Hi everybody. I own an 1987 300SDL Turbo, low km(165.000km).I have changed the trap oxidizer yesterday with the original Mercedes pipe,and the car runs better,it feels more responsive,powerful and more quicker than before. I love that.But,I have a question regarding the automatic gearbox.Here's the thing:When I switch the shifter from P to D,it needs a little time to get ready ( about 1 sec),and when I put it to R,it needs about 1,5 -almost two secs to get in the gear.And when I drive it feels nice,but when shifts it feels not very smoothly.It is not a very strong ,,shock'', but I don't know what to say,this is my first MB,and perhaps the old gearboxes are not that smooth at changing speeds as the modern ones.The thing is this: do not have a problem with that,as long as this behavior is normal.It could be just my concern and nothing more.But I don't know what to say at this point.Thank you, have a nice weekend and thank you in advance for help. Regards, Mike, Oslo, Norway.
