Mein Auto: E46 328i
Transmission Problem Gear 5 Ratio Incorrect Code 0735 ?

Hoping someone may be able to Help! '99 E46 328i

Had a "warning" Gear with an exclamation! in the center of the gear come up next to the Digital (P,R,N,D) indicator on the dash.The tranny felt like it might be bogging down?
I had to give alot of Gas Pedal to move forward.(I believe it may have been stuck in 5th gear)
I turned to car off, waited a min, and then started the car, and the warning indicator was gone?

Drove the car and all seemed fine! I immediately took the car and had the transmission fluid flushed.( for all those wondering about the "lifetime fluid", it was really a nasty color black @ 125K miles) Car drove fine.

Anyway, a few days later the warning light appeared again and the tranny did the same thing, except this time the engine "check" light came on. I pulled a single code P0735 which appears to be a "Gear 5 ratio incorrect" ?

Does anybody know what this is?, and if so, any suggestions?
Any help appreciated! durbanite@aol.com
Thanks

OMG, why no body replied?????
i have the same situation!!

An experienced engineer in a shop told me to replace the tranny, and also told me the transmission oil change wil not solve the problem.

I don't want to spend $3500 on my old 99 323i with 116K miles....so I am looking forward there is some way to fix the transmission problem.......

thanks in advance -- please help!!!

Durbanite1. If your transmission fluid was black, then it
was burnt. Something had to happen to it for it to be black.
If you only had a pan drop filter & fluid change, then half
of the black burnt fluid is still in there. You may have to
change it again to see if it helps or get another opinion.

You can order various transmission parts from OEM.com or other sites. I would change the speed sensors in the tranny if I were you. There are 2, a front and a rear, same part numbers. You will also need a filter and new fluid as well if you take the transmission pan off. I would try this first, only about $400 rather than complete tranny change.

If you follow the wiki to the "T", while you have it laid open, change the sensors.

Yes, there is a speed sensor in the front and one in the rear (depending on tranny type). Figure out which tranny you have and then go to www.realoem.com and have a look at where they are. My tranny is here http://www.realoem.com/bmw/showparts...97&hg=24&fg=15 They are held on by one Torx bit screw. They plug right in to the wiring harness.

It seems to be that the error code is link to more than one possible issue as I have read that, yes in deed it can pop for a transmission oil level issue but also for throttle position sensor etc : (
