Trans Stalls Motor

[powerstroke432]

I have a 2001 7.3L f250 with a 4R100 trans and a Banks trans command system. Occassionally in cold weather when it is shifted into reverse it will stall the motor two or three atempts later it will move. It didnt bother me to much but yesterday it did it when put into drive the first time and it hasn't done it since. Has anyone had this problem and could it be the Banks module causing the problem. Thanks

sounds like the converter is on the way out and locking up causing it to pull the engine down and stall it

I thought about that to this truck has the banks trans command and engine brake on it so i believe that the banks system partially controls the converter lock up for the brake. I guess i should un hook it and see if the problem goes away

Or the solenoid that controls the TC lockup has some trash in it and not working properly.

Can it be removed and cleaned or just replace it?

[greasltn]

Sometimes cleaning works, but it doesn't take much to foul the solenoid. You must be very careful to get it spotless.

Now this morning as i left the driveway it acts as though the tc is locking and unlocking rapidly for about a half mile then was ok

If your transmission filter o ring seal on the suction tube has given up it will suck a tiny bit of air and kill your motor.

Add a little bit of tran fluid and see if it gets bedder

One way to check my idear is to park it on a down hill grade (front of truck downward) and see if it will die when going into reverse. If it still dies then you prolly have sumpin else going on.

Worth a check and its ez to do.
