last night was my first night at the strip with the new ACT installed. I had zero wheel hop but did miss a few gears due to it not wanting to go in at upper RPMs in 3rd gear(has been like this ever since the ACT install.). any ideas why my clutch wouldn't allow me to shift at 7500?


listining today...i have a new "whine" type noise coming from the tranny or transfer case. Its almost a very minor grind, but it makes a whine noise(not like standard decel tranny whine). It only makes the noise with the clutch pedal out(not on the floor).

Any ideas what this could be?

i fear its something in the transmission...but i guess it could be transfer case related...but, i thought a transfer case would either let go, or work....not sure if they get whiney.

thanks in advance

 

Try adjusting the pedal, it might not be adjusted properly for it to engage. As far as the whine, its possible it might be the TC, was the right fluid put in the tc after the install?

 

god i hope they put fluid in there. Im almost positive he did.

 

If the tc was filled up with the wrong fluid, most likely the ring and pinion on the tc is focked! BUT, it could be something else with the clutch. Find out what was used

 

well, i watched the guy use a 5gal bucket and pump to fill it up....well, the tranny and the TC. i figured it was diaqueen.

BUT, the service manager told me they put synchromesh in the tranny, which was BS...because its red and the stuff they put in was clear/oily color. And i watched him put the same thing in them both.

And also, the clutch was installed about a month ago....i owuld think if the wrong stuff was put in, it would have shown its ugly face a while back.

 

who installed it? ? If they ****ed it up u need to take it back to them and have them fix it

 

"they" are out to get "us"

 

OK, this morning on the way to work, the whining seemed to be worse....and it does it whether the clutch pedal is pushed in or not. It gets louder the faster i accelerate, or the higher the RPM.

The sound ALMOST sounds like riding beside a big truck with mud tires on. Hard to explain, i guess ill have to drive an hour to mitsu and have them solve it. As badly as i don't want to, i feel like they will just mess something else up.

 

If you saw them put the same fluid in your T case as the transmission, then you are in trouble. Was this at a Mitsu dealership?

 

ya he said dealership above..yikes..your ring/pinion is gonna be toasted

 

The tranny and TC do not take the same type of fluid. Using one in the other will cause damage. The tranny fluid is less "slippery" than the TC fluid, it helps the syncronizers match speeds quicker, if the wrong fluid is in there, it will be hard to shift gears because the syncros will need more time to match shaft speeds. It will also cause other problems with bearings, etc.

However, an improperly adjusted clutch will also make it hard to shift. Even though the pedal travel is disengaging the clutch enough to put the car into gear at low speeds, it may not necessarily mean the clutch is 100% disengaged. There still may be some "drag". Similar to when you spin your wheel off the ground and you hear the brake pads drag on the rotor. It's not enough to stop the car by any means, but there is still resistance. This resistance wants to keep the input shaft at the Engine RPM instead of letting it slow down to match the correct gearspeed of the next gearset. This will result in difficult engagement and rapid syncro wear. Make sure your clutch grabs at the half way point of the pedal stroke and not any closer to the floor than that.

If the mechanic put tranny oil into the TC you will have a problem with Ring and Pinion wear... which shows signs similar to what you are describing. A worn R&P set will start growling more and more as the teeth tear each other apart. And don't worry, if the mechanic failed to put oil in the TC your car wouldn't have made is 10 miles before the TC grenaded itself. However, if he did use the wrong fluid and the noise you're describing is R&P failure, you still have an expensive repair bill on your hands.

Hope all this helps, might be a lot to digest at once.

EDIT: Basically what I'm saying is I think you have a combination of two problems... incorrectly adjusted clutch and wrong fluid in TC causing R&P failure.

Of course, this is an armchair diagnosis, hard to tell without seeing the car.

 

well, i spoke to the service manager at mitsu this morning. he said to bring it in, and he'll fix whatever it is under warranty.

The reason i chose this particular dealership is because they will do warranty work if you are modded. He said to bring it in and leave it with him a couple days(of course, this means weeks) and he'll fix whatever it is. He said both the T-case and tranny were common problems on the EVO(dir), so, we'll see what happens.

BTW, my clutch doesn't engage right off the floor, but ill adjust it a little further up to see if it helps!

Thanks Steve

btw, what oil goes in the T-case? so i know what to put in once i pick it up from the dealership with my new transfercase....since they obviously can't do it.

 

I think its the throw out bearing. Since you sad it only makes the noise when the clutch is not engaged. Mine makes it to its no problem.

 

it does make it when the clutch is not engaged....i checked this morning with my cutout closed. Makes a howling sound no matter what, that gets pretty freakin loud.
