94 A4LD Explorer transmission loses fluid, but doesn't leak.

hey first time

Welcome to this forum! I've moved your thread into the transmissions section. Do you see transmission fluid mixed with coolant? There might be an internal leak in the radiator.

I assume it's an auto trans. If so I think there is some valve in the engine bay which has gone bad and is allowing trans fluid to transfer into the oil. I can't remember what it's called or where exactly it's located. I don't have a 2nd gen, or an auto trans for that matter, but I remember reading about the problem. Post a new thread in the "Stock 95-2000" section asking the same question. More people will see it and someone will know what it's called.

Welcome to the Forum!!

Edit: never mind about moving it, BrooklynBay beat me to the punch.

The 4R55E doesn't have a vacuum modulator like the A4LD.

i cant tell wher my trans fluid is going!!! but every 100 miles or so i have to add 2 quarts so she'll move. since the fluid loss started it smokes out the tailpipe alot but how could i be burning tranny?

Your post was merged into this thread. Let's keep all of the posts in the same thread.

Whoops. Having a clutch makes life so much easier, lol

 

[whyisshane]

thanks

thanks for the input after reading the tranny section for a bit i realized that the vacumm mod. thingy was letting fluid be sucked right into the intake. what a great help this forum was i had been thinking for days "how am i burning trans fluid" and was starting to think the two things were not related, anyway thanks and i hope i can help one of you sometime.

The 1995 & 1996 Explorers have a 4R55E transmission without a modulator. My 1995 Aerostar has an A4LD with a modulator. Are you saying that you have a modulator?

whoopsie

my explorer is a 94 not a 95 sorry for the confusion as far as what tranny it has, i am not sure. right after i read it i went out popped the hood located a steel vacuum line that loooked like it ran to the trans , unhooked and plugged it . and no more smoke . it does shift poorly, the local parts store will have my part in 4 days. do you know what tranny i have? its a v6

 

[BrooklynBay]

This makes more sense. You have an A4LD. I'm going to update the title of this thread. The part is called a vacuum modulator. Did you order the adjustable or non adjustable type?

 

[whyisshane]

non adjustable, should i have gone the other way? how long should it take to change? havnt been under there yet i have a van tying up shop space. is it the same as the turbo 350 pretty much?

Check the links in # 56 in my list of useful threads.

 

[whyisshane]

so i have deciced to go underneath to change my shift modulator and have to remove the exhaust. will hollowing my catylitic converter improve performance and will it impede any of my comp. controls and such. nothing under 95' has to get plugged in for inspection but check engine light cant be on!

 

[BrooklynBay]

Don't do anything that will be illegal. You need the catalytic converter.

 

[whyisshane]

do i have a down stream O2 sensor? with the mileage (170k) and since i cant afford to replace the cat right now would my performance benefit from installing a temporary test pipe? and would my smoking from the shift modulator possibly clog the cat? thanks!

 

[whyisshane]

so i installed the shift mod. and now my trans shudders on take off and shifts in and out of d to 2 constantly at higher speeds. it is adjustable but which way do i turn it ,and how much is a good start?
