i have a stock BW t-5 behind a 350 i installed this summer. as far as i know it has never been rebuilt. Lately, when i start it up in the morning and put it in reverse (it warms up for about 10 minutes) it grinds like crazy going into gear. It doesnt do it with any foward gear, and for the most part, the problem goes away after about 25 minutes of driving it. it seems to get worse when i rev the engine with the clutch in, and then try to shift into reverse. the clutch is new if that helps any, and the throw-out bearing chirps like crazy(havent had time to fix it yet). IS there something wrong with the tranny, or should i just ignore it? I've never dealt with trannies before, so if it has to be rebuilt, its gonna have to go to the shop which i cant really afford right now, so, any advice/comments you have will be greatly appreciated....

sounds like the synchronizers or clutch slipping check alingnment.

how would i go about doing that?

Put it in a forward gear right before you try to put it in reverse!!!! That's all you have to do to make it quit.

I've bought trans's from people who didn't do that. You ought to see how much metal it sheds into the fluid from grinding the teeth.

thanks RB8, that seems to be helping out quite a bit. It still does it a little bit, but not as much as going right into reverse..

I can't necessarily explain this technically, but if you let out on the clutchsome while putting pressure toward reverse, it will fall right into gear before the clutch engages.

1st thru 5th gear have synchronizers that line up the gears before you engage them. Reverse does not. If you put the trans in 5th gear first, then shift to reverse, with the clutch in, reverse wont grind. You can shift it to any gear you want first, but 5th is easiest since its right above reverse.

sounds like the clutch isnt disengaging completly and the synchros are masking the problem in forward gears.

ok, so ive tried pretty much everything suggested in the above posts, it still grinds like crazy. So lets say my clutch isnt completely disengaging, what can i do
to go about checking and or fixing that problem?

they all grind going into R. mine did when brand spanking new 1989. The only way for it NOT to grind is to go into 1st first. It becomes a habit after a while

I agree with Larry, I've gotten to where if I get in the car I shift into 1st. anyway, you said your clutch chirps, I think I know what you're talking about if it does it at the very bottom of the pedal travel, right? how do you get rid of it?

Good to see I'm not the only one who rows into 5th then reverse. Makes it much simplier.

I just learned a simple test to see whether or not your clutch is dragging. Let the car idle in neutral with the clutch disengaged. Wait for the car to get a steady idle then push the clutch in for 5 seconds then shift into reverse. If the tranny grinds then your clutch is not disengaging properly and the input shaft is spinning. Do not mistake grinding for normal gear noise. It would be warpage on any of the 3 clutch members, air in the system, carpet under the pedal or to much freeplay. If you are going to check the throwout bearing then it would be simple to sheck the clutch while the tranny is out. I don't know if your clutch is self adjusting or not but try lifting the pedal up as far as it will go. That should adjust the linkage if possible. good luck

the most common cause for the chirp is bad throwout bearing, and you have to replace that. However ive replaced mine three times within the year, and i am just now finding out i have a bent shift fork, so thats got to get fixed too. Im glad to hear this grinding is normal and its not time for me to get a new tranny, that would have sucked...
