Question about transmission fluid overfill
 

Hey guys, I finally got around to chaning out my stock tranny fluid with Redline. I was stupid and parked the car at at incline, so I ended up filling the tranny with all 2 quarts of fluid. I think it should only be 1.8 quarts, so my question is "are there any problems with overfilling the transmission by .2 quarts?" I tried searching for this, but nothing came up. Thanks in advance.

BTW, I took the car out for a test drive and it shifts really smoothly. My first "performance mod" on my baby and it's well worth it.

Dave...I filled mine with the car level on four ramps and it took two quarts of Redline. Nothing came out the filler hole and that's the indication of full. Been 5/6 weeks, no dramas. Forget about it, it's okay.

Mine took the full two as well. It's been changed twice now, and it was 2 each time with none leftover. Nothing to worry about.

I just did mine this weekend as well (Red Line rocks!) - it was within an ounce of taking both quarts when mine started to dribble out... I would agree you're fine.

BTW, for those of you who've used Red Line in your tranny before- I swore when I did my Miata the oil was bright red... but I think I may have used MTL instead of MT90... am I remembering it wrong? I was surprised to see the MT90 I put in the tranny was yellow, like the diff oil.

same here. i was a little worried, but it's been over a month now with no worries

Whew, thanks guys. Now I won't be as paranoid driving my 8 around. Oh, just one more thing, I was just curious as to what torque setting everyone torqued their filler and drain bolts to? I followed the DIY from Omicron's thread, http://www.5cats.org/rx8/trans_diff_refill/ , but the torque said 27-48 N-m, so I just set it to 35 (split the difference). Just curious, that's all.

I also used that page for reference... I set the torque wrench to 45 N-m or so. I was really surprised how easy they were to remove from the factory... my Miata's were all on much, much tighter.

Ditto here. I pumped in two quarts of redline, and I was worried so I lowered the car to be level to see if anything came out..........and ........ nothing came out. It has been shifting great for 3 weeks with the Redline, all two Quarts of it.

Yeah, they weren't very tight. I just nipped them back up using a ring spanner.....

Well...here is an update...sorta :)

I just swapped out my rear differential fluid and I wasn't able to access the fill plug as easily as I thought I could. I ended up not using my torque wrench and just winging it with a regular socket wrench with a socket extension.

Yeah- it's a bit of a funky angle to get to the fill plug... mine just barely fit.
