tdk930s

Hi everyone
I wonder anyone one has this code before ? What happened to me is right after i have a shop guy changed my transmission fluid, i felt the car will jerk a little when i switch from difference mode while the car stand still. and i though that is normal for the new fluid. Today i use a OBD2 scanner to scan the car ,it has a P374A code comes out and it can"t be remove. i wonder could it be the fluid over or under filled to cause that code comes out ?
Please advice..
Thanks

I’ve had it appear a bunch of times.

I still have it today, apparently it’s permanent at this point. Never got a conclusive answer but car’s been running great for years so I’m not worried about it.

So you think the little jerk is fine when i switched through the modes (from M to C ) ?
cause this is the first time i have changed the transmission fluid (65000 miles)

I never got a jerk from changing the transmission selector. Of course it’s also been exclusively in Manual for the past 4 years so maybe I wouldn’t know. Not going to try either.

can you permanently keep it in manual? or do you mean you just instantly pop it into S->S+>M as soon as you fire it up? Id love to know if there was a way to be in permanent M mode

As to the OP - occasionally when i pop it into S>S+>M i notice the car makes a tiny movement, and a little noise, has to be very quiet to notice. I definitely wouldnt call it a jerk and I assumed it was normal when switching between modes.
