Tranny fluid level

[robotman]

I have a standard 1975 911 with a tranny leak i am going to drain it and refill with synthetic 80w-90, do i fill until it just starts coming out the fill hole?
I guess i need some kind of pump also?

That is correct, fill until it starts coming out BUT first......


Please be sure that you can remove the fill plug before draining it.

Several of us have had good luck refilling without a pump but it IS a good excuse to buy a new tool.

Forgot to ask. Do you know where it is leaking? These transmissions respond well to Swepco fluid. I belive the consensus here is that is the best fluid to use in a 915 box.

Not sure yet but i think it is the case. Does using swepco help stop leaks and why?

Swepco won't stop leaks but it will help improve the shifting.

The reason I asked about where it leaks from is that some leaks are repairable with the trans in the car.

On the bottom there is a plate with 4 bolts that tends to leak. A paper gasket is all that is needed here.

Also, the shift rod seal is known to leak and that is accessible from the rear access panel. It isn't an easy job but doable with patience.

I didn't mean to sidetrack you from your project.

Thats good info and i am hoping i can take care if it with the trany in the car.


Thanks
