Hard to shift when car is hot. Can I get a trans guru in here?

[707]

almost sounds like the disk isnt fully disengauging from the flywheel/pressure plate. Look inside the trans viewing port and move the TOBF up and down with your hand. If it moves freely and you you a clanking sound its quite possible the input shaft sleeve bearing is broken... Ive broken 2 of those fkn things... and I have no idea how I did it...

Its not broken.

Ive broken one myself and know how it feels. His car shifts GREAT any other time except for reverse when warm. And its random. Sometimes it will go right in, sometimes it will lock you out and you can feel the car rock as you attempt to get it in gear.

That's exactly what my car was doing two summers ago. The hotter it was out side the worse it was. When I tried to shove the shifter in gear the car would start moving as if I wasn't pressing the clutch pedal at all. I did the SS line and never had the problem again.

I've checked in there with a mechanics mirror and a flashlight before and I had a friend actuate the clutch, everything looked 100% normal!

Yep! If you're moving it's awesome, if you're stopped, you're F^*&ed. Lol

Sounds like that may be my problem! I just don't know why it happens on some cars and not others, it makes no sense.

time to pull the gear set.

I'd put my money on synchro/blocker ring & slider ring.

What would cause them to break? Just regular use?

[bitts]

I wouldnt say broken, just worn out from not being aligned correctly.

Put the car up on jacks stands and put the car in gear then turn the car on, tires probably wont move but u might hear a whining sound from the trans.

Hmm, I'll have to try that and see what happens. Does it matter what gear? I'm assuming Reverse.

Well his car does drive so I would imagine if he starts the car while in gear the wheels will spin

I thought maybe he meant keep the clutch in.. I'm not sure.

To clarify though, the car drives totally fine and shifts great when it's moving.

Oh OK, not to discredit what bitts said but if it was your synchros I feel that you would have issues with shifting while moving too. I say you do the line either way. If it fixes the problem than great, if not its still a good upgrade to have.

Put up in jacks stands put it the gear that's giving your problems then turn on.

My friends car worked fine but there was no reverse at all.

Its a shot to try.

Yep just have to measure and see how long of a line I need!

My car does the exact same thing. Used to do it on hot days when I drove it to work more often. Now Ive only noticed it after a lot of runs at the track. When it starts to do it for me I adjust the clutch peddle so that it pushes the master cylinder push rod in a hair further. Fixes the issue for me. I agree it's probably the factory hydraulic lines. I've meant to install the SS line but haven't done it yet. IMO the clutch is not fully disengaged because the hydraulic system isn't pushing the fork far enough. You may have seen it move but did it move enough to disengage the clutch? When this issue happens to me the car pulls forward when I have the clutch peddle to the floor with the car in gear. When I adjust the peddle to push in further the issue goes away. I also have a HDSS but I used a stock fork (regret that decision). It may have something to do with the extra load required to disengage the aftermarket clutch wearing my stock fork at an abnormally fast rate?

I only drive my car about 4k miles a year so the issue might come up once a year. I'm curious to see what solves this issue.
