Answer:
Your transmission is probably just wearing out, due to age and mileage. BUT, if you can find a good transmission man who really knows those Benze trannies, he might be able to adjust the bands to make it shift better for a while. As for the AC, just have the system converted to 134A refrigerant, you use an 80 percent load compared to the R12, and put in six ounces or so of PAG refrigerant oil (as the old mineral oil with R 12 does not mix with the 134A refrigerant.)
