Transmission leak.

[Periokid]

I have discovered an oil leak from my transmission. It is coming from the area where the driver's side axle inserts into the transmission.

Eventually I plan on getting a new 5 speed with short gears or a 6 speed but I am not quite ready for that yet (other projects first).

Is there a transmission oil additive that I can use to help stop the leak until I can really fix it right?

Hey David,

How's things? It is the axle seal. I would not recommned any "magic elixer" for this. It will probably have a bad effect on the trans.

I beleive the seal is only a few bucks. You said it is on the drivers side, so you will have to remove that axle shaft and replace the seal.

Based on things you have done already, it should be a few hour job.

HTH,

Larry,

thanks for the reply.

I guess that means the transmission does not need to be removed to do this job?

I'll have to study this a bit more.

I agree that some sort of leak stopping additive would affect the synchros.

Correct. The tranny can stay where it is. Remove the wheel, brake lines,then pop the half shaft out of the tranny/differential. This side of the half shaft has a clip on it to keep it from floating inside the differential. It takes a fair bit of force to overcome it. I used a hydraulic port-a-power and a long screwdriver to get it to "pop." Remember to wear a sturdy glove on your hand to avoid gashes and such. Unbolt your A arm. Then unbolt the shock tower from the body using the 3 nuts in the engine bay. Everything can come out in one big piece as I have done this when removing my tranny. Pluck out the old seal being careful not to score the aluminum. Instal the new seal carefully so as not to bend the metal in the seal. Deforming the seal will affect its usefulness. Use the old seal to bang the new seal in, if possible. Also avoid disturbing the grease installed by the factory on the new seal. Last but not least, reinstall the half shaft being very careful not to damage the seal by dragging the half shaft's splines on the seal edge.

If you have the tools, parts and know how, 3 hours is enough for the backyard mechanic.

David,

I got the crankshaft tool back last evening. Thanks.

Listen, if you will be a while before you tackle the seal job, let me know. Maybe we can hook up. Hopefully things will simmer down next month for me, I have a deadline and hope to be done by early November the latest.

Keep in touch.

Larry,

Glad you got it back. Sorry for the delay. You really got me out of a jam. If you want to hook up I am always willing. I wouldn't mind a helpful hand.

David
