transmission fluid change

[Hoppe]

Ok, this should not be that hard but it s my first time. I am changing the transmission fluid on my 84. Removing the drain plug is not a problem, once I switched from my ratchet to a longer torque wrench. Getting to the fill plug is a different option. Porsche engineers should have moved it aft about two inches. Is there a trick to getting my hex socket properly seated? A lot of junk is in the way. I now assume i have to decouple whatever that is the is sliding pack and forth right in front of the plug (throttle?)?

Any advice is appreciated. Thanks.

I used my shorter inch/ft torque wrench ( same size as my standard 3/8 ratchet ) use some anti-seize

I think you can rent one for free at your FLAPS.

Reversible topside oil changer is ideal. Otherwise it is a total PIA.

Had to use a lift in the end to get enough leverage on the filler plug. There's enough room if the car is up high with a flexible joint extension

Let's hope you can remove that fill plug. Next time, always remove the fill plug first to make sure you can. If the fluid drains out and the fill plug can't be removed, you've got a problem.

I actually got smart. When the drain plug was more difficult than I expected, I only did a quarter turn with the torque wrench and then tightened it back before I tried the fill. Finally did something smart.

not my pics but I use this on my gt3 which has access issues due to the cooler. I used on my 89 and worked great

Basically put bit in the fill plug, attach torque extender, attach thin head ratchet or breaker to the extended. You can get a lot of leverage and allows for the odd access angles.

The extender I have is made by Armstrong.

I just did this yesterday on my car. It's an old hotrod so not a lot of stuff around the filler plug but I did have the throttle linkage & clutch cable in the way. I was able to use a 1/2" drive 17mm hex driver but it was tight and hard to get off the plug after breaking the plug loose enough to remove. However I did notice that once the hex head driver is in the plug there appeared to be enough of the hex drive visible to slip a combination wrench onto it right against the filler plug. So perhaps you can try that?

Do you have one of these? It is short enough to get into the small space for the plug on my 83 SC fill plug with a 3/8" socket or breaker bar. Makes it easy to remove the first time and dead easy in the future with regular fluid changes.

I have the hex socket. I used it with an adapter with my ratchet. With the adapter, you could not get in there well with the throttle linkage in the way. I then got a breaker bar that sits lower but the linkage is still preventing movement. I guess I just need to uncouple the linkage and raise the car up a little more so I can get a better position on it. The tools Spyerx posted might actually work best.

Your 84 has a 915 trans, it should not be to difficult to change the oil.
Ive been there / done that myself. ..doing something smart for once

Get this tool, as sold by our host. Just changed my fluid again with it last weekend without even a second thought:

the issue with the plug is leverage. its crowded near the fill plug but you can stuff a hex bit and an adapter in there. 3/4 breaker bar, plenty of muscle for this job. think about it, you always want to have more leverage than you need, its way safer and gets the job done.
i got one at HF. its also a must for the rear axle bolt

[TheSt|G]

New drain/fill plugs go a long way to safety here as well.

The newbie finally got his transmission fluid changed. A hinged breaker bar and jacking the car a little higher were the keys, along with decoupling the throttle linkage (if that is what that was that was in the way). The biggest pain was using the transfer pump. The hose was way to short.

Good job.
