I have a 2000 323ci Auto/steptronic trans throwing code p0735 - gear 5 ratio incorrect

I know what it does and all, but i need to know what needs to be done to solve the problem ):

Havent tried anything yet, but if anyone has fixed this problem before info would be highly appreciated!

Hi Steezy:
I had a same problem and here what I have done so far:
When I drive on highway, full gas, the transmission will change the gear just fine. But when I ease the gas it jumps back to 4th and stays there. It change the gear from 1st to 4th just fine. It does that when the engine is warm, when the engine is cold/ not warm enough I don't get that problem.
I recently changed the transmission oil, filter, and a gasket. It seems it got better and I get that problem less often. it also change the gear to 5th again when I slow down to 3rd gear and speed up again, which was not the case before changing the oil.

Let me know if you got some idea
