Stupid P0741 code!

I've searched a ton about this stupid code. Seems the majority just change out their torque converter. My 01 530i has 144k on the clock and this code popped up simultaneously with P0365. Coincidence? I've read how finnicky P0741 can be. The plug on my camshaft position sensor became loose somehow which triggered the SES and these two codes. The SES turned off by itself but stored the two codes. I plugged the camshaft position sensor back in snuggly but the SES came back on a few days/100miles later for P0741.

I'm taking it into an indy to further diagnose the problem hoping the P0365 somehow had something to do with triggering the P0741. Failures in valve body, solenoid, pump, computer, or sensors can also cause the code and sometimes a faulty MAF....my head is spinning from searching thread after thread.

Taking a shot in the dark here but has anyone had P0365 and P0741 come on? The car is running great and is NOT slipping in either auto,sport or manual mode and has been driven over 200miles since the SES light came on.

Not good news. Usually torque converter. See this post: http://www.bimmerfest.com/forums/sho...46&postcount=6

About $1500 to repair.

Well there goes my suspension budget lol. Thanks for the link and help guys. I've read through all those extensively while searching google for a few hours each night since the code popped up looking for anyone that has had 2 separate and unrelated codes pop up and one of those possibly triggering P0741. I am searching other car makes and models as well.

I'm still calling around for quotes and etc. When the cam position sensor/P0365 was triggered,from the plug coming loose, the engine really lost some power. Plugged it back in and the engine gained it's oomph back but P0741 has popped up twice after highway driving but there are zero signs of slipping. RPMs at 80mph on a flat stretch stay at 26-2700 RPMs, jump up to 2900 on an incline then go back down to 26-2700.

Tranny codes require a GT-1 or equivalent scanner to reset. When I popped a TRANS PROG FAILSAFE code on a wet rainy day, the dealer was the only one who could reset it. Naturally they wanted to replace the tranny. At 50K, I told them to reset and and kiss my a$$. The problem never recurred. Since you have no symptoms, try the proper reset and you may be in luck. Post back the outcome.

I had P0471 almost 2 years ago now. $1200 on rebuilt TC. As of today, the TC is still working fine. However ever since my TC was replaced my tranny has never been the same. I get slight jerkiness at slow speeds and lazy shifts sometimes. I minimize it by driving in Sport mode. I have learned to live with it and will drive the damn car to the ground until the tranny completely fails. Until then, I will consider putting in a new tranny and tc..
