DIY: Manual Tranny and Diff Fluid Change
#91
The supplies listed above worked fine, just finished it over the weekend. I highly recommend purchasing the Hand Pump, it made the refilling a cinch.
Also, wipe the threads on the rear diff drain plug hole before inserting the plug back in, they'll be filthy too.
Like others mentioned the MTF fluid in the car looked ok, this was just preventative maintenance. The car has 60K miles on it. I bought it used at around 47K, so I have no record of previous maintenance. After the fluid change, it shifted about the same.
The diff was a little dirty, and my plug had that paste on it, too.
I also reused the 2 metal gaskets on the MTF and Rear diff plugs, no issues.
here's some pix.

I apologize for resurrecting an older thread but this is a very good one and I have a dumb question about whether the trans fluid level on a 6mt should be checked hot or cold.
Had my 6mt fluid changed by a non-Infiniti shop and can't shift into 2nd when cold. Decided to replace the fluid with MTF from the dealer myself and am following these instructions in this thread. What surprised me is when I removed the FILL plug first, 22 ounces of fluid immediately came pouring out of the FILL plug (I measured it after).
Now I had warmed up the tranny by driving about 15 miles to make sure the fluid was warm and would drain out good. So my question is this: how much does the fluid level increase when the trans is warm? Or did the service place over-fill it? The Infiniti maintenance manual says overfilling the trans can make it hard to shift.... maybe this is the problem rather than the kind of fluid??
If I fill the trans tomorrow morning to the bottom of the fill plug cold, then will the trans be under-filled?

They must have filled it up with the car on an incline and put all 4 quarts in.
Capacity is around 3.25 quarts. You have to pour it in cold, right to the bottom of the fill plug. Makes sure the car is level. .
If you do with the car level, should be impossible to over fill. Just fill it till it hits the bottom of the fill plug, and you're good. No need to drive the car and let it warm up and check again.
If the car is level, and it comes to just barely touch the fill hole, you're good.
You probably don't even need to change it, you just needed to let that extra ~.75 quarts out. SHould be fine now.

Thanks for the info!! The total amount that drained out overnight was 3qts and 22oz so I think it was definitely overfilled.
It took 3qts and 9oz to fill it up to the fill plug, car level and all.
Shifts a lot smoother but the real test will come when it's set out overnight on a cold night. I'll leave it out tonight and post the final results after I drive it cold. Kind of wish I had tried just letting the excess fluid out first but I already drained the whole thing by the time I saw the reply.
Thanks
