E34 92 525i "trans Program"

Help..."TRANS PROGRAM" displays on dash. Car was running great. PArked for a few days and "TRANS PROGRAM". Checked battery, alternator. What is next ? Have read all trans posts on this site. Can it be the TCM , speed sensor, or gear selector switch ??? HELP! Cleaned gear selector switch and "trans Program goes off then comes on when I accelerate to pull out of driveway. Tried unplugging the TCM to see if it would make a difference and it is still the same.

Try the switch again. Make sure the tracks look good and the wiper makes solid contact. If that does not help check the codes from the trany. See if there are any stored problems.

Look up the error code. I would replace the transmission/differential fluid and transmission pan. Red Line fluid usually clears up any oddness with the transmission. Then reset the ecu/unplug battery and see if the fault persists. If it persists, then you have bigger problems.

91 525i with same exact problem

Hey. I have the same exact problem with my 91 525i. trans program. I tried changing the automatic manual switch, and that didnt help. I think it is probably the shifter because it is kind of loose and sometimes when it is in drive it thinks its in neutral. When I accelerate from 2nd to 3rd gear, it doesnt go to 3rd and then flashes the trans program. Then it is stuck in 3rd gear until I shut the car off and turn it on again. I'm thinking I need to replace the shifter or clean it or something like that. If anyone has some advice for me, that would help because this is frustrating.

Most serious provoked transmission problems are caused by wrong oil/lack of regular oil and filter change.

Most serious unprovoked transmission problems are related to valve body issues, and is very commonly construed as slipping clutches.

Have you taken your car to a transmission specialist shop ?

Have you had your TCU scanned for error codes ?

Have you reset all the error codes on your car using a computer including the transmission computer, by unhooking the battery and key2ing the ignition for a few minutes ?

What is your maximum budget to reliably fix your transmission ?

How many miles on your tranny ?

And what do you mean by slipping ? Please describe the exact tactile perceptions that you experience, as vividly as possible.

Finally, when you changed your tranny oil recently, what was its colour ? If the colour was brown or black, could you determine its original colour when new ?

What is the exact model of your transmission, according to the tag on the side of your tranny? If there is no tag, then goto realoem.com and plug in your vin number in the appropriate search engine, then look through the diagrams that show up, select automatic transmissions, and then try to find the right tranny if there are many listed.

Is your TCU (transmission computer) located in the rear right footwell, or together with your other dmes behind the right shock tower in the engine bay ?

If you can get at it, you can use the tcu's part number label to determine the exact tranny that you have.

1995...you should have both egs and ags if it was a zf box. Not sure about GM but I'm not surprised if they had their own version of this. This should enable your car to adapt effectively to clutch wear. It was a revolutionary period in auto transmission evolution. A specialist with a computer may be able to bump up the software programming in your tcu and help you fix this problem. May.

Lets see if we can salvage this for ya.
