Transmission Issue After Track Day

SPOHN · 11-27-2011, 05:32 PM

Well guys I just for done with a two day track weekend. Well on my last session of the day I was having problems with downshifting into third. It was grinding bad and would not go into gear. I would hold the clutch in threw the turn then reapply into third with better success. This happened a couple of laps.

Well when the run was over and I went to exit the course up the ramp in second gear it wouldn't go in. I had to stop. It would go into first this time. I had to slightly rev the motor and force it into gear. It hardly went in but got me back to the paddock. When there and stopped it wouldn't go into any gear at all. I tried every thing.

After letting it sit there for for five minutes it started to let some of the gears come back but hardly. Eventually with time the gears came back but not second. Second would go in hardly but when you released the clutch it would just grind and throw itself out. I decided I'd limp it home without second. On the way I got into some traffic and all the gears started to get a tad smoother. Even second. But still very much notchy. I did some downshifting and it doesn't play nice with doing that. Very notchy than standered shifting. Every gear is the same. Still notchy its like there something keeping it from sliding in. You can feel three different levels of resistance per each gear before it falls into place. I will be taking it to the dealer tomorrow. Also guys I don't have SRS and I had just put Redline fluid in it two weeks ago.

Clutch got a tad warm?

Skeeterbop · 11-27-2011, 05:52 PM

interested to hear what they say. Was this out at Road Atlanta?

Red__Zed · 11-27-2011, 06:06 PM

Most likely boiled your clutch fluid. If it keeps acting up, bleed the lines...probably have some air bubbles.

Could also be clutch slip related, might have glazed the disk. Is it slipping?

SPOHN · 11-27-2011, 07:01 PM

Could be all the above. Clutch pedal feels great even now and then. The fluid seemed fine and wasn't boiling. I do have a SS line with Motul fluid also. The clutch isn't slipping at all. Seems perfect. Now the manual doesn't seem to want to move all the way over to even attempt to go in first and second. What is the shifter plate that I've heard people mention?

Chris,

you may need to pull the transmission and check the actual clutch plate... your still on the OEM clutch right? may want to go ahead and just upgrade to a new one.

Mike · 11-27-2011, 07:47 PM

Sorry to hear that. I wondered why you were leaving when I was coming back from the gas station. If your fluid was boiled, that would be easy enough to bleed and see if it still acts up. At that point, if it does, I would just pull the track numbers off and take it to the dealer.

SPOHN · 11-27-2011, 07:53 PM

If the dealer drops it I'm defiantly going to slap another in there. The clutch might be some issues but I feel theres something else that's the main culprit. We will see.

Im planning on taking it first thing in the morning. I'll see what they say before they get involved. I just looked at the fluid and it's green. Was red.

Course our clutch line runs right near our cats and or test pipes. I do have it wrapped though.

I know you will, but please do keep us updated. May help me decide on whether or not I chose to replace just the flywheel or do a bit more.

Also, how many miles are on your car? Just curious how much distance has been put on it.

SPOHN · 11-27-2011, 09:31 PM

If your going to do the flywheel I would do the clutch also.

My car has 8k miles on it. This was my third track day on it. But my first day wasn't as abusive as the last two days. But beside those days it hasn't been beat up on much.

cossie1600 · 11-28-2011, 08:37 AM

A cheap way would be to start changing the transmission fluid...

SPOHN · 11-28-2011, 11:17 AM

Im going to wait till this weekend before I take the car in. I'm going to bleed the clutch and I have to remove my track numbers. It's been raining all day so I might as well wait. No big deal. Plus I want give my car an inspection being after a track day. I'm about to change all the fluids out. I'll keep you guys informed.

VQStryker · 11-28-2011, 04:05 PM

Watching for the outcome. goodluck spohn
