Can't get into any gear from a stop once car is warmed up - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Pneub · 04-03-2014, 04:41 PM

So I've been having problems for a little while now. It was always a bit notchy getting into gear even before modifications but it wasn't bad enough to warrant putting anything off. After replacing the clutch, I'd say in the range of 3k miles, I started having trouble getting into gear if the car came to a complete stop. This applied to all gears not just first gear. The only way for me to get into gear was to slide into first as I rolled into the stop and just keep the clutch down until traffic started moving again. If I didn't do that I'd have to slam it into either first or third which then allowed me to get into first no problem. That got old after awhile and because the problem was getting into all gears and not just first (figured it would be a syncro) I decided to replace the clutch. This fixed the problem again for about 2000 miles. Now it's back and I can't figure out what's wrong.

-Car goes into any gear fine when cold. Usually takes about 5-10 minutes of driving after warming up the car for the gears to get sticky. When the car is cold everything is very smooth.
-After the car is warm I can't get into any gear at all. If I do get locked out I can usually slam it into third which then allows me to easily get into first.
-This also applies to reverse.
-Changing the clutch fixes the problem for a couple thousand miles and then the problem returns. I also changed out to a slightly heavier flywheel the second time around.

put stock clutch back in
take it to the dealership

What fluids are you running in the tranny? What have you put in there to try and fix this?

It would be quite difficult to get back to stock considering all the work done

I'm not entirely sure but I do know I've had the differential fluid changed twice now. It made the shifting a lot smoother in all gears but never seemed to have any affect when it came to getting into gear from stock. Evasive Motorsports has done the fluid changes a couple times and they don't seem to understand what is wrong either.

Fluids have a pretty large impact on shift feel and smoothness, I'd probably call your shop and ask what fluids they've been using on the tranny flushes. There might be other fluid options that will give you a much better experience.

I believe the transmission fluid was Motul Gear 300 75w90. I've flushed it twice now.

Tainen · 04-03-2014, 06:43 PM

ok. Then definitely your next choice is to find a good local dealership that doesn't flip too much crap about mods, and take it in.

I don't see that happening. I'm going to have to pay for this to be fixed myself

bleed the clutch hydraulic system and then adjust the clutch master to get the correct throw when hot. You can't engage gears as the clutch plate is dragging.

subiestyle · 04-03-2014, 06:53 PM

it sounds like the modifications are what is causing you problems.

i would bring it to stock levels (can probably leave your current clutch on there now) and see.

I sent this over to Evasive to see if that could be the issue. Thank you.

Thirded.

I agree it's likely the clutch is dragging. A few things could cause this:

1- If the clutch pedal engagement is set too low, then there might not be enough pedal travel to fully separate the plates.
2- Air in the clutch hydraulic system (stated above).
3- faulty clutch (or somehow incorrect model installed).
4- faulty installation.
