delayed tranny shifting fro 2-3 on 123 1981 300D

I recently purchased 1981 mercedes 300D. I am having trouble with tranny shifting from 2nd-3rd gear. It seems to have a significant delay. The rest of the other gears shift as they should. I would appreciate help with this problem. My other 123 TD 1984 has the same trouble with the same gears except the delay is about half of the 300D.

84 300D acceleration concern

I test drove 1984 300D with 240K miles showing. She cranked and idled for approx 15 minutes. The dealer alerted me of sluggish acceleration. This was an under statement. I got her on the road and she barely made second gear, so I floored it, engine rev'd higher, pedal to the metal produced maxed speed of 45MPH. Easying off the gas seemed to help shift gear. I ran out of road, brought her back and same thing. asked dealer if he had any ideal what was causing the problem? He says... Fuel filter or maybe the turbo is going/gone bad. Question...

A/C turns to heat on downshift '82 300CDT

This question has been driving me crazy since this summer.

The A/C on my car works fine until I am forced to slow down or come to a stop, when this happens the A/C quits blowing cold and starts blowing extremely hot air, hotter than the highest heater function. My theory is that the phenomena happens in conjunction with a downshift in the transmission but beyond that I don't know what to do. The dealer wanted to start throwing parts at it but that can be very expensive without knowing. The compressor seems to be ok.

Help would be appreciated.
