Good evening all

I have a 1986 Mercedes 300 SDL 280, 000 miles. I just had the transmission rebuilt and I have noticed two problems.

1. The car is slower than normal and takes some time to reach normal speeds. Once she gets going, it will reach normal speeds. When I think about it, the turbo may not be kicking in either. The guy that did the rebuild said that the transmission I gave him to rebuild was slightly different from the one in the car. He said the one in the car was electronic Nd the one used to rebuild was a mechanical setup. He said he made the adjustments to the rebuilt one to make it work.

When I got the car yesterday, he said to check out the throttle body. That is why I am coming to the forum for suggestions ?

2. The speedometer and odometer isn't working. Neither was working prior to the the rebuild and still not working. The mechanic suggested I replace the speed sensor on the side of the transmission. I went to ths Mercedes dealer and they said the wiring harness is over $300. One of the techs at the Mercedes dealer suggested it might not be the wiring harness for the speedometer, kickdown switch and etc.

Help me on where to start....

Thanks in advance

Ron
