Hard shifting in multiple gears is almost never a transmission problem. The trans is the victim, not the cause. You can't fix it by fiddling with the trans, any more than you can cure a cold by blowing your nose, even though the symptom might be that your nose runs.

It's a clutch issue. Either the clutch isn't releasing fully, or the pilot bushing / bearing is bad.

Well then what can i fix? I want to go with the same transmission for a bout 5 more months. What most likely can it be? Do you think that by changing the pilot bushing and the bearings fix my problem? -Eric

Do a complete clutch kit, replace the pilot bushing, have the Flywheel resurfaced, and check to make sure your hydraulics aren't leaking or have air in the lines.

What do you mean by resurfacing my flywheel?

I have another question, How hard is it to change the clutch and how? Is there any where in this site that i can find a step by step prosses to remove my clutch? -Eric

Resurfacing the flywheel is what you are supposed to do when you do a clutch job.
You take off the flywheel, take it to a machine shop and they grind it down smooth.

I think the Haynes/Chilton manuals have a pretty good breakdown on how how to do a clutch replacement.

check your slave cylinder for leaks and bleed hydraulics, make sure you have enough fluid. i say this because it's the easiest to check/fix.

I also did something to the transmission that helped me out on the hardness thing that my tranny is giving me now.

When i first got my car about 5 months ago i changed the oil in the tranny, and actually felt a difference. Before it used to be punch it on first when i go into second its already hard. Then i changed the oil, With dextron 3, what a difference i felt. But it has already gotten to me and bothers like crazy that it is still doing the samething, but less. I guess maybe because i changed the oil it might of lubracated the tranny really well and has maybe helped some berings free up a little. I really dont want to go on the headach of taking off the tranny to find out that , that is not the problem. Can you guys give me a 100% thumbs up on that i should change the clutch? -Eric

this is a 5spd right..... and you used dextorn 3...... lol. no offense your spouse to use gear lube in a t-5. cause tranny fluid will barke down faster. and know you have to get alll of the crap out of thier.... all of it... then put gear lube in it like 90-80 something liek that have fun

The T5 uses ATF, not 90 weight. Back in the days of V8 Vegas we put 5 speeds out of V8 Monzas in them--some had 90 weight from the factory and some had ATF--they looked identical on the outside. The word from GM was to never replace ATF with 90 weight--if the tranny was broken in with ATF run it with ATF--same for the T5.

You are so wrong , i had previously posted up on what oil to use on my t5 , and what was best. They told me that using dextron 3 is the best. You are wrong. As a matter of fact my tranny hasent gotten worse or bad . Since the day that i put dextron 3 my tranny has gotten a better feal every day. especially the first month. -Eric

Like RB said, it's likely clutch-related(fork, bearing, bushing, pressure plate, etc.), so I doubt you'll solve the problem without dropping the tranny. And since you've already changed your slave cylinder(assuming it was bled properly, and it's not leaking), you know your hydraulics are fine. But beware! One powerful shift could blow your new slave cylinder(ask me how I know, lol), so you better fix the problem soon.

As for the current debate, the T-5 uses ATF(supposedly because the thinner lubricant provides better cold weather performance), though I've used gear oil too, and it made no difference(maybe because I live in a hot weather climate--Southern California). But there's actually a little metal tag hanging on my T-5 that says "GM 5W-30."

You really have blown one of those slave cylinders? Wow. But then again those things are plastics. I think i did bleed it right ever scence i got it , It does scratch or make to much noise going into reverse.

You're kinda right. Non World Class T-5's use regular gear oil. Worls Class T-5's use ATF because of the different parts used (I think the neddle bearings, but not 100% sure on that) they are simmilar to materials used in automatic trans which are not compatible with regular gear oil, or something like that. Your T-5 will have a tag on it telling you what to use. If it's a world class T-5 it will say ATF.
