EOD 40 question

[Coltonreece]

Okay so I just got my truck running from breaking a tensioner pulley, which also caused my transmission cooler lines to leak from my belt snapping and smacking the lines. So I drove it to the auto parts store and on the way home my truck just stopped shifting from first gear, still goes in to reverse, and will barely shift into second. I’m assuming the leak was worse than I thought and I lost too much fluid, I made it back home. If I fill it back up with fluid should I be okay ? Will having no fluid (or low fluid ) cause no shifting ?

Yes low fluid will cause it to not shift. As for any internal damage, I guess you'll just have to drive it and see what happens. I feel that the less you drove it low on fluid, the less chances of having internal damage. Not to be negative, but you might think about starting to save for another transmission in case the worst happens. There's also a chance that your transmission will work fine for a while, but still have internal damage which shortens the life of the transmission.

You might be okay. A friend of mine once tried to do an oil change on his Toyota truck and actually drained the auto transmission, yeah real smart I know, but once the fluid was topped off to normal it drove fine. Hopin' your is okay too. I suppose it's worth dropping the pan to check for metal--might as well know if things are looking bad.

I should of dropped the pan first but instead just fixed the leak at the trans cooler lines and didn’t bother taking the pan off yet because no fluid came out so I thought it was completely empty, well I go to fill it up and get about 9 quarts in and it’s starts overflowing. I loosen the pan and drain about a quart and then see if it’ll shift. Won’t shift out of first, until I get it up to speed (20-30mph) ( takes about a full minute if it’s not downhill ) and it feels like it’s barley shifting and then real hard to let it downshift. Will it being overfilled make it not shift as well? Should I try to drop the pan and refill? If I do refill how will I know how much to put back in ?

By using the dipstick.

I think overfilling the trans can lead to blown seals so I would definitely drain some.

Isn't "EOD" "explosive ordinance disposal"?......what is going on around here? Our engines are "bulletproof", but probably not "ordinance proof"..... just sayin'.....

Overfilling the trans is just as bad as running it low.
High fluid level gets into the spinning gears, which then turns the fluid into a
pink mess as it gets churned up and mixing with air.
Bubble gum goo will not shift a trans.
Basic hydraulics is that fluid does not compress. Air does.
Compressed air will not properly operate or lubricate the trans.
Do not overfill.
