Transmission pukes oil from input.

[shannondeese]

I have a problem with my transmission. When I fill it up to the rim of the fill port, for the next few hundred miles it pukes 90wt when I stop. It all drains out of the hole in the clutch cover. It leaks until it's about 1 to 1 1/2 inches below the fill port. It has been doing this for about a two years. Is there any way to get it to stop or is it ok to let it run a little low. Thanks.

Pull the trans and look it over. Your front cover may be loose or missing bolts.

Obviously after 2 years, it is not going to heal itself.

Common problem, search will return a lot of info. The fix typically is a new input shaft cover. It's a close fit that helps seal it in. Check your vents as well on the transmission. Some have also reduced the oil level in the trans to aid in the problem. But typically the fix involves removal.

Hmmm..... I have two trucks that do this same thing.

X2 with PA, I have repaired many of these. The front input cover will wear usually because your pilot bushing is worn out. Also the expansion plug in the front of trans will leak, the vent in the trans can be defective and yes your trans can be overfilled.

Fill to about a bit under one knuckle down, this WILL stop your leak,

Not if the bolts on the front cover are loose or missing.

Agree with both statements. If the bolts are good and tight, a knuckle low will "cure" a slack input housing. Loose/missing bolts, nothing will change.

The fill a knuckle down is a tip from P.S. mag.

I agree 1 knuckle under for full and open or check the vent

I agree 1 knuckle under for full and open or check the vent

If the vent is pluged, throw it away, once they plug, the rubber swells, you can clean but it WILL plug again real quick

Thanks for the advice. I'll check the vent first and run it a little low for now.

I believe that will fix my problem to. It never leaked a drop until I topped it off.

of course, there is probably a reason spicer wanted 5 qts of oil in it or they would have put the fill plug lower.

I just went through this repair. Replaced my pilot bushing and Input Shaft sleeve and no leaks at all. Originally was puking about a 1/4 cup of fluid when I stopped. You can read my thread here:

Hope it helps.
