Hello guys, i have some bad news..... now that the Chevy is done i did today a testdrive....after a drive of 45 miles it came to a end,damned. Verry strange but possible and more work now.I have a three on the tree,283 motor.The clutch was ok before installing the new motor so i did not change it,today when driving (after a mile or 40)there was a rattling noise when shifting,when i stopt and wanted to drive again the gears where stuck and making a heavy noise.The strange thing is.....when the motor is off i can change the gears,when the motor is on and push the clutch(gearshift) pedal,i can't change or put him in first,second,....heavy ratling noise The pedal is working,the clutch fork is moving when pushing the pedal,everything is well adapted,nothing loose. Is this a clutch problem ? Do i need a new pressure plate and clutch disc ? Or can it be something else ? Also with this tread a photo of my gearbox. Hopefully you will understand what i was writing here.... Johan
Dijoo, Bummer! I'm not the most knowledgable about transmissions but it sounds like something broken in the tranny. I hope I am wrong about that. Try pulling the bottom drain plug and see if anything with metal bits comes out. You can pull the side cover of the tranny and peak in for a look, I think. Re your other reply, I was kind of kidding about Paris. I know they are crazy there, but figured there might be some nice rural cruising in your area though. Hang in there!
You might have broken one of the pieces on the pressure plate. This would cause the shift fork to push the throw out bearing in but not release the clutch. If you dropped a gear in the tranny you would have noticed. I say this because one dropped in my 1949 P/U and the resulting hole in the side of the transmission told me I had a problem. If you start the truck in 1st gear your should be able to shift through all gear by matching the motor speed to the output speed of the drive line. This would tell you if is just your pressure plate that came a part. Make sure no one is in front of you and you can drive it once you start. The piece might be stuck inside creating the noise. Actually looking back at what you wrote, you would have noticed a difference inthe press you had to use when pushing on the clutch, it would be much softer if you broke the pressure plate. If you can shift through the gears I still think it is a pressure plate issue.
This sounds familiar, as respect to the 3 spd on the steering column. I think I remember a truck I had that the shifter was worn to the point that the transmission would get stuck in 2 gears at the same time and make alot of noise and go nowhere. I think it would stick in first and the shifter pin would release letting me then shift into second gear.....thus locking up the trans. Had to get out of truck and open hood and if I remember...........pull up on the shift lever so that it would line up in neutral. Or maybe it was third that it would pop out off and when I would go into first from a stop the truck would not go. Either way.......2 gears at same time.........noise and truck not moving.
Thanks allready for the support ! I just did some testing.... the clutch pedal pressure is normal like before,yesterday there was also no problem with that.The fork moves ok. I remind now that it happend when i came to a stoplight and shifted from third to second,the gearstick was stuck and when i wanted to drive again i could not shift anymore....the ratling noise. Could it be some trouble in the steering wheel collum ? With no motor turning i can shift in all gears but the second gear is not good,it's loose.All the gears have a "click",the second just "hangs" there and go's not so far up as the rear gear. Also it's sometimes stuck and i have to wiggle the gear stick to come loose so i can shift again.That was also like this before the trouble from yesterday.... Or is it meaby the second gear that is broken or is stuck in the gearbox ? Really don't know where to begin,damned
Ah HA!! Read my last reply..........it is most likely just a REALLY worn steering column shifter, sounds like the problem I used to have. Had to shut the engine off, open hood and pull or push on the shift rods to put them back in neutral, and then it would be fine til it did it again. Look at the arms that come out of the side of the steer column (under the hood)and when it is in neutral they should be even with each other and centered in the opening of the column.............
yes i know that trick but now is the problem bigger.... when i push or pull the shiftrods they move and i can set them in neutral but there is no "click" in second gear in the gearbox....the stick falls down on the steering wheel.When the motor is shut off the truck moves free in neutral,when i start the motor and push the gearshift and want to put him in reverse,1,2,3 is does not go,there the ratling noise starts.... meaby the second gear that is broken or is stuck in the gearbox ? I know.....not easy whitout seeing the problems,i just was hoping on some good tips to do first before taking off the gearbox
Start with taking the side cover off where the shift rods go into the case. You should be able to diagnose and see the problem from there. May have a broken shift fork.
