Converter / Transmission Question
Ok im gonna ask and see if anyone has had this happen to them or knows whats wrong before i drop the tranny and have it rebuilt. My car is doing weird stuff. when its in drive it will sit there for a few seconds to a minute and then go into gear if you set there for a few it will disengauge like its in neutral if you reve it up to about 1800 it starts to pull a little then it catches and seems to be fine until you set then its like it went back into neutral. You can see the rpms change when its in gear and the tranny engauges and disengauges. The fluid lever is fine and the fluid is new. It also does the same in reverse. So is my torque converter or transmission bad. Its a turbo 400 with a b&m 2200 stall. Any help is appriciated thanks in advance

I just checked its a b&m 2000 stall 2000 is the flash speed i bought it new from summit when i bought my year one creat motor. Motor specs out at 425hp/438 ft lbs it has a 218/228 @.050 and .520 lift roller cam in it. I am thinking i might have blown out the converter maybe i need a 2400 any help is appriciated. I did notice the fluid was aerated and was light in color with bubbles im in the process of changing it to see if that helps.

Ok this is gonna sound dumb but how much fluid should be in the converter its a b&m tork master 2000 stall. It has a 10.75 bolt pattern i do not know the the size of it i would guess its an 11 inch. does fluid transfer into the converter from the transmission the reason i ask is i remeber that my buddy only put in a half a quart in the converter before it was installed. So is that right or wrong. Sorry for all the dumb questons and post but I know nothing about transmssions.

You said the fluid is new, did you change the filter also. If you did, did you get the o-ring on the pick up tube right? It can be cut or slipped over the retainer lip. Did you put in a shift kit, make sure all the valve body bolts are still tight. And the front pump is what pumps the fluid into your converter fills it and makes it work. The fluid you put in your converter is like prefilling you oil filter, it prevents damage from dry startup. Last check sure your shift cable is adjusted properly and the detents line up. Ron B.

Shift cable is correct. Filter is install correct for my B&M deep alumium pan, Fluid leve is checked and correct every thing is like it should be. I just finished changing the fluid due to what looked like air bubbles and now it does not even move so im thinking the transmission has bit the dust. I did not install a shift kit. My buddy's uncle has a b&m street/strip tansmission thats a turbo 400 im thinking about buyin if my tranny is bad. Does anyone know if there will be an problems installing that tranny. here is a link to it. http://www.bmracing.com/index.php?id...bcat=16&pid=31

If the oil level is correct and there are bubbles in the fluid and it is pinkish instead of red, I think you have a suction leak in the charging pump. What that means is that your oil pump in the tranny is sucking air....and it won't build pressure like it should. It could be due to a bad seal on the oil inlet or it could be as simple as a leak in the pickup tube/screen in the sump. I would check the latter item before doing any tranny dropping. Drain the oil and remove the pan. Take the filter housing down and see if the seal that the filter tube goes in could be leaking air into the system. If so, change it and cross your fingers. Oh, look the filter system and tubing over really good for any breaks or pin holes..the leak could be there too. If that doesn't fix it, it is tranny repair time, me thinks... Good luck.

1 quart fill to avoid dry start. The pump will take over on start up

RONG, I put in 'dry converters all the time, fill with 2.5 gallons of fluid,and fire it up....then check/fill as necessary.....the pump keeps the converter filled, FIRST.....

Ok back again with some more dumb questions. Well i added 3 more quarts and know the car is moving again. My question is if the filter is not installed correctly in the 2 quart extra pan that my b&m is will the fluid not transfer. I forgot to put in the filter extender and i think this may be my problem. Does the pump pull fluid through the filter into the filter. Thanks in advance.

The pump does pull fluid thru the filter, and then discharges it into the valve body and convertor. If it's low, it can suck air and cause the symptoms described. A really high mileage trans will do the exact same thing, the internal seals wear out and don't seal anymore, leaking fluid around the pistons instead of making them apply.
