1995 525i (US) TRANS PROGRAM HELP!

[Unregistered]

Long story short - I have checked all of the most common web pages for this issue (Bruno's is a big help but did not fix this particular issue) - but - I still get intermittant trans prog message on the display which started this Xmas. The transmission has always worked fine and still does even when the message is displayed.

So far, the following has been done (at Dealer):
(Transmission was rebuilt by dealer 20K miles ago)
1) Replaced the circuit board that controls the dash instruments (cluster) - no effect...
2) Temporarily swapped the check control module with known good - still no change
3) Swapped out the transmission control unit - no change
4) Pulled the pan off the tranny to inspect for internal wiring flaws/shorts - nothing
5) Ohmed out all the cables and put it on the CAN analyser - no issues found
6) Battery is good (and on charger) when testing (fails either way)
7) The transmission switches (A-M mode and position switch) have been cleaned and seem to be okay

This is where we are now stuck!!!! This is so frustrating - anybody have any suggestions?
(I did see the post about checking the 50A fuseable link which we will check)

Makes me want a Mazda again... Well maybe a 328

Thanks,
Scott

Hi Guest.
So apart from the TRANS PROGRAM message, are there any other symptoms?

No other symptoms - the transmission always works flawlessly. The Trans message is accompanied by the bell but the car works fine. (Trans does not go into limp mode!)

Thanks,

I have experienced a similar problem. I am planning to change the tranny speed sensor to see if it would make a difference.
