Help! Transmission fluid change gone wrong...maybe?
 

Went to do my first transmission fluid change on my new to me 2002 986 5 speed manual this evening.

Took me a while to find the fill plug, and it wasn't exactly what I expected:

I drained the old fluid out of the drain hole. Then went to put the new fluid into this fill hole. Having pumped in a gallon of fluid I'm starting to think this wasn't the right filler hole... :eek:

I decided to reitre from it for the night before I do any more damage, but can anyone here help let me know where I've just pumped a gallon of transmission fluid. And how disastrous this might be? :confused:

That looks sort of like the bolt on the end of the reverse lever inside the transmission.

The fill plug for the 5-speed is in the left-side differential cover, a standard Allen socket and not torx.

Oh dear... :eek:

Something tells me I might be in trouble here with a gallon of transmission fluid where it's not supposed to be? Any ideas on next steps? Or is this a have it towed to an indy shop?

Actually I wonder if I've just filled the crankcase from higher up...maybe draining it from the drain plug again and refilling from the correct hole is all I need to do?

You hope JFP will crawal from bed and point you proper.

Me? I'd be draining everything in that area hoping a gallon came out. I don't think you messed up badly.

Keep us posted. :cheers:

View is from the driver's side, the lower tray removed. 1 is the fill, 2 is the drain; one is a metric Allan head, the other is a metric triple square.

Looks more like a chain tensioner to me.

A normal filler plug looks different.

Good news! I drained out the gallon of fluid I put in. Found the correct fill plug, and filled it with the correct amount of fluid. Put everything back together and it seems fine. Crisis averted hopefully. 🙂 Thanks as always for the amazing help! 🙏

I bought a whole set of triple squares for that very plug. I'll probably never have occasion to use them for anything else.

Out of curiosity, did you originally filles the differential with transmission fluid, then drain it out and put fresh differential (gear) oil? Good catch!

Triple square fasteners show up is various places on different model years, but always a good tool to have around as several OEM's are using them here and there and you never know when you are going to find one in your way at midnight.............

That makes sense, because the amount to fill that MT is not 1 gallon but .53 gallon (US) (2,25 L)
