I have a 69 SuperBee with a 440 mildly built with a 727 trans. As soon as I put it into drive , 2nd or low it starts to slide the front tires. I cannot hold the rear tires to keep them from pushing. I have a CR21 stall converter and acording to Torqueflite Patty it should be a 2800 to 3000 stall. I am only at 750 to 800 idle speed and it is pushing. What could the problem be? It has been doing this ever since it was built. Could the Reverse / Low band be to tight?
Thanks

Are the rear brakes working and adjusted right.Are you sure that the tach is correct? You shouldn't have enough rpm to push the fronts at that low an RPM. That is not a trans problem. A stall converter is still engaged as soon as you put the car in gear. The stall rpm is where it's fully applied.

Are you sure that you got the converter in right so that it isn't binding up. When you installed it to the flexplate did you have to pull the converter forward to get it to mate up to the plate or was it snug and binding up to the plate? You should have had to pull the converter forward to mate up to the flex plate.

Stumpy: Yes the rear brakes are working Tested that also.
Mopar:Yes I had to pull the converter up to the flex plate to get it bolted in. I also spun it around before bolting it up just to make sure there was nothing in a bind.

Ordinarily I would say that the problem is in the converter, a failed stator clutch would result in reduced stall speed but this usually kills the motor as soon as it's put in gear.

Sounds like you have two problems, a faulty converter and faulty brakes.

John: That was happening at first and I just brushed it of as a new tight converter. I did loosen some up after a few days but not enough.

hi
cr21 = cast crank hi stall.

low band not applied in drive , so it is not the band .

best guess = bad convertor !

Well I was going to find the problem one way or the other so I droped it into low and hit it WOT. Heard something pop and then had no reverse. Pulled the trans which was a lot of fun with full length headers and opened it up to find a broken low reverse band. I had the converter tested and there was little to no clutch slipage at all. So now I get to rebuild the trans again and get a good converter with a 26-3000 stall. Any recomendations on the converter?
