Howdy. I've recently converted a 727 clutchflight to a conventional transmission using a converter. The clutchflight had been sitting for a while but was a new built and unused transmission. Now effectively I've swapped the case and pump but I only have first and reverse. I've checked line pressure and it's virtually non existent. The pump is new and the valve body was a ok when we spilt it to check. Any thoughts?

BK:
Is this going in a FED or Altered? If it is are you sure you want a Torqueflite that close to your feet or legs?

bikeguy307:
What valve body are you using? Is it a full manual? Reverse or standard pattern? Have moved the shifter through all postions while running it on stands? I don't know of any current 727 valvebodies made that require case or pump modifications, but I'm unsure about the valvebodies used in a clutch flight application. Back in the days of the clutch/automatic hy-brid day builders were doing some strange things to make stuff work. I would swap in a known good valvebody and see what you get. With the valvebody controlling the shifting and pressure regulation in a 727 this would be the first step.

Hope this helps, Dan

retroboy:
The answer is obvious if you think about it. The valve body has no provision for oil supply to the converter. Slip a trans go shift kit into a spare valve body and I should be ready to test on Sunday
