SOURCE: 1995 cutlass supreme transmission

It physically will fit and bolt up,but there are many different ratio,and drive and driven sprocket tooth counts,different final drive ratios,all monitored by the computer with electronic speed sensors.If the trans from the 95 has a different ratio than the 93,the computer will set gear ratio error codes,and possibly put the trans in a failsafe mode,stuck in 2nd or 3rd gear.On the transmission case,down by where the passenger side axle would go in,is a thin metallic tag,maybe 2"x 3",and it has bar codes,and also a series of numbers and letters.The numbers and letters,large cap,are the final drive gear ratio code.They should match on the two transmissions in question.

SOURCE: 1993 olds cutlass supreme 3.1 multi port loading up at idle

Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

The turn signal flasher is mounted in a clip on the right side of the steering column support bracket. The hazard flasher is located in the component center, under the instrument panel, on the right side. Replace the flasher by unplugging the old one and plugging in the new one.

Fig. 2: The main fuse block is in or under the glove compartment

The Main Fuse Block is located in the underside of the instrument panel, in or behind the glove compartment. Remove the access cover in the glove compartment to access the fuse block. Spare fuses and a fuse puller should always be kept here. Various convenience connectors, which snap-lock into the fuse block, add to the serviceability of this unit.

Convenience Center
The convenience center is located under the instrument panel, on the right side next to the fuse block. This unit houses circuit breakers, relays, chime module and hazard flasher.

Hope helped (remember rated this help) Good luck.

The RPM on my 1996 Saturn runs between the numbers 2 and 3 and stays at the same RPM when sitting idle. Any ideas what it could be?


Thanks for choosing FIxYa and welcome to the site. Check to make sure that your idle control is set properly. It may be set to high, thus causing to have high rpms. If it is correct, it may be your idle control sensor or possibly a map sensor. I would check the idle sensor before the map sensor. Thanks for using FIxYa.

Jumping and bucking RPM'S FALL OUT.


Start with checking all of your vacuum lines. If that isn't the problem it might be in the computer.
