ATF Replacement on a 1994

Hello all,

Well, my baby has served me for nearly 2-years and 50,000 miles but now I believe I may have screwed-the-pooch. My tranny had always been iffy; it took a good 5-miles of driving in the morning in 2nd-gear before it'd drop into the higher ones. Well, this weekend, I decided against reason to add some tranny-fluid stabilizer. After about 150- miles and on my way home from work, I noticed going up a hill at about

60, it wouldn't get out of whatever the second-to-last gear is; revving at about 3000 RPM. I looked in my rear-view mirror and saw an ominous blue cloud of smoke, and my rear window began glazing over with oil. I figured I'd blown a seal, but wasn't all too sure if it was engine or tranny oil. I got home, and had a restless night of sleep, and this morning I hoped against hope that it was my engine- oil. Realizing it was ATF, I started the engine, let it warm up, and tried to put it in gear, which it did, but only VERY reluctantly. I decided I was screwed indeed, and decided at a last resort to replace the old fluid.

I've followed the advice posted here:

SPECIFICALLY Greg J's, which is at the bottom of the page. I have everything ready, and when I start the engine (in PARK), only about half a quart of old ATF came out, and even though I'd siphoned new ATF down the return tube, there is no suction. Advice anyone? I love this truck and would hate to have to send her to the glue-factory.

When a trans sounds to be in the shape yours sounds to be in, it's a wee bit late to worry about the fluid...

Sorry...

I'm not quite sure I understand what you are describing. Do you think it's burning ATF? Do you have loose/disconnected vacuum fittings on the cluster on the intake manifold? If you remove a vacuum fitting from the cluster do you see red ATF on it? Are you losing fluid?

Chances are you need a new/rebuilt trans but perhaps it's a bad vacuum modulator.
