Clutch Replaced

[StOpNG0x]

I had my clutch replaced today by Toyota and after I picked it up and drove it home I noticed a few things I wasn't used to. I'm not sure if what I am going to describe is normal operation after a clutch replacement or something I should be concerned about...

When I shift into different gears I can hear and feel the gears changing as I shift. Specifically, below my right forearm as I shift I kept feeling a faint noise like something was hitting the armrest underneath my arm. I had never felt or heard anything prior to the replacement and prior to repair it was smooth shifting through all gears. Do I need to allow the car to go through a break-in period?

Also, as the car was idling the RPMS would bounce from the idle point of 600 RPMS then up to 7-800 RPMs and then dip down to 480 RPMS and back to 600 RPMS every 15 seconds or so - the AC was on. When I have the AC off it holds at 600 RPMS which is normal from previous operation. The RPM fluctuations would happen every now and again before when my AC was on, but it has me concerned as I just picked up the car up and I'm experiencing these different things.

Should I give it a fee days for the car to adjust to the new clutch? I'm not tech savy enough to know if that has anything to do with it, but any feedback is appreciated.

The car has about 53500 miles - 2013.

Thanks.

When doing a clutch job they typically drain the trans fluid and refill it after. Changing it from factory fill changes the shift feel and gearbox sound, maybe because it's a bit slicker.

RPM fluctuations are normal even if A/C isn't on it will fluctuate if you roll both windows down for instance.

Oh, I'd give it a few miles for the car to get used to the new clutch and for you to get used to the new clutch.

Why do you figure your old clutch went out .. ?? Boosted, tracked, new driver, don't know ....??

500 mile break in period on any new clutch that ive ever seen. Its normal to smell a little burn on the initial few miles. Its gonna be a lot more notchy shifting especially is they used some rlly gewd trans fluids. Also Rpms sound normal for me with the AC on. Try cranking the ac fan to full with the temp on lo and see if it dips alot less. Not sure what if any sensor has to be removed when doing the job but I know i had a clutch job on a FWD car that has some sensors removed and they forgot to hook one back up. That threw a CEL though so its probably nothing to worry about.

I hope this is a serious question and ur not trollin because im about to answer it lol. The drive shaft has to come out first so trans fluid will pour out of that end and then you got a mess.

One of the throwout bearings went and it happened to be covered under warranty. They said it wouldn't be a bad idea to just replace the entire clutch since everything has to come out just to replace the bearings. I said why not and all I paid for was parts instead of getting charged $1500 with labor all I paid was $587 including tax.

Man, they did you a solid. Some people here are being told the TOB is a wear item. :/

Just curious as to what happens when the tob fails

They don't go all at once. First they get noisy and if you're in tune with it, you'll feel it rumble in the pedal.

They screech when they start seizing. Don't wait that long.

I have determined my idle noise is the flywheel chattering because it goes away when car heats up or clutch pedal is depressed. Guess if something brakes we will know then LOL

Oh,.... well, I'll be darned ........ ol @tofurun learnt me something today ......

I didn't realize the tail shaft had to come out of the transmission on the FR-S.

I'm stuck in the 50's again ...... We used to take apart the universal joint and then drop the driveshaft. Or, at least I did ...... yep, those "C" clips were a butch to get off of the universal joint without messing them up .....

Thanks again fer the edumacation. I'm going to add you to my consulting staff, along with @Ultramaroon.

No, that's called "neutral rollover." It's the freewheeling gears rattling around in the transmission. Nothing to worry about. I've driven/worked on many friends' 86s. They all do it.

Stock lube does a better job of hiding it at the expense of being tougher to shift when cold.

When did I get promoted? You said it was an unpaid internship.

Yea I noticed it after one piece drive shaft and stupid expensive motul fluid.
