Default T56 issues Again!!!!

So I was driving home from my friends Party in Akron This Saturday (an hour long drive) and my Trans went nuts! I was getting on the hwy on ramp and shifted from 3rd to fourth and the shifter felt tight as hell and I had to literally slam in into gear!

Then I proceed to up shift and it will not go in to any gear and is Stuck in neutral as if the whole trans is binded up! I managed to get her home crusin in sixth gear after wrestling with the shifter. After i got off the highway it was extremely hard to shift it into any of the gears except for 3rd as it would not go in at all!!! I get the car home and let it sit for the night.

The next morning it it was totaly fine! WTF is up here, is it toast? Thanks for the Help. I checked the Trans fluid and its fine and full. The clutch fluid is still a little black even after the flush but didnt smell burnt. I cant figure out whats causing this? A bent shift fork?

Sounds like hydraulic issues to me. The dark fluid you described most likely has a lot of air in it and the heat from the drive home just made it that much worse. I'd try bleeding the hell out and see how it is after that.

hydraulic issues would cause the feeling in the stick to change? I just thought that would affect clutch pedal pressure? Correct me if i am wrong please lol. Thanks

Hydraulic issues would make it very hard or impossible to get into gear cause the clutch isn't releasing all the way. The clutch pedal will probably feel a little spongy too but it will definitely affect your shifting.

It sounds to me like it could be a hydraulic issue to me also, just had this happen to me in my commuter car a cellica. It ended up being a master cyclinder for the clutch but i experianced similar issues while trying to shift. Did your clutch seem to work normally? When happened to me, I could feel a difference in the pedal while starting. If it was not disengaging then it would cause it to be hard to get into gear; unless the rpm is at the right for the next gear.

I had a slave go out on my Wrangler that I used to 4wheel and it wouldnt shift, however It didnt feel like this does. It was still smooth in the neutral position.


Update
On my camaro Its like a rumbling grinding feeling in the stick when in neutral and you cant move it into gear unless you smack the **** out of the shifter. It also doesnt wiggle side to side like a manual usually does when in neutral and return to center it just flops into the position between 1st and 2nd. The clutch pedal feels very firm. Is this still a possible hydraulic issue? thanks for the Ideas guys I really appreciate it!

First things first, don't force it into gear if it doesn't want to go. You're just going to damage your transmission that way. Can you put it in any gears with the car off?

Personaly I think that it is your hydos for your clutch. If something was f'ed up with your trans it would do it all the time, thats what happened to me when I blew up my syncros. Your slave line might have gotten to hot since your drove it for an hour and gotten air bubbles in it and made it hard to shift. Are all are the gears hard to get into when the car is off. When the car is off not all the collars will line up correctly.

Few questions: Do you have headers? What year is your is your car?

Oh and normaly draining the trany fluid you wont see any metal since the T56 has I think 2 magnets inside of it.

MY car is an 02 and has kooks long tubes. The wierd thing is that earlier in the day I had just installed a energy suspensions trans mount though I cant see how that would be related. All the gears were hard to get into and it would not go into 3rd at all. The next morning I went out and it was still really tight and wouldnt go into thrid, so I went along working on my Winter car.
After I was done with the eclipse I hopped back in the camaro towards the afternoon to see what was up and without starting it the shifter moved freely in neutral like it should and shifted into any gear just fine except for 5th and Previous to this I was having an issue with it popping out of 5th and grinding under normal acceleration. I figured that the 5th syncro was going and that it was no biggie. Im at a loss. I drove it to the body shop today to get he door fixed from a recent break in and it shifted fine the whole way there minus going into 5th gear as usual. I just dont get it, This car is tempermental lol.

I have already ordered a new slave cylinder with the LS-7 clutch kit I Ordered so that will be replaced. Should I change the master too you think? or will it be ok with just a good flushing out and the drill mod?

Thanks for the advice!

I'd replace the master, too. I just got done swapping out my tranny, clutch and slave but for some reason I skimped on the master. Now I'm kicking myself in the *** cause I've got to get under the car again.

yep looks like I'll be adding that to the list now. Honestly Im about to say hell with it and contact tick performance and send the m6 in and get it beefed up while its out. I might as well I guess. I had the line on a built t56 locally but the guy is now having second thoughts on the deal and is giving me the run around! Thanks for the help guys.

Most of the time , when you have an issue like yours , its clutch related . In your situation , I would agree that its a hydraulic issue . Replace the upper and lower units for best results . When you have the transmission out of the car , inspect the tip of the input shaft for wear as this is a good indicator that the pilot bearing might need to be replaced as well . Even if you do not replace it , dab a little grease inside it if you can reach it . I usually use a ice cream stick with a pea size dab of wheel bearing grease .

Since you have long tubes they can heat up the line going to the slave and bubble up the fluid if it isnt wraped. But since you got a new clutch inspect your old clutch and see if anything was wrong. I wouldnt want you to get the trany up there to find out it is your trany that is screwed up. It would bother me not haveing 5th gear, so personaly I would just sent the whole thing out and get it built up. Sorry to hear about all your bad luck with the car.

Im sending the Transmission to Tick for the Stage 2 build up plus whatever else it may need! I might as well do it all in one shot while I have the money available and the Transmission out! Wish me luck. I'll be pulling the trans out on Thursday so any advice is much appreciated. I will be using the write up on install university as a guide!

Well you are changing out everything so you "shouldnt" have anymore problems. Make sure you get the car real high if you dont have a lift. When your pulling the trans get a friend to help. Invest in I think a 13mm and 15mm socket with the U join on it (its tight up top). Make sure you have plenty of extentions too. And you cant re use stock GM PP and Fly bolts (but you can re-use ARP, that what I have). Oh and if your not getting a new fly make sure to get it resurfaced. Other then that good luck, you are going to have a blast getting this transmission out.
