how does a mercedes 240d automatic trans shift? vacuum , electric/ pressure?

Answer 1

there is a vacume modulator on left side of transmission tube color should be black and run to the vacume switching devices on the rear of the governor. there is supposed to be a rubber cap over the adjustment key on the modulator [if cracked or missing it wont work at all]
modulator modify's transmission governor pressure and controls upshifts; kickdown [passing gear] on these is controled by a switch [when throttle is fully depressed and a solinoid mounted internally to the transmission
while expensive these transmissions shift best with fresh MERCEDES fluid and filters. don't forget to drain the convertor when servicing

Answer 2

For the 240D, i've got not got faith they ever presented a 5 velocity handbook in even in Europe. They did furnish them interior the 300D's in a while i think over there. somebody did a conversion on the internet. The 240D does no longer have sufficient torque to tug a 5 velocity with a tall very finalchronic. I as quickly as owned an 'eighty two with a 4 velocity handbook and it grew to become right into a great motor vehicle. Now, the two.2 Liter 4 cylinder diesel vehicles interior the 190D's had 5 velocity manuals. although i'm uncertain of the compatibility of that transmission to the two.4 liter. I do have faith the 240D motor to be a extra appropriate motor than the two.2 interior the 190D. i could a minimum of study that transmission and doubtless you will locate some pointers on it. Sorry, i grew to become into no longer numerous help.
