Oil Leak at Transmission Shift Levers

[BCH BRCO]

I have an annoying oil drip from the trans. shift levers. Does anyone have an easy fix for these drips other than pulling the trans and replacing the "o" rings that seal the levers? Any success with an oil stop leak additive?

I have this too. It's the only drip on my rig after the engine swap.

X3........but certainly not the only one!

I believe there is a external seal that can be replaced with out pulling and tearing down the trans. It solved my c 4 leak 5 years ago. Only takes 30 minutes. Assuming we are talking C4 auto trans here.

Worth a try, the seal cost about 3 bucks.

I'm going to assume you're asking about a C4 auto tranny.
The shifter has two shafts, one inside the other.
There is an outer shifter shaft seal in that requires the removal of the pan and valve body so it can be replaced.
Then there is the kick-down shaft that just has an o-ring seal between the end of the shifter shaft and kick down lever. It can be replaced by simply removing the kick-down lever and replacing the o-ring.
You can usually tell which one is inside leaking by looking for the hanging drip.
If the drip is on the kick-down lever, the o-ring is probably the culprit.
If the drip is on the inside shift lever, it shift shaft seal will have to be replaced.
Mine was usually only the o-ring.

Mine has been leaking for years and has been on the to do list.

Ordered the part. Thanks for the info.

Should have said that mine is the standard 3-speed manual trans. that is leaking. Thanks for the info on the auto though....
Anyone with "stop leak" additives for a short term fix?

I don't know about the OP but I was talking about both my 3-spd levers leaking, among other things

Darn! That was one of my better "Rescue Guru" moments!
What's an op?

There's my rescue guru moment! Lol

That was the seal I was talking about as well.

3 speed manual for me. I think the seals that need replacing are internal on the 3.......

X5 on leaking 3-speed at shift rails. Plan to take out and replace seals in the Spring. Stupid Ford!

I know the High Mileage motor oils they've developed in recent years supposedly swell the seals and such to lessen leaks (among other things I'm sure) so maybe there's a similar type trans fluid out there as well?

 

[Blue Bastard]

Those three speeds use gear oil. Any additive you might add should be checked to be yellow metal safe. Some fluids will attack soft metal.

I'm bumping this thread because I'm trying to find those o-rings. Anyone got a place to find them? Link in this thread failed for me.

Assuming 3 speed MANUAL transmission, I would try:

Standard O-ring #111 7/16"ID x 5/8"OD 0.103" Cross Section Nitrile

NPD Part Number : T-7288-2
OIL SEAL, Transmission Shifter Fork Cam and Shaft, O-ring seal,
Seals the shift shafts as they exist the case side
Manufacturer Reference #'s:
Fastenal: 1166823
Ford: 1A-7288-A, E0UZ-7288-A

Note: It appears the O-ring goes in groove on shaft BEFORE shaft is installed in case.
What say @BigOrsnge ?
