Help I think I injured my tranny!! Weird problem!

Hey guys, tonight I wemt for a joy ride with my buddy and we were out on a sticky back road launching the car and logging some datamaster runs...

Well after a couple launches we drove around for a half hour and came back to do a few more runs...

This time my first launch i went to go into second and either missed second or it just wouldn't go into gear because I then slowed down and went to go into third but it wouldnt go, it wouldnt go into any gears while the car was running...

I then turned the car off and it went into every gear just fine... so I turned the car back on in neutral and tried to put it in first but i couldnt even force it to go...

I then decided to put it in first with the car off and then start it, but when i turned it over it started to try to actually pull the car.

I just could not get it in gear any other way so i put it in first and gave it gas while starting it and it still pushed it but i got it started.
once it was started in gear and rolling the issue went away and it went through the gears just fine...

What the heck did I do that it wouldnt go into gear?? Also would you continue driving the car since the issue is gone or do I need to pull this tranny out (which I hate doing lol)?

Sounds like a clutch problem. (maybe master and slave cyl...)

defenitly a clutch problem. especially with you launching it like you said, somethings happened where it will not disengage. This is shown when you put it in gear, then tried cranking the car....the pedal was down, but the clutch was still engaged, hence the movement. I hate to tell you bro, but you probably WILL be pulling your trans to fix this problem. Bright side of that is, racing clutch here i come!! :D Otherwise before pulling it, check your lines and cylinders (as shoebox mentioned) to see whats happening. Good luck.

Well the reason I am not excited about taking it out is that I already have a Spec stage 3 that I installed a couple years ago and only put about 5k miles on...

I am going to attempt to get under there and check all the lines and master/slave cylinders, is there anything specific I should look for. Also should I attempt to flush/bleed the system or no?
