Tranny fluid disappearing?

[jokyfo]

1994 3.1 Automatic tranny 4 speed

Using tranny fluid. No leaks under car (not when just sitting and running anyway).

Where else can tranny fluid go?

?????????????????

Thx

check your radiator, the trans cooler may be leaking.

Radiator checked, looks ok. Do I have a vacuum modulator on that tranny?

You should. rignt on the front driverside. Pull the vacuum line and check for fluid in it.

I pulled the line and there is no fluid in it. No fluid in the radiator, no fluid under the car,...is it coming out while I'm driving?

It's kinda tough to diagnose a leak while driving from here. You are about 3,000 miles away and it's tough to see if the subframe and underside of the car is wet. Know what I mean? :th_winking: You need to do some looking and investigating to help us out here. You are our eyes, ears and hands.

To find transmission leaks you'll need to drive around then park it and check all the lines. The lines are under a lot of pressure and the leaks only appear when pressurized.

The lines should be wet if leaking. Running or not, if it's leaking enough to notice on the dipstick then it should be visible.
