I know my TOB is bad because I can hear it knocking at idle and when I press the clutch in it stops. Another thing it does is at first it only did it in reverse. I would notice lots of noise/vibration from shifter first then when slipping the clutch to get moving there is this very un-settling whirling/grinding (idk) its weird. It used to do it once a week or so and now its daily in 1st, 2nd, and reverse. I've also been grinding a lot of gears lately too. I even go as far as taking a second or 2 between shifts and making absolutley sure the clutch is fully pressed in; 3rd and 5th are the worst. If I put 3rd to 5th at like 3500-4k it grinds every time. Is the tranny trash or what? Thanks in advance

i had a similar post like this, but mines is a whining sound. from what people told me is that if the TOB was bad then it would do it all the time, and get worse when you push in the clutch. i think thats what they said. possibly input shaft bearing?

Trannys are something that I've never messed with. I need someone who knows ka trannys well to drive it.

Sooo...What could be happening here?

Try changing your tranny fluid this weekend and see if your still having a problem! Or your synchros might be going bad

I was thinking that. I might just try to find another tranny. I mean it has served me well. It got beat on daily for the past year with all of its glorious 260k. I might pay to have that done if I think it will help. I heard it was a major pain in the cock hole to do. Would it be worth putting redline in it?

You get can get tranny rebuild kit from autozone with synchros and everything for like 130$ so you don't have to spent like 300$ on another tranny not knowing if its good or not. You can send the transmission with the kit to a transmission rebuild place and you can get it rebuilt for like 1-200 dollars.

Very true. A lot of my buds have 240's and I might be able to get one for a hundred or so.
