E40d dumping fluid in exaust?!?!?!?! Help!!!!
So on my 95 f350 5.8 2 wheel drive,so far with my expert resources ( you tube) I've maybe narrowed it to the trans modulator value but where is it and does my transmission even have that not sure replaced all vacuume lines and this problem is what killed the last transmission I didnt know it was really happening thought I blew a head gasket from the smoke but now with new trans and clean fluid I see it IS transfluuid burning up in the exaust but wtf and how? The modulator suspect #1 one armed man #2....any more ideas please help if u can thanks

Not sure if your trans has a modulator, but if it it does, it's vacume controled, and if it goes bad, trans fluid will be sucked into the intake manifold and burned, it could be on the back of the trans behind the pan, or on the right side, most are gold or silver, small with a vacum hose either on the end or side.

Vacuum modulators went away in the late 80s when the C6 was retired. The E4OD is electronically controlled.
There should be no way for transmission fluid to get sucked into the engine unless, perhaps, someone who didn't know what they were doing connected the transmission's vent hose to the intake system.
