gear warning on PRNDL rough snifting Auto 323I

Any help is appreciated on this one. Car overheated on me on way home. Cut her off, let cool down and got her home. Its a 2000 323I, so I replaced the water pump, thermostat checked expansion tank, brackets hoses ect (replaced them last year). After the new parts were replaced, bled air out- test drove and the shifting was hard- driving and slowing down to stop. The gear light beside the PRNDL was on also. When I redid the cooling issue last year, I also replaces the Transmission thermostat. Any ideas what could be causing the hard shift and get the gear light off?

Scan for codes with a BMW scanner.
Did the light come on while overheating?
I don't see how that would affect the transmission.

don't recall that. I don't have a scan tool so maybe AutoZone or elsewhere can scan

It's probably unrelated to the overheat. Faulty accumulators can cause hard shifting.
A standard scanner won't tell you much.

Have you figured out what was causing the hard shifting? I just swapped out my fuel filter and fuel pump relay which fixed the issue I was having. but now the gear pops up for the transmission and it's shifting hard on acceleration and even harder while slowing down. I have an 03 330xi

hm.... perhaps you guys might want to try the transmission adaptation reset procedure. perhaps that'll help. it couldn't hurt it, i can tell you that. google it up to locate instructions. if you had the software and hardware, it would be a lot simpler and faster.

AUTOZONE OBD 2 scanner will not be able to read the BMW specific codes. Need a BMW scanner like P.A. Soft v1.40 to read BMW subsystem codes..
