4000 rpm's at 60, no 3rd?

Can you manual shift it? Do you know the stall?

Not sure what you mean by manually shifting it? If you mean manually going from 1-2 I can do that. Although it's hard to manually put it into 1 as the linkage needs to be adjusted some.

And I don't know the stall. The engine and torque converter are out of a motor home. I'm not sure what the tranny is out of but I know it's not the motor home tranny because that was swapped out due to the tailshaft.

mine does that when its low on fluid. you are checking fluid in nuetral, warm and running right?

I'm checking it running, warm, and in park. I've always checked my cars that way. I'll check it in neutral and see if it's any different.
