Hey guys,
New to the MR2 world. I have an 01 with the 2ZZ/C60 swap. As a habit I always change all the fluids in cars I buy. On mine I changed the transmission fluid and now I seem to be running into some issues.

• When in lift in 1st I press the clutch in to put it into second and it’s like the clutch doesn’t exist. RPMs fall as if I hadn’t pressed the clutch in at all. But it shifts normally through first and into second when not in the high RPMs.
• When down shifting into 4th (and rev matching) clutch fully depressed she ‘clunks’ into it. As if the clutch weren’t fully depressed it almost grinds however when upshifting into 4th there’s no unusual noises or feeling.
• Fearing I may not have put enough fluid in I opened the “speedo cap”(?) (pictured) the fluid was over flowing. For reference I scoured this site and found the recommended fill of ~2.4 qts. I also Used Valvoline Synchromesh MTF.

I know it’s difficult to asses an issue over text but any help with probable issues/causes would be greatly appreciated.

Side note: fairly certain my throw out bearing is going out. She chirps on and off while the clutch isn’t depressed. I’ve tried the white lithium grease trick several times to no avail. So I’m assuming I’ll have to remove the transmission regardless.

Sounds like a clutch issue - like the friction disc is sticking to the input shaft splines a bit. Has it been done recently?

It was done before I got it. It has a “4 puck sprung hub clutch with a chromoly flywheel” per the previous owner.

2.4 quart of oil inside the transmission is way too much.
Too much oil inside the trans > too much pressure inside the trans.
Drain all oil again, then refil with the correct quantity : 2.2 quart or 2 quart.
To give help : when refilling the gearbox with the correct oil quantity, oil should not be level to the “speedo cap”.
If it's the case > the car is not on flat road, the back of the car is lower than the front and/or the oil has not been fully drained.

Thanks for the advice. Noted not to trust all the info I’ve seen on here. I’ll be doing this tomorrow with just two quarts and giving an update. Thanks for the help.

When full the transmission fluid should come up to the level of the -upper- hex key bolt. Make sure you drain from the lower bolt. Speedo hold should not be involved at all.

do you have a pic of what you’re talking about?

This is the documentation I found:

DIY Manual Transmission Fluid Change

This is a guide to help you with your manual transmission fluid change, It doesn't cover automatic transmissions in which different steps, parts, and tools are required. Notes: I am doing this on my XRS with a C60 6-Speed Manual Transmission (same as the Matrix XRS and Celica GT-S). For the...

Thanks! I’ve seen many people use the “speedo cap” as an easy way to fill without the use of additional tubing/oil pump. But serves me right for not at least opening the fill plug to ensure I stopped when I saw oil coming out.

Update:

Removed the fill plug and Funnyman was on the money🤦🏻‍♂️ an excess amount of fluid came out. .5 qts give or take. Hopefully my idiocy didn’t cause too much damage. I’ll be replacing my trans fluid tomorrow and give an update (if any) on its shifting discrepancies.
