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.

It could either be the linkage inside the door popped off, or the outside handle is broke on the inside of the door. this is common with this car and is very fixable.

Your instrument cluster ground wire may be the problem. Remove the cluster and trace the black wire to see where it connects to the chassis. Clean and tighten the connection. If the wire is damaged, splice in a new wire.


  1. If necessary for access to the battery, remove the air cleaner assembly.
  2. Disconnect the negative battery cable.
  3. Remove the instrument cluster trim plate.
  4. Unfasten the bolts securing the cluster to the carrier.
  5. If equipped, remove the automatic transaxle control indicator cable.
  6. Pull the cluster forward, detach the electrical connector, then remove the instrument cluster from the vehicle.
To install:
  1. Attach the electrical connector to the cluster, making sure it plugs in securely.
  2. Place the cluster into the carrier.
  3. If equipped, install the automatic transaxle control indicator cable.
  4. Install the cluster retaining bolts and tighten to 18 inch lbs. (2 Nm).
  5. Install the cluster trim plate.
  6. Connect the negative battery cable.
  7. If removed, install the air cleaner assembly.

Digital instrument cluster to fix

Hmm, that car is now 23 years old. My first run-in with a digital dash was on my son's '89 cutlass supreme, that about 15 years ago. It was doing the same as yours. I asked an Old's dealer, and was told if I took it off, they could ship it out somewhere to be fixed. I asked how much. He said, " well...not sure exactly, but's pretty expensive." Chad, when the dealer admits to you that a repair is "pretty expensive", you tend to gulp, and look for the door! I did. We wound up with another dash from salvage, and it had only half the problems as his old one. But it worked for the most part, was ok.

If you really want it fixed, I'm sure someone somewhere could fix it, and it's older technology now, might not cost so much, maybe a computer geek could even fix it. Just keep asking around, if you don't want to try a used one as I did. Problem is with finding a used one, a lot of salvagers send lots of low-demand cars older than 7 or10 years to the crushers. Good luck.

Instrument cluster black

If you have the 3-Panel Digital Cluster, with the Fuel on the Left.., Speed in Center.., and Odometer on the Right.., and the Cluster is going Wacky.., works one minute then craps out the next.., take the dash apart and remove the Digital Cluster. Take your time when unplugging the harness behind the cluster, use a mirror if you have to.., to unplug it correctly.

The problem with this Digital Display is the Solder Connections.., at the 14-Pin IC Chip.., which is directly behind the Odometer Display on the main Circuit Board. When you get the Cluster removed.., again.., take your time.., and take the cluster apart.., so you get the main circuit board out. The 14-Pin Integrated Circuit (IC) Chip is marked with an IC2 on the main board.., which as mentioned is behind the Odometer Display. The IC Chip is usually Black in Color.., and is '@' 1/4" x 3/4" You will need a Soldering Iron.., @ a 30 watt with a pointed tip.., don't use a Soldering 'Gun'., too hard to use and too hot.., you don't want to cause yourself more problems by messing up the board circuit tracks by overheating them.., so it's best to use a smaller iron. It is a good idea to have some fine strand solder on hand.., but you should not need it.., all you want to do.., is to 'Re-Tin'.., or 'briefly' melt the Solder at all 14-pins of the IC Chip.., on the back side of the board.., to Re-Flow or Re-Solder the Connections of that 14-Pin IC Chip to the Circuit Board. That's all it is..!!!

I just repaired my 1991 Olds Cutlass Supreme 3.1.., 3-Panel Digital Instrument Cluster in this manner.., and it has been "Perfect" for a month now..!!

Take your time.., get it all back together.., and my bet is that it will be good to go for many more years to come..!!

Good Luck.
