Upshift auto transmission 240D
My transmission will upshift fine if I don't get on, if I step on it will slip between shifting points. Is there any easy way to correct this?
I purchased this car with a blown engine from a person in New Hampshire. The vehicle is in excellent condition except for cruise control and minor transmission problems. Thank you for any help you can provide in advance. 1982 240D automatic transmission 1981 240D manual transmission 1977 R100 BMW for speed manual Joe Comerford Cambridge, Massachusetts |

Upshift auto transmission 240D
If I let my car pick up speed gradually the transmission will up shifts smoothly.
If I step on it, it will slip between shift points. Is there any easy fix for this problem? Plus it will not downshift. Any help on this situation would be greatly appreciated thank you in advance J Comerford Cambridge, Massachusetts 1981 240D manual transmission 1982 240D automatic transmission 1977 R100 BMW manual transmission 1974 cub Cadet yard tractor |

The 1980 & later 240D's use vacuum controls & have a vacuum modulator.
There are several plastic on/off vacuum switches on the valve cover that can & will affect those shifts..
