Re: Grinding noise in bellhousing ):
So this is the second trans you have had problems with?
Is this a passenger car transmission? What bellhousing are you using? I am asking cuz a truck bellhousing has a larger hole where the bearing retainer fits into than a car bell does. You can bolt a car trans onto a truck bellhousing and not notice it. What happens is the input shaft does not index on the centerline of the crank cuz it only has the four mounting bolts for alignment. This causes wear on the pilot bushing and will destroy the trans input shaft bearing in a short time. It happened to me thats how I know. Measure the hole in the bellhousing and input retainer on transmission. Posted via Mobile Device Posted via Mobile Device Now that I went back and read that your clutch fork is vibrating and bouncing around I would bet money that this is your problem. Truck bellhousing with car transmission.

Re: Grinding noise in bellhousing ):
A Saginaw when beat on will give you issues. No matter what. You can go Muncie but you will pay for it through the nose. You can get a slush box but a 700r4 needs some mods for abuse even behind a stock engine. Transmissions are just one of the things that hurts your wallet no matter what

Re: Grinding noise in bellhousing ):
You do know that a 700R4 is an automatic right? Comparing one to a Saginaw 3 speed is like campairing apples to oranges. While neither of these transmissions are known for strengh or durability, they are not junk and usually don't just break on their own. On the other hand, anything will break if you beat on it hard enough. I am suprised you could even find a Saginaw 3 speed in NC. This is a very popular circle track transmission cuz they are cheap and fairly reliable. Do you know why your last 3 speed failed? Did you check which bellhousing you have?

Re: Grinding noise in bellhousing ):
So you started a thread asking for help with your transmission problem. Now that you have taken it apart and hopefully figured out what was causing it, would it be too much trouble for you to share your findings with the board?
Did you just put an automatic in and call it good? Who knows, maybe someone reading this in the future may learn something from this. Posted via Mobile Device

Re: Grinding noise in bellhousing ):
i thought it looked kind of weird, some of the internals had surface rust on them. the "mechanic" that installed it said it was a "good" transmission

Re: Grinding noise in bellhousing ):
Your probably right, do you think it would be a lot of work to convert it from a manual to a automatic?

Re: Grinding noise in bellhousing ):
Do you still have the original saginaw? If you do, Why not swap the input shaft/bearing (if it's the same model) and get that thing up and running again? Shouldnt be too difficult to do. Clean the "new" housing out, pull the "old" input shaft and bearing and change them out. But one other word. The back end of that input shaft should contain some roller bearings. pack them good with some wheel bearing grease.

Re: Grinding noise in bellhousing ):
One of the gears are damaged because the metal got in them and chipped some of the teeth off

Re: Grinding noise in bellhousing ):
Best bet cregs list or a trans guy. There are specialty junk yards too, like for corvettes and such. Do a Google search for your aria.

Re: Grinding noise in bellhousing ):
So both transmissions failed cuz the oil looked weird and the internals had surface rust? Did you/they put new oil in when they installed it? Just seems odd that weird oil would cause 2 transmissions to fail....
