[DeTomaso] Techno question: ZF pops out of second gear

[Christopher Kimball]

I recently fixed a problem with my '72 which kept popping out of second 
gear--I found the linkage was actually rubbing against the ZF because the 
bracket that holds the shift trunion in the engine bay was flexing.  There 
is a piece of metal on one side of the bracket that is welded to the frame 
to keep the trunion bracket secure, and on mine the weld had broken which 
allowed the trunion to shift from side to side just enough that when I hit 
the gas and/or turned in just the right way, the shift linkage would hit the 
edge of the ZF causing the car to pop out of second gear.  I drilled a hole 
through the piece and the frame and put a large bolt in to hold it in place 
and the problem is fixed.  (Doug Braun helped me locate the problem by 
watching the linkage while I moved the shifter.  He could see and hear the 
rubbing, but it took me crawling under the car to actually find the problem. 
  There's no way the cause could be seem from the top view).

It's a long-shot, but you might check to see if your trunion bracket is 
secure.
