ATF Smoke on 300-24 5th gear trans
 

Hello, some time ago i noticed white smoke going out from the exhaust, it´s ATF but don´t know which gasket blew off, no leakage visible from the under side.
Does it worth taking out the transmission or it´s something less complicated.
thanks
Enzo

if it is tranny smoke i believe that is a sign of a bad modulator on the tranny ... much simpler to change than the tranny itself. cheaper too.

i concur with prev post trans modulator has vacuum line.when diaphram breaks vacuum sucks fluid into intake and is burned.i have rebuilt several trannies because a bad modulator sucked the fluid dry but owner kept driving.[i am amazed at the number of people who believe that getting where they are going is more important than their wallet] david poole european performance dallas tx.

Modulator?
 

Thanks, but where is that modulator, or how can i reach it, is that a part that can be purchased alone, can it be rebuilt?

modulator
 

you will find it on the left side of trans about half way down from bell housing.you will need a 1/4 drive ratchet and 5mm allen socket and just be careful when you pull it out.david poole european performance dallas tx.

Trans out?
 

Hello David, do i have to take out the transmission in order to get that modulator?
I took the injection out and in the inlet manifold there´s a pool of ATF, some vacuum line is sucking in the ATF.

Modulator Out
 

Thanks for your help, i managed to take out the modulator and will buy it from the MB local dealer. I was upset for having a major maintenance on my engine and tranny last year, i spent some $4.000 and í´m not in the mood of having such a show this one.
