Too much gear oil

I have an ax-5 transmission. Why would there be 6 quarts of gear oil in it? How will this affect it?

Did you remove the filler plug on the passenger side of the transmission BEFORE you drained it from the bottom? Six quarts doesn't sound right for an ax-5

Strange. I thought maybe it was somehow overfilled above the fill hole but if you loosened it and it didn't run out that theory is shot. Just for yucks........using the 6 qts you drained out why not fill it to the fill hole level and see if it all goes back in. Definitely a ax-5 right? Just asking

Yeah its a ax-5 and I will say i didn't pull the plug all the way out. Just loosened it to make sure I could get it removed before I drained all my fluid.

yeah those AX5's only call for 3.3 liters according to ALLDATA. just a heads up guys, if you need to know a fluid level or something spec wise I can access it for you. just give me a heads up and i'll get it to you. hope this helps.

I'm not even close to pro but I would refill it with the old fluid just to see how much goes in up to the fill level. I still think 3 1/2 quarts should fill it to there and no more. I just know what I have read not years of experience.

87, your right it does call for 3.5 im just going by alldata specs. either way once you fill up to the fill drain hole thats as much as will go in it. some people for some unknown reason take the shift tower off and fill it from there but then that over fills the tranny and tears up sycros and gears...because when you think about it 6 quarts would fill the whole transmission up if you filled it from the shift tower. just my $0.02

If you overfill it I dont really see any harm coming from it. I might be wrong, but I dont think I am. With other things you will blow seals, like pinion seals on diffs, or all type of other seals if you put to much oil in your motor. With a transmission though it cant build pressure to blow a seal since where the shifter goes in it is not air tight. The worse I could think might happen is that you lose a bunch of oil through the input seal and it contaminates your clutch, even that is a stretch. When you replace the fluid I doubt it will have any problems. Whoever filled it probably filled it by removing the shifter and filling through there without removing the fill plug to make sure they didnt over fill it.

Sounds like bigger minds than mine agree it might have been overfilled. But because it sounds like it has been running on 6 for a while it doesn't seem to have hurt. Refill with new and enjoy the day.
