BMW Z4 2.5I 2003 AUTOMATIC TRANSMISSION NOT GETTING INTO DRIVE ERROR CODES : P0700 P1732 P0715 P0721

[DANIEL_MR]

hi guys i just bought my first Z4 ,

my only and main issue is that the transmission wont drive forward but goes into revers smoothly i got this codes :

P0700 - TRANSMISSION CONTROL SYSTEM (MIL REQUEST)
P1732 - ?
P0715 - INPUT/TURBINE SPEED SENSOR "A" CIRCUIT
P0721 - OUTPUT SPEED SENSOR CIRCUIT RANGE/PERFORMANCE

i think that the main issue are the sensors but since I'm new at the BMW world i want some help in this field.

:!: :!: anyone that had this same problem before that had it fix that can help me out :!: :!:

should i go to my local trany place (I'm almost 90% sure that the will want to replace the transmission) or try to do it my self?

update on the issues, i did the transmission reset and clear the codes before turning the car on and it got it out of limp mode.

i drove it for about 3 miles and everything was smooth :driving: until the las mile the car start to hold the gears and the transmission light was back.

i checked the codes again and showed P0733 ( gear 3 incorrect ratio ).

after some research i will try to do the filter, fluid and solenoid change to see if this fix the issue ill keep posting the results.

It's a shame no-one has been able to offer advice from the forum, but I thought you at least deserved a reply and thank you for giving us the feedback.

And more importantly, welcome aboard.

It’s back to life end up finding a transmisión for $300 shop charge $400 and it’s running smooth
The downside now is that is taking long cracking before it turns on might be the pump because it won’t turn on if it’s at 1/2 fuel tank
