T&T: Borg Warner Transmission

[Jon Ayers]

I have a B-W model 10-14 transmission mounted to a Ford Lehman 135 on a 
Grand Banks 1990 36 operated through Morse Teleflex cabling. Recently the 
transmission got stuck in forward, fortunately not at an inopportune moment. 
I disconnected the Teleflex cable from the transmission, found the lever 
stuck, but it responded to a gentle hammer tap, and would work freely as 
long as the lever wasn't extended to its full throw in forward. There's no 
problem in reverse. I lengthened the Teleflex cable about 1/8" and the 
shifting problem disappeared for about 50 operations, after which it 
re-appeared. If I'm careful about shifting from neutral to forward so that 
the transmission  just engages, all is well.

Question: is this indicative of the need for overhaul? Will I damage the 
transmission if I repeat the cable adjustment problem so that the 
transmission just barely engages? If I understand the B-W owner's manual, 
there's a ball detent that once engaged, fully engages  the transmission in 
each of the three positions.