Within 2 days i will give more info.When i pull of the steering wheel...is there something special to look after and are there special pieces in there that can be broken ? if yes...where to order ? That would be a problem i think...was just looking around on the www. nothing found....
I should have been more detailed. I meant to pull the side cover off of the transmission, sorry about that. And........if working on the column, the worn parts giving trouble would be down at the bottom, where the rods attach. May be easier to put a floor shifter in........ but it sounds like you do have some internal transmission issues. Drain the oil out before taking cover off.
Hey i'm back. Just a little update.... Tested the gears again,second gear is ok,that was not the problem.With a little forward and backward pushing it slips in. Motor is off : i take all the gears without using the shift pedal,the truck can't move (thats normal) when pushing him forward and this without any ratling sound. When i do thesame but push the shift pedal in,don't loosen him and push the truck forward...there comes the ratling sound ! I drained the oil,took the site plate off,nothing special to see,also nothing strange in the oil. Like crew_cab1978 and 62 short step wrote is this the pressure plate normaly and hopefully.Anything else possible ? Somebody knows the size i need ? In the manual there is the 11 inch for a 283 motor,the classic parts store tells me it's a 12 inch i need,LMC (sorry classic parts)tells me it's the 11 inch....(also for other motors it's not thesame as the manual) I want to order a clutch kit allready before taking off the tranny,i live in Belgium and have to wait 2 to 3 weeks to arive.... Johan
A word of advice. While you have it apart, pull the flywheel off and have it resurfaced by a machine shop. Over the years the flywheel will develop high/low spots and small cracks. Resurfacing the flywheel will assure that the clutch & pressure plate will last a long time in there. If you don't have a machine shop available, then consider a new flywheel. Val
While you are getting the flywheel resurfaced get a new throw-out bearing. If you have another transmission that you are not using take the input shaft out and use this to allign the pressure plate before tightening it down. This will make the installation of the transmission much easier. Also I know that you want to get the parts before you take it apart, but it would really make you mad if they are the wrong size when they arrive. Also you might identify other problems while apart, and have to order additional parts. This would save you an additional 3-4 weeks of down time for additional parts to arrive.
While pondering your rattling noise.....I remembered something that happened in my flatbed truck once. For some odd reason the input shaft would destroy the pilot bushing and would make horrible noise when you would push in the clutch. Bushing would only last 2000 miles. Changed trans, problem gone.
Sounds like you may have 2 problems............worn shifter and something else. Does it make noise only when you are shifting? Noise no matter what gear you are in?
Yes,there is only noise when shifting. When pushing the clutchpedal without shifting there is no noise. I can't get in any gear when the motor is turning. When i put him in gear and than start the motor,he makes a lot of noise and "shocks" forward,no good sound.
You are correct Val,i will shure do that,there is a machine shop not so far away.A parts shop that have the pieces....thats something else Viva USA
You are correct abouth the parts crew_cab1978 ! My friend has a special tool to alling pressure plates. Friday and saterday the work starts with taking out the gearbox...hopefully it works out ok without taking out the motor first This is the kit from Classic Parts,but first i gonna messure it before ordering. Clutch & Pressure Plate Kit - 12" 62-78 Quantity Price: $199.95 Part # : 90-009K Year : 62-78 Ships: Product Description This is a brand new part not rebuilt, and carries no core charges. It includes pressure plate, clutch disc, throw out bearing, pilot bushing, and the alignment tool. Fits 62-68 283-327ci, 72-78 350ci and 69-72 Big Block trucks.
Sounds like pressure plate to me now. My guess is that it will be 11 inch that you take out. Good luck..........
