Tranny Leak at Shift Lever Pivot

[Tom Wesenberg]

This is the first time I've seen a leak such as this.
A club member is using gear oil from Bratton's, and I don't know if it has a foaming problem, or why the gear oil reached the shift lever pivot and leaked out.
The color doesn't look normal either, but I don't know what color Bratton's gear oil is.
I suggested he clean it, make sure the vent hole is open, then try another gear oil if it happens again. I use Mobil 626 with no problems.

Good advice as always, but I'm thinking the vent hole also

i had one leak like that because the guy packed insulation all around the floor opening to stop the heat

Strange as it seems, I too have a leak out the top of the shifter, and I know the vent is clear.

And I was told this was the proper oil for it, but I remember removing the shifter top and finding bubbles on the top of the oil, which leads me to believe, this is NOT the proper weight and viscosity for the trans or anywhere else in the drive train Shifter Leak 1.jpgShifter Leak 2.jpgGear Oil.jpg .

I already see your problem right in the picture.. VINTIQUE gear oil. Lol now that's funny
You just made my day thanks

[Ruth]

Hate to be a hater but anything with the name Vintique on it I would be beware of.

[DaWizard]

Mitch, I intentionally got that part of the bottle in the picture just to emphasize that you don't always get what you want or need.

Always glad to bring a smile to your dismal day

This is what Mac's has on the side of their bottle, and other vendors buy it from them... One and a half inches below the fill plug??

Now are we talking trannys or differentials??

I always keep the tranny and rear end right up to the fill plug. I stop filling when it starts to run out the fill plug. I never have problems filling it to the proper level.

[DaWizard]

That has always been the way I was taught. Fill til it runith over.

[BNCHIEF]

That is how i have always done it as well.

[BILL WILLIAMSON]

At least, the shifter will operate smoothly.

I wonder if there is something I can add to the mix to keep the foaming down to a minimum? We used to add STP Oil treatment, but I know that mostly just quiets down the noises. We had a tooth gone from second gear and didn't even notice it. I would hate to put that in and do damage, but this stuff to me ain't even equal to the old 90w gear lube, that was at least like warm honey, this is more like shampoo thickness.

From the owners manual,

"Lubricating the Transmission About once every five thousand miles the gear lubricant should be drained from the transmission by removing the drain plug at bottom of transmission case. The interior of the transmission case should then be thoroughly flushed with kerosene and refilled with fresh gear lubricant. The new lubricant is poured into the transmission through the filler hole, located at the right hand side of the transmission case. Pour sufficient lubricant in until it reaches the level of the filler hole."

Well think about it. The label says the housing should never be more than one third full which is one and one-half inches below the fill plug. Notice it says nothing about transmissions, only differentials. Citing Ford literature. So if you look at your differential where the fill plug is in relation to the bottom of the housing... About one and one-half inches below the fill plug IS THE BOTTOM OF THE DIFFERENTIAL.

Where do they find these people that write these instructions???

[Mitch]

Hey Dennis it's good for business when people FRY their diff's, more gear sets are sold lol

[Mitch]

I use the 600 from Brattons or Tams and never had an issue. No special concoction needed

Makes no difference tranny or differential. Again I quote from the instruction manual,
"Lubricating the Differential
Every 5000 miles the lubricant in the differential should be
drained and the housing flushed with kerosene. New lubricant
should then be added until it reaches the level of the oil filler
hole in the housing."?

What vendor has this label? :p They are in the business of selling parts right?:

[BILL WILLIAMSON]

When filling through the filler openings, HOW IN HELL CAN YOU OVERFILL THEM??????
Minervas' diff was 1 1/2" ABOVE the plug, trans was perfect, never figured that one out????
