Gang

I have a '98 740i and just recently my transmission started
to act up.

I have 3 shift programs: Adaptive (also called Adaptive Transmission Control, or AGS), Manual, and Sports (A, M, and S/4).

The default at start is always Adaptive - until recently.

My car now starts in Manual (M), and even if I press the switch to Adaptive (A), the car immediately shifts to Manual (M) when I come to a stop (like at a stop sign), and it stays there. I press the switch to Adaptive, but the car goes back to Manual once I stop again.

It never did this before. It always stayed in Adaptive (A) mode.

Any hints or suggestions for fixing would be appreciated.

Could be a malfunction of your A/M switch located near the shift lever........

remove shift lever boot, pull up all the way around the outside perimeter on the leather and it will pop up. reach inside with your finger and pop up the A/M switch, disconnect the wire and soak switch in hot water with kitchen soap, soak several times in hot water to rinse and finally soak in rubbing alcohol to displace water. let dry and reinstall, if this does not solve problem, replace switch.

enjoy the ride........

I would second the switch theory. Often times those things get drinks, debris and other stuff in them which eventually cause them to go bad. They also fail on their own eventually. Without just buying one and replacing it, the only other way to check it is with the dealership diagnostic tools.

Thanks for the advise, guys.

I'm soaking the switch as we speak, and trying that before buying a new one.

Will let you know how it turns out.

Jyep and EXtech

You guys know your stuff.

I removed the switch and soaked it as suggested, and it worked like a charm.

I really appreciate your assistance.

Thanks a bunch.

Hey guys does the same thing apply with the Trans on a 93 740i. My car sometimes dont move it seems as tho the brakes are on and if i press hard on the gas it releases but if i stop at a lite it does the same thing, and if i stop for more than 5 seconds. but if i switch my trans to the snow position( *D) it doesnt do it at all. Any Ideas.
