 900 is shifting perfectly except it will not go into

I've had a similar problem, and it was the rubber bushings in the shifter link; as some particular ones age they get sloppy and 5th gear seems to be the one that suffers. Others will age and disintegrate, then you won't be able to shift at all. If all the other gears are fine (no grinding, judder, popping out of gear or other untoward behaviour) I'd look to these rubber bushings, and replace them all while you're at it. They're replaceable at much less cost than a tranny rebuild, and are most likely that cause, i.e. after rebuilding tranny, you still won't get into 5th because the shifter won't have been rebuilt, just the contents of the gear box!

Check the "Bentley Bible" aka the Saab 900 Official Service Manual, costs about $40 from Amazon, for info, it's an invaluable resource!
