Fighting with my transmission fill plug…

[Matt Monson]

If the car was shifting fine and not making any noises I wouldn’t worry about it. Just change it every few years or every 10k mi going forward and you’ll be fine.

Expect the Swepco to shift slowly when cold. While I recommend it for race cars, on the street I prefer good old Walmart Supertech brand conventional oil for daily use. …leaves thread now that all the Kendall fanbois are triggered.

Unless you find some unusual amount of stuff in your old oil, not sure it will do much good to do a short interval oil change. No harm though.

Is oil analysis a thing for transmissions? I guess it could make sense, but I’ve always thought that the quality of the shifting and perhaps a peek at the R&P tells you most of what you need to know.

It’s not exactly cold here on the gulf coast, it’s 90 degrees at 10 am, but figured a bit of heat wouldn’t hurt getting as much of the old oil drained as possible. I used an aluminum tube to connect my heat gun to the fill port and turned it on, warm air starts coming out the drain hole. Sure enough after a minute there is a dribble of additional oil coming out. Not a lot, it’s probably inconsequential, but it was worth a shot.

Using camera scope I take a peak inside, can’t tell a damn thing from the drain plug but looking through the fill I can in fact see a gear and it doesn’t seem to be missing anything major.



When I bought this 911SC two years ago I hadn’t driving a manual regularly in a few years. It took me some getting used to but now I like it quite a bit. It’s a bit balky going into first while moving but I have learned how to finesse it. Occasionally it doesn’t want to go into reverse but that can usually be finessed as well. Overall it seems like normal a normal 915.

Congratulations, now I can uncross my fingers! What a journey.

Thanks… I used my heat gun to blow air through it for a while this morning and got a last little bit out before cleaning up the plug areas a bit and refilling. The new plugs are torqued to spec after applying some never seize to the threads. Having said that I’m gonna be looking for some of the old style plugs per John Walkers suggestion. My current thinking is I will drive it for a few months with this Swepco and then replace it again.



In any case I’m waiting on stuff to come in to finish my distributor rebuild and I should be getting my 996 back in a few days from its big IMS and clutch replacement. The 996 has much better air conditioning which is important as the temps here are in the mid 90s with high humidity.

There’s really no need to change it twice. Spend the time going for a nice drive, and spend the money buying your wife a nice lunch.

Matt: Are you recommending Supertech, GL5 gear oil. Rob

I am. Haven’t needed any in a while but it used to be in red 1qt squeeze bottles.

Kendall NS-MP of the often times contentious PPTF Kendall vs Swepco "controversy" is next on my list as well. If you do both, you can then add another anecdote to the lore. I believe truck oil works too.

Meanwhile, you can tell everyone how you once spent a weekend freezing a nut off

Talking with the PO right now at work and he hadn’t changed it in the decade-ish he had owned it. It shifted and worked just fine with whatever old oil was in it. My new found Indy mechanic has been working on Porsches for 40 years and insists on Swepco so that’s what I’m going with.

But yeah… had to get some dry ice to bust a nut
