I have an 05 XT 5 speed and I bought it used with 16000 miles in 07. When I checked the trans fluid I noticed it was on the low side. I checked with dealer and he sold me the Motul 75/90 fluid I use to top up . I notice every 5000 to 10,000 miles the fluid is always back at the low side. What is up with that? Car has 40,000 miles now and at 30,000 I made them change the MT fluid because it was extremely stiff during cold weather. They put the STI fluid in was what they recommended . I checked it after that and it did not use for a long time . Now at 40,000 it was below the low mark . Any thoughts? Is this normal?

I know a this is a basic question, but are you checking after letting it sit for a couple of hours and on a level surface?

Did they replace the crush washer? If not, you could have a leak.

Unless theres a leak I can't imagine any way it could be losing fluid.

Cmon now I can not be the only one that has this issue! Level driveway, Any fluids are checked 12 to 24 hours after last use of car . NO leaks underneath from plug. I have had to add at least 1/2 bottle of the MT fluid in the last 24,000 miles and that is 4 or 5 times it has been on the low mark.

Your neighbor is stealing your Motul lube a couple cc's at a time

Difference may be caused by installing fluid in warm trans, and checking fluid in cold trans. The expansion range may be enough to cause a gap. It does for oil and ATF, so probably trans oil as well.

good luck

Start looking for a leak.

There is no way the 5MT could consume fluid. It HAS to be leaking from somewhere. That somewhere could be through the input shaft seal into the bellhousing, which is a difficult one to find. It usually manifests itself in a slipping clutch and lots of smell.

Look at the axle shaft seals, that's where I had a similar leak a little while ago. Do you get a smell whenever you stop at a red light??
