no OD and trans fluid leaks

92dangaranga · Apr 19, 2016

My 92 4.0 leaks trans fluid and always has since i bought it, and its never gone into over drive. i have been driving it in drive since purchased, burns a little more gas but gets from point a to b. my question is what could it be inside the trans causing it to do this. and this might sound stupid but i pulled the intake house off the tb and i swear there is trans fluid in there but my air filter is dry, where is it coming from. PLEASE HELP.

Where is the tranny leaking? Pan or at the bell housing? If it is physically leaking it has to be a seal. As far as tranny fluid in the intake it is impossible as they are 2 completely separate systems, there is no link between the internals of th etranny and the internals of the motor other then the tranny cooler in the radiator and you would have water int he tranny or tranny fluid in the cooling system. What I suspect you are seeing is motor oil up in the intake.

Thank you for helping. It is leaking where the trans meets the motor i believe. not to familiar with the whole technical terms and what everything is but it does loose trans fluid and it does not go into OD. And ofcourse a new one or "refurbished" one is close to 1800 dollars so ive just been driving as is and throwing fluid in every other day

Well, not to put too fine a point on it; but, RockAuto lists a modulator valve for the 92 4.0, automatic transmission. And a modulator valve uses engine vacuum to operate.

So, of course, there is a connection between the engine intake and the transmission fluid. It is the vacuum line that connects the transmission modulator valve to the engine intake manifold.

And, to top it off the modulator valve controls the transmission shift points. And, if the modulator valve diaphragm fails the engine will suck transmission fluid into the engine and burn it. It will also get all over the insides of the intake.

So my best guess is that the modulator valve has failed and is dicking with the shift points and trans fluid is being sucked into the engine to boot. They cost less than 20 bucks and take about 10/15 minutes to install, https://www.rockauto.com/en/catalog/ford,1992,ranger,4.0l+v6,1137855,transmission-automatic,governor+/+modulator,8500
