Tranny or Electrical

New problem...205k miles...recently if the rpm's drop to low when starting out, there seems to be a bit of skipping...feels like the transmission. It's seems I have to be in lower gears at lower speeds than ever before. Hope this makes sense...always tough to explain.

Thanks in advance for any suggestions.

Do you have "trans failsafe" on the dash readout or have any codes?

Has the trans fluid ever been changed in spite of the "lifetime fluid" sticker? Have you noticed any leaks? It could be worth checking the fluid level per the Bentley Manual. Low fluid could cause slipping due to air in the system.

Ya.. it's hard to know what has been checked from this end. Just covering all the bases. If all usual suspects have been ruled out I would suspect the torque converter or worn frictions. However both should show up in GT1 or INPA as gear slip or input/output speed mismatch.

Why the electrical portion? Did you check the resting battery voltage and idle?
Is this auto or manual?

If I am understanding correctly if the rpm of the engine is low it feels like it is bogged down. Is this only when in gear or also in neutral?

Manual tranny...only in gear and it's not like the bog you feel when starting out in the wrong gear...it's more like a skipping. Feels like electrical but can't seem to pinpoint. Doesn't happen any other time. It't fine when at cruising speed.

Make sure your battery and alternator are working properly. Always start there before searching for more complicated factors. Alternator should be putting out somewhere between 13.8 and 14.1 volts. The battery voltage at rest (car not running) should be around 12.7 volts if fully charged. There are charts on the web that show state of charge vs. resting battery voltage. Give this site a view.

http://www.energymatters.com.au/comp...age-discharge/

Most cars do goofy things when battery voltage gets low.

My 97 manual 528i was doing this for a a while with no codes. I thought maybe clutch related. Code came up one day and I was able to read it as Cylinder 3 misfire. Shut the car off and back on and drove the rest of the way home. Swapped out the coil and haven't have it happen since.
The code came up a few days before and I didn't have my reader with me. If I shut the car off and back on, the "slipping" went away, along with the CEL. When I got home, the code wasn't stored either. The code only came up twice. I actually drove the car for a couple weeks with the slipping feeling which why I was leaning towards clutch issues.

My sons 99 528i auto just went through the same problem yesterday. Same Coil number three as my 97. I checked the code and verified by swapping it with number 1. Problem followed. New (used) coil and ten minutes later, car was running fine.
