tranny
 

Hi all,

Just a question about MB tranny's. In cold days my tranny has problem shifting gears, this happens in the first 5 or 8 minutes of of putting the car on D. I called my MB tech and told me that is normal and all new MB tranny's need to warm up, is that correct?

Thanks

Yes.

Designed to promote a few higher revs to speed engine warmup.

Thanks

I assume this is on the 300TD?

The transmission on the car is programmed to delay the upshifts following a cold start.

This is done for cold start emmissions to warm up the catalytic converter faster.
